Short answer: the BAGSMART Blast Pro 38L is a good fit if you want an expandable carry-on-style backpack with a few purpose-built organizers, but “a lot of pockets” is not a claim the published specifications can prove. BAGSMART identifies an adjustable divider, ventilated shoe compartment, quick-access lockable laptop sleeve and RFID pocket, yet does not publish a total pocket count. That makes the bag more suitable for travelers who organize around larger zones than for people who want a separate pocket for every small item.
The decision is therefore less about counting compartments and more about whether its 28-liter-to-38-liter expansion, laptop access and shoe storage match your packing routine. The specifications below come from BAGSMART; no independent durability, water-resistance or pocket-count test was found for this exact Pro model.

What is the BAGSMART Blast Pro 38L?
The Blast Pro 38L is an expandable travel backpack designed to move between a smaller everyday configuration and a larger travel load. BAGSMART describes it as carry-on ready and underseat approved, with a main compartment that expands from 28 liters to 38 liters. Those labels describe the manufacturer’s intended use, not a guarantee that the packed bag will comply with every airline’s size or weight rules.
Its layout emphasizes a few dedicated functions: separating clothing, isolating shoes, protecting a laptop, and shielding RFID-enabled cards. That is a different design philosophy from a backpack built around dozens of tiny organizer pockets. If you prefer packing cubes and open compartments, the Blast Pro’s approach may feel practical; if you want a dedicated slot for every cable, passport, pen and charger, the published feature list does not establish that level of subdivision.

What are the Blast Pro 38L’s dimensions, capacity and materials?
The following are BAGSMART’s stated specifications. They are manufacturer figures rather than independent measurements, so allow for normal production tolerances and measure the packed bag when an airline’s limit matters.
| Specification | BAGSMART’s listed detail |
|---|---|
| Standard dimensions | 31 × 20.5 × 42 cm |
| Expanded dimensions | 31 × 25 × 42 cm |
| Capacity | 28 L, expandable to 38 L |
| Weight | 1.2 kg |
| Laptop sleeve | Quick-access, lockable sleeve for devices up to 15.6 inches |
| Exterior fabric | Diamond ripstop nylon with a PFAS-free water-repellent finish |
| Lining | 240T pongee |
| Exterior zippers | YKK |
The 5-centimeter increase in listed depth is the physical change created by expansion. That extra space is useful for a return journey, a jacket or bulkier shoes, but it can also push the bag beyond a carrier’s personal-item or under-seat envelope. Treat the expanded setting as a capacity option, not as permission to ignore the airline’s maximum packed dimensions.
Does the Blast Pro 38L have a lot of pockets?
It has several named organizing areas, but BAGSMART does not publish a total pocket count for the Blast Pro 38L. You should buy it for the specific compartments listed below, not on the assumption that it has the six pockets attributed to a different BAGSMART model.
Adjustable dual-level interior divider
The divider gives the main compartment two height positions, allowing you to separate one layer of clothing or gear from another. It is most useful when you want a structured split between clean clothing and equipment, or when you want to compress a smaller load without leaving the entire interior as one open cavity. The listing does not describe the divider as a collection of small accessory pockets.
Ventilated, stowable shoe compartment
A dedicated shoe area keeps footwear away from clothes and can be stowed when you need the space for another item. Ventilation is helpful for containing odor and residual moisture after normal use, but it should not be treated as a waterproof wet bag. Place damp shoes in a separate bag before closing the compartment.

