Overview
A 34-liter, two-compartment daypack from JanSport with a padded 15-inch laptop sleeve, front organizer pocket with key clip, and mesh water bottle holder, built for daily school or commute duty in the Cherry Lacquer maroon colorway.
JanSport's reputation for durability shows up in the review pile more than in any single spec sheet line: parents report bags surviving a full year of daily overstuffing, and some say they are on their third generation of family members using the brand. The tradeoff for that 34L volume is bulk, so this suits someone carrying a full course load rather than running a light errand.
- Measures 17 x 13 x 7.5 inches for 2,100 cubic inches of storage
- Weighs about 1 lb 7 oz empty
- Metal pulls and stamped hardware on the zippers
- Dual exterior quick-stash zip pockets
Who it's for
Fits students and commuters who need to carry a laptop plus a full day's books or gear in one bag, including families who have used JanSport packs across multiple kids. Less suited to anyone wanting a slim, minimal daypack.
Pros and cons
- Two large main compartments plus a front organizer with key clip
- Padded 15-inch laptop sleeve zips apart from the main bag
- Mesh water bottle holder and top carry handle
- S-curve straps and padded back panel spread the load
- 34L build is bulkier than a minimalist daypack needs to be
- Recycled polyester resists wear but is not stated waterproof
Performance notes
The separate 15-inch laptop sleeve keeps electronics away from books and bottles riding in the two main compartments.
