The AT-15 Backpack from Alpinestars is a technical motorcycle backpack of 15 litres (expandable to 18 litres) that Alpinestars developed for off-road and adventure riders.
The most striking feature? A separate compartment for spare Tech-Air airbag system gas cartridges. Riders using Tech-Air who plan longer off-road trips can replace an empty cartridge en route without interrupting the ride.
The construction is logically focused on durability in rougher conditions. This motorcycle backpack can take a beating. On the wear-prone areas – underside and contact points – Alpinestars uses 900D reinforcements that withstand abrasion, brush and impact. The base material is water-repellent textile. A foldable rain cover comes standard with the backpack for when it really starts to come down.
The ergonomic back panel has a pre-formed curve that matches an active riding position. Inside, a rigid frame ensures shape retention and good weight distribution. The shoulder straps combine multiple foam densities with a breathable mesh outer layer. The detachable belt with quick-release offers extra stability while riding.
The magnetic chest closure snaps shut with one hand. Even with motorcycle gloves on. Compression straps keep the load stable and prevent the contents from shifting on rough terrain. The zips lock automatically and do not open by themselves during riding.
Inside you find a separate compartment for a hydration system (bladder not included) with a pass-through for the drinking tube. M.O.L.L.E. loops on the outside allow attaching extra accessories. Mesh inner pockets provide organisation without extra weight.
The AT-15 Backpack is built for motorcycle riders going off-road who want to keep their Tech-Air system operational en route. The combination of the gas cartridge compartment, reinforced construction and ergonomic fit makes this a specialist choice for serious adventure riders.