Quick-access, lockable laptop sleeve
The sleeve is designed to let you reach a computer without opening the entire main compartment, and BAGSMART lists support for laptops up to 15.6 inches. “Up to” is a compatibility claim, not a promise that every 15.6-inch chassis will fit: thick gaming laptops, ruggedized models and devices with oversized bezels can require more clearance than the screen diagonal suggests. Check your computer’s complete dimensions against the sleeve before relying on it for a trip.
RFID pocket
The RFID pocket is intended for cards or travel documents that use radio-frequency identification. RFID shielding can reduce some forms of unauthorized scanning, but it does not replace ordinary precautions such as keeping your bag closed and monitoring it in crowded places.
What the listing does not establish
There is no manufacturer total for interior and exterior pockets, no diagram that counts every sleeve, and no independent teardown or review that supplies one for this exact Pro version. A related TPU version is advertised with six independent pockets and a 180-degree laptop compartment, but those specifications belong to that separate product and should not be transferred to the Blast Pro.
How does the expansion change the way you pack?
Use the standard setting when you need a slimmer profile, then open the expansion when you genuinely need the additional depth. A sensible sequence is:
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Start with the bag unexpanded. Put dense items low and close to your back, and keep the laptop in its dedicated sleeve rather than in the clothing cavity.
- Set the divider to the level that matches your load. Use the higher separation for two distinct layers; use the lower position when one larger compartment is more useful.
- Place footwear in the ventilated compartment. Bag shoes individually so dirt does not migrate into the lining, and leave room for the compartment to close without compressing the rest of the pack.
- Pack flexible clothing before hard accessories. Soft items can fill irregular spaces; chargers and toiletries are easier to find when grouped in a small pouch.
- Expand only after the main compartment is organized. The additional depth is most valuable for a return trip or bulky layers. Expansion also increases the packed footprint, so measure the finished bag if you are flying.
- Close and test every zipper before leaving. Walk with the bag fully loaded, check that the laptop sleeve still closes without pressure, and confirm that the expanded depth does not interfere with your intended storage location.
The design rewards zone-based packing. Packing cubes are optional accessories, not stated inclusions, and the manufacturer does not claim that any particular cube set is supplied or guaranteed to fit.
Will a 15.6-inch laptop fit, and is the sleeve secure enough?
BAGSMART specifies a quick-access, lockable sleeve for laptops up to 15.6 inches. That makes the bag appealing to travelers who alternate between work and leisure loads, because the computer can be reached without unpacking clothing. The listing does not provide the sleeve’s internal measurements, padding thickness or impact-test results.

Before buying, compare the laptop’s full width, depth and thickness—not just its screen size—with the compartment dimensions supplied by the seller. A 15.6-inch ultrabook may fit where a thicker 15.6-inch gaming system does not. The lockable feature can deter casual access, but it is not a substitute for keeping the backpack within sight in transit.
Is the shoe compartment genuinely useful?
Yes, if you regularly carry a second pair and want footwear isolated from clothing. The compartment is ventilated and stowable, so it can serve as a dedicated shoe zone on one trip and give space back to the main compartment on another.
Its limits are equally important: ventilation does not equal drying performance, and the listing does not claim a waterproof membrane or leakproof seams. Clean and dry shoes before packing, use a washable shoe bag for muddy soles, and keep wet swimwear or toiletries in a sealed pouch.
Can you use it as a carry-on or under-seat bag?
BAGSMART labels the Blast Pro 38L as carry-on ready and underseat approved, but airlines set their own maximum dimensions, weight limits and enforcement practices. A bag that fits one carrier’s cabin policy can be too deep for another carrier’s personal-item sizer, especially when expanded.
Check the airline’s current baggage page for the exact route and fare, then compare those limits with both listed configurations. Measure the bag after packing, including bulging pockets and compression caused by the laptop, shoes and expansion zip. If the carrier permits only a personal item, plan to fly in the standard configuration and keep the profile flexible enough to slide into the measuring frame.
Are the materials durable and weather resistant?
The listed construction is diamond ripstop nylon with a PFAS-free water-repellent finish, a 240T pongee lining and YKK exterior zippers. Those choices suggest an emphasis on abrasion resistance, a treated outer surface and familiar zipper hardware, but the specifications do not provide a denier rating, seam-taping details, load-cycle results or laboratory abrasion data.

Water-repellent fabric can shed light rain for a time; it is not the same as a waterproof dry bag. Protect electronics and documents in internal pouches during sustained rain, and do not submerge the backpack. Because no independent weather or durability test for the Pro model was identified, treat long-term performance as unverified rather than guaranteed.
What independent evidence exists for this exact model?
There is no independent published statistic establishing the Blast Pro 38L’s total pocket count, packed weight, airline fit or long-term durability. A Travel + Leisure search-result excerpt describes a reviewer using a 13-inch MacBook Pro in the padded laptop compartment of the related BAGSMART Blast 38L, not the Blast Pro 38L. That experience cannot verify the Pro’s fit or construction.
Likewise, the separate Blast 38L TPU listing mentions six independent pockets and a 180-degree laptop compartment. Those details are for the TPU product, so using them to advertise a pocket count for the Pro would be misleading.
How much does it cost, and what should you verify before ordering?
An official U.S. BAGSMART result displayed $89.99 in one listing snapshot and $80.99 in a variant snapshot. Those are volatile displayed prices, not a dependable current price, and the supplied page text contains inconsistent warranty and return statements. Check the live product page, the selected color or variant, shipping destination and the current written return and warranty terms before paying.

