The Sirrus is a great-looking pack with load-carrying comfort that’s hard to beat. The main compartment feels really large for a pack of this size, and is accessed via a long zip that makes it really easy to rummage around inside it. The harness is wonderfully secure, with padded mesh straps that always feel cool and comfortable, and an incredibly soft, padded waistbelt that flexes with your hips as you walk. It has a concave mesh back system that allows for really good airflow without holding the weight too far away from the back, so load-carrying is stable and sweat-free. There are a variety of useful pockets, including two on the waist strap, one on the shoulder strap, and two near the top which are really useful for storing hats, gloves and snacks.
