Not sure what has taken so long, we have had sneakers that had an air bladder, why not backpack until now. Topeak has bridged that gap.
A revolutionary cycling specific backpack which uses pressurized air to fine-tune personal comfort and fit. Multi-channel air chambers located in the hip belt and back contact area inflate with an integrated micro pump and release valve providing infinite adjustability.
Constructed from lightweight and durable 210 denier nylon, the form fitting and aerodynamic Air BackPack features multiple storage compartments including: full length center zipper providing main access; separate top loading Hydra Core compartment; zip side panel; side water bottle pocket; built-in, fold-out helmet holder and hidden pull-out rain cover. A clip-in Gear Core keeps gear like mini pumps, tools, tubes and more in separate pockets and can be removed when more storage is needed