The backpack makes the most sense for travelers who want one expandable bag with a laptop zone, shoe isolation and a divider rather than a pocket-heavy office organizer. Use this decision checklist:
Best Value
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.
- Powerful Pass-Through Charging: Supports up to 85W pass-through charging so you can power up your laptop while you use the hub. Note: Pass-through charging requires a charger (not included). Note: To achieve full power for iPad, we recommend using a 45W wall charger.
- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
- Choose it if you value a 28-liter everyday profile that can become a larger travel load, need a dedicated laptop entry point, and regularly carry shoes.
- Choose it if you are comfortable organizing small accessories inside pouches or packing cubes instead of relying on many built-in mini pockets.
- Be cautious if you need a guaranteed personal-item fit across multiple airlines, because the expanded depth may exceed a carrier’s limit.
- Be cautious if you require independently verified waterproofing, impact protection or a published pocket count; those data are not supplied for this model.
- Look elsewhere if your laptop is larger or thicker than the sleeve’s stated 15.6-inch class and you cannot confirm the internal dimensions before purchase.
What are the main strengths and limitations?
| Strength | Why it matters |
|---|---|
| Expandable capacity | The main compartment can move between the listed 28 L and 38 L configurations. |
| Purpose-built organization | A divider, shoe compartment, laptop sleeve and RFID pocket cover common travel tasks. |
| Laptop access | The sleeve is described as quick-access and lockable, reducing the need to open the main compartment. |
| Specified materials | Ripstop nylon, a PFAS-free water-repellent finish, pongee lining and YKK exterior zippers are identified by the manufacturer. |
| Limitation | Practical consequence |
|---|---|
| No published total pocket count | You cannot verify that it meets a “pocket for everything” packing style from the listing alone. |
| Airline fit is not universal | Carry-on and underseat labels still require a check against the specific carrier and route. |
| No independent performance testing identified | Durability, rain protection, padding and long-term zipper performance remain unverified. |
| Variant-dependent pricing and policy wording | Confirm the live price, shipping, return window and warranty for your location before ordering. |
Is the BAGSMART Blast Pro 38L worth it for someone who needs many pockets?
It is worth considering when “many pockets” really means a few well-chosen zones: shoes separated from clothes, a laptop kept accessible, an adjustable split in the main compartment and a place for RFID-sensitive items. It is not a proven choice for shoppers who require a specific high pocket count, because BAGSMART does not publish one for this model.
The strongest case is flexible travel capacity in a 1.2-kilogram package with a work-friendly laptop entry point. The weakest case is a trip where airline sizing, verified weather protection or detailed small-item organization is non-negotiable. Buy only after matching your laptop dimensions and packed measurements to the airline and confirming the current commercial terms.
How should you compare it with other travel backpacks?
Use the same checklist for any alternative rather than comparing marketing labels alone:
- Capacity and expansion: record both the normal and expanded volumes, and ask whether the expansion changes the bag’s airline category.
- Packed dimensions: compare the actual loaded shape with the carrier’s current sizer, not just the manufacturer’s unfilled measurements.
- Weight: include the empty-bag weight when estimating how much of an airline’s allowance remains for clothing and equipment.
- Laptop access and fit: check internal dimensions, opening direction, closure security and padding claims.
- Compartment layout: count only the organizers the manufacturer explicitly identifies, and distinguish a large divider from multiple small pockets.
- Materials and testing: separate fabric descriptions from independently measured abrasion, rain or load performance.
- After-sales terms: verify price, shipping, returns and warranty for your country and the exact variant.
Frequently Asked Questions
Will a 16-inch laptop fit in the Blast Pro 38L?
BAGSMART only specifies laptops up to 15.6 inches, so a 16-inch computer is not an established fit. Measure the device’s full height, width and thickness and compare them with the sleeve’s internal dimensions before ordering.
Is the water-repellent finish enough for heavy rain?
No performance rating or waterproof test is published for this model. Treat the finish as light-rain protection and use separate waterproof protection for electronics during prolonged downpours.
Are packing cubes or a shoe bag included?
The listed package features do not state that packing cubes, shoe bags or other accessories are included. Plan to supply your own organizers if you need extra separation.
Can the bag’s weight trigger an airline fee even when its dimensions fit?
Yes. Airlines can apply separate cabin-weight limits, and those rules vary by carrier, fare and route. Weigh the fully packed backpack at home rather than relying only on its empty-bag specification.
