BUILT FOR PRACTICE, GAME AND SCHOOL: A spacious main compartment fits training apparel, a change of clothes, a 15-inch laptop, books and the rest of your gear — for sport practice, school days, daily commutes, weekend training and athletic team travel. Sized for athletes, students, commuters and active adults. AIRS OUT WET CLEATS AND GEAR: A dedicated zippered shoe compartment with ventilation keeps cleats, sneakers and sweaty post-workout footwear separated from clean clothes and tech, airing out odor on the ride home. Built for daily sport rotation, weekend tournaments, baseball and softball practice, soccer practice and after-school practice rotations. STAYS DRY ON WET FLOORS AND FIELDS: A water-resistant base helps keep contents dry on wet locker room floors, rainy parking lots and damp practice fields. Multiple webbing clip points let you attach keys, a 32 oz water bottle or a carabiner light for fast access between practices and travel — organized carry for the daily school + sport rotation. ORGANIZED ACROSS 3 COMPARTMENTS: 6 zippered pockets distributed across 3 compartments keep training and school essentials sorted — protein shakers, lifting straps, a phone, a wallet and game-day tape live separate from your laptop and books. Plenty of room for team branding too, with the Defender 5 family also offering Small (45L), Medium (59L) and Large (100L) duffel formats for athletes who need more haul space. This product is not intended for children 12 years and under.
