This flexible bike backpack can safely handle any Alpine crossing and any difficult uphill and downhill trail. The multi-impact protector from SAS-TEC SCA 500 is integrated into the ergonomic body contact back system and can be easily adjusted to the body size or back length using the hip belt, which is height-adjustable by 6 cm. The light shoulder straps in combination with the breathable, fully enclosing hip belt with side fastener ensure a secure fit in rough terrain. The large, attached front compartment has numerous pockets for organizing tools, spare tubes and pumps. Wallets and keys can be safely stowed in the inner mesh pocket in the upper front compartment. Additional mesh pockets are located on the side and on the right hip wing. A flexible helmet holder, which can also be used to transport full-face helmets, and a removable rain cover are included. Both can be stowed in the bottom compartment. If you are very thirsty, the hydration bladder compartment can hold 2 - 3 l. Other features include: an adjustable chest strap with drinking tube holder, key holder, flashing light holder, glasses holder, side compression straps and reflective elements.
