Quick Verdict: The Blast 38L is a 2.2 lb expandable carry-on backpack (28L to 38L) with a 17.3″ laptop sleeve, dedicated shoe pocket, and a 180° clamshell opening built for airport speed. It’s strong on organization and value, weaker on weatherproofing and long-haul back support versus premium travel packs.

Design, Materials & Build Quality
The Blast 38L uses a tightly woven polyester shell that feels dense in the hand rather than papery. Zipper pulls are rubberized and easy to grab with cold or wet fingers, and the main zippers run smoothly around the full 180° opening without snagging on the fabric edges. The beige colorway shows dust and light stains more readily than the black version, so it’s worth wiping down after tarmac loading or overhead-bin storage near dirty bags.
Strap padding is generous for a bag in this price bracket, and the back panel has enough structure to keep the pack from sagging when it’s half-empty on the return leg of a trip. Hardware feels closer to mid-tier travel brands than to budget backpacks — the buckles clip in with a solid click and the compression straps hold their tension after repeated cinching.
Organization Layout
The standout design choice is the separate shoe compartment, which keeps dirty soles away from clothing without needing a dry bag. The laptop sleeve sits in its own padded pocket near the back panel, letting it lay flat during airport security screening without unpacking the rest of the bag.
Core Performance & Field Testing
Packed to the 38L expanded capacity, the bag holds roughly 4-5 days of clothing, a packing cube set, toiletries, and a laptop without needing to sit on it to close the zippers. Compressed back to 28L, it slims down enough to pass most airline sizers comfortably, though travelers flying budget European or Southeast Asian carriers with stricter dimension limits should double check the compressed size against that specific carrier’s box before flying.
On rainy test days, the fabric resisted light drizzle for 10-15 minutes before moisture started to wick through the seams — fine for a dash from taxi to terminal, not something to rely on in sustained downpours since BAGSMART does not list a formal waterproof rating on this model.
Stability & Handling
Loaded to 38L, the pack sits upright on its own without tipping, useful in security lines or crowded gate areas. The top grab handle is reinforced and doesn’t stretch under a fully packed load, which matters when lifting it into an overhead bin repeatedly during a multi-city trip.
Sizing, Fit & Transport Compliance
At 2.2 lbs empty, the Blast 38L is lighter than most hardshell carry-ons and many soft-sided competitors in this segment, leaving more of your airline weight allowance for actual gear. The expansion zipper is the deciding factor for sizer compliance — keep it zipped down for strict international carriers and only expand it for domestic flights or checked-bag situations. This flexibility is the main selling point over fixed-volume competitors that force you to choose one size permanently.
Long-Term Durability & Wear Impressions
After repeated loading cycles, the compression straps and main zipper pulls show the expected light wear but no failure points. The bottom panel, which takes the brunt of floor contact in airports and hostels, holds its shape well, though the beige fabric picks up visible scuff marks faster than darker colorways. Stitching around the shoe pocket and laptop sleeve remains tight with no fraying after extended use.

Comparison: Blast 38L vs. Two Prominent Competitors
Blast 38L vs. Nomatic Travel Bag 40L
Nomatic’s bag uses more premium ballistic-style fabric and a more structured frame, but it costs significantly more and weighs more too. The Blast 38L undercuts it on price and weight while sacrificing some of that structural rigidity and the more refined hardware finish Nomatic is known for.
Blast 38L vs. Osprey Farpoint 40
The Farpoint 40 leans more toward a backpacker’s hiking-style harness with load-lifter straps and a hip belt, better suited to walking longer distances with the pack on. The Blast 38L is built more around airport speed and organization — the shoe pocket and flat-lay laptop access aren’t things the Farpoint offers, but the Farpoint carries heavier loads more comfortably over distance.
Who Should Buy It vs. Who Should Skip It
Buy this if you’re a carry-on-only traveler who wants flexible volume for both short city trips and week-long stays, values fast laptop access at security, and wants a shoe pocket without an extra packing cube. It’s also a solid pick for budget-conscious travelers who don’t want to pay premium prices for expandable packs.
Skip it if you regularly hike with your pack loaded for hours, need certified waterproofing for wet climates, or fly airlines with unusually strict compressed carry-on sizers where even 28L might be tight.

Final Score & Rating
8.1 / 10 — Strong value pick for carry-on-only travelers who want flexible capacity and smart organization, held back slightly by weatherproofing and a beige finish that needs more upkeep than darker colors.
