Osprey Siskin 12 Mountain Bike Backpack - Ultimate Red

The Osprey Siskin 12 is designed for day-long mountain bike rides. Neither too small nor too bulky, it offers 12 liters of well-optimized space to carry all your essentials: inner tube, tools, pump, spare clothes, and hydration system. With its Ultimate Red color and compact silhouette, it combines style and practicality.

An ultra-comfortable mountain bike bag

The Siskin's priority? To offer you maximum comfort, even on technical descents. It features AirScape™ suspension: a ribbed foam back panel and a central ventilation channel ensure excellent ventilation while keeping the load close to the body.

Add to that breathable BioStretch shoulder straps and a wraparound Airmesh waistbelt with zippered pockets, and you have a pack that stays stable, even on rough singletrack.
