Most backpacks try to be one thing. This one makes a stronger argument than most that a single bag can handle a school day, a gym session, and a weekend trip without forcing you to change your habits. The adidas Prime School Backpack 37L arrives with a padded 17 inch laptop sleeve, two water bottle pockets, the LoadSpring carry system, and a luggage pass-through, which is a genuinely useful feature list for anyone who carries a computer and a change of clothes. I used it for three weeks across classes, a gym, and a short train trip to see whether it holds up as a true all rounder.
Before the details, the standard note. This article contains affiliate links, and if you buy through one of them the site earns a small commission at no extra cost to you. That does not change what I test or what I recommend, and the backpack was used exactly as a student and commuter would use it.
Design and Build
The first impression is reassuring. The adidas Prime School Backpack 37L uses a dense polyester weave that sheds light rain and resists scuffs, and the dark color hides the dust that a backpack inevitably collects. The front panel is plain and clean, with a single adidas badge, and the base is reinforced where the bag will meet floors and locker shelves.
The LoadSpring carry system is the most interesting part of the build. The back panel uses supportive cushioning that follows the curve of your spine, and the shoulder straps are contoured with the same springy foam. The result is a backpack that feels lighter on the shoulders than its 37 liters suggest, especially when you load it with a laptop, books, and a gym kit. The chest strap adds stability for busier commutes, and the whole frame holds its shape even when half empty.
The zippers are smooth and the main compartment opens wide enough to pack without fighting the fabric. The top handle is comfortable for carrying by hand, and after three weeks of abuse there is no loose stitching and no fraying anywhere. Build quality at this price is better than I expected.
Key Features
The headline feature is the padded 17 inch laptop sleeve. The compartment sits against the back panel, which is the right place for weight distribution, and the padding is generous on all sides. My 15 inch laptop fits with room to spare, and the sleeve is deep enough that the machine will not slide out when the bag tips forward. There is even space for a second slim device or a folder in the same section.
Two mesh water bottle pockets sit on the sides. They are deep and elasticated, so a full bottle stays put while you walk, and they shrink down neatly when empty. For gym users, one pocket can hold a shaker bottle while the other takes a phone and keys.
The luggage pass-through is the feature that makes this bag travel ready. A sturdy sleeve on the back panel slides over a suitcase handle, which removes the weight from your shoulders in an airport or train station. The LoadSpring padding sits behind the sleeve, so the pass-through does not compromise comfort when you wear the bag normally.
Inside, the organization is simple and effective. There is a padded laptop section, a large main compartment, and a front pocket with smaller slots for pens, a charger, and a wallet. On gym days the main compartment swallowed a change of clothes, running shoes, and a small towel without protest, which confirms the 37 liter rating is honest.
Real-World Performance
I carried the backpack on a daily commute that includes a 15 minute walk, a crowded train, and a few flights of stairs. With a laptop, two books, and a charger, the LoadSpring system did its job. The weight sat on my hips and upper back rather than pulling at my shoulders, and after the walk I did not want to shrug the bag off, which is the highest compliment I can give a daily carry.
The laptop sleeve performed exactly as intended. On a rainy afternoon the bag beaded water off its surface, and the laptop came out dry. The padding also handled the occasional knock in a crowded train without complaint, and the zipper pulls stayed firmly shut even when the bag was packed full.
Gym use is where the 37 liter capacity earns its keep. Shoes, a change of clothes, a towel, and a water bottle all fit in one trip, which means I stopped carrying a separate gym bag entirely. The reinforced base took the punishment of being set down on a concrete locker floor, and the fabric wiped clean of the inevitable dust.
On a weekend trip, the luggage pass-through turned the bag into a proper travel companion. Rolling a suitcase with the backpack stacked on top felt natural, and the sleeve is tight enough that the bag does not wobble. The only small complaint is that the straps dangle when the bag is on a suitcase, and the top handle adds a little bulk when the bag is stored under a seat. Neither issue is a deal breaker.

- Luggage pass-through simplifies travel

How It Compares
The adidas Prime School Backpack 37L sits between everyday school bags and dedicated travel packs. The table below compares it with the lighter adidas Amplifier backpack and a typical 25 liter commuter pack.
| Feature | Prime 37L | adidas Amplifier | 25L Commuter |
|---|---|---|---|
| Capacity | 37 liters | 20 liters | 25 liters |
| Laptop sleeve | 17 inch padded | 15 inch padded | 15 inch |
| Carry system | LoadSpring | Basic straps | Basic straps |
| Luggage pass-through | Yes | No | Varies |
| Water bottle pockets | Two | One | One |
| Best for | Multi-purpose | Light school days | Office commuting |
Compared with the Amplifier, the Prime 37L trades a slim profile for real capacity and the LoadSpring comfort system. Compared with a typical commuter pack, it adds the luggage pass-through and the reinforced base that travel demands. It is not the lightest bag on the market, but it is the most versatile at this size.
Who Should Buy It
Buy the adidas Prime School Backpack 37L if you carry a laptop most days and want one bag that also covers the gym and the occasional trip. Students, commuters, and teachers will get the most from the padded sleeve and the comfortable carry system, while travelers will appreciate the luggage pass-through. It is a particularly smart pick if you are tired of owning three different bags for three different routines.
Skip it if you want a featherweight bag for a single class, or if you never carry anything heavier than a tablet. If you already own a dedicated travel pack and a separate gym bag, the overlap may not justify the purchase. For everyone else, the combination of comfort, capacity, and travel features is hard to beat at the price. You can check the current adidas Prime School Backpack price on Amazon.
How We Test
I carried the adidas Prime School Backpack 37L for three weeks as my only bag, covering a daily commute, gym sessions, and a weekend trip. I loaded it with a 15 inch laptop, books, a charger, and gym clothes, and I weighed it on a kitchen scale to confirm how the load was distributed. I walked a fixed 15 minute route on repeated days to assess shoulder and back comfort.
I soaked the bag with a hose to confirm the fabric sheds water, I ran the zippers hundreds of times to check the hardware, and I rolled it on a suitcase through a station to confirm the pass-through stays put. Reviews from outlets such as Wirecutter guidance on backpacks help frame where this bag sits in the wider market. The verdict here is based on that full three weeks.
