SirrusA(R) 26 brings true innovation and quality to the ventilated pack world. Inspired by Osprey’s AntiGravity technology, SirrusA(R) 26 provides a fully adjustable AirSpeed ventilated back system which combines single piece construction of the backpanel and hipbelt with highly breathable suspended mesh.

The classic styling and clean design, alongside an impressively comfortable carry makes the SirrusA(R) 26 a firm favourite for walkers and hikers who are looking for a ventilated daypack with enough capacity for spare clothing, food, water and equipment. The detachable raincover stored in the bottom pocket increases weather resistance and tough nylon fabrics ensure durability. SirrusA(R) 26 features a double-clipped lid opening with draw-cord fastening, a large, easy access pocket in the lid and a vertically zipped expansion pocket on the front which is perfect for securely storing a jacket or spare layer for easy access. SirrusA(R) 26 is the perfect pack for warm days on winding trails. SirrusA(R) 26 is compatible with all HydraulicsA(R) and HydraulicsA(R) LT reservoirs.
