What Our Gearhead(R) Experts Are Saying:"I've taken this pack on quick-hit ridge missions, and the waterproof body is a huge relief when weather shifts. The AEROFIT carry system hugs close without feeling restrictive, and the roll-top closure makes it easy to adapt the volume during big days out."Long days in mixed mountain conditions demand a pack that stays light, protects our essentials, and carries comfortably when the pace never really lets up. The Syclon XP 30 answers that need with a waterproof main compartment, taped for dependable storm protection, and a roll-top design that gives us room to adjust as layers get added or shed. Its body-hugging AEROFIT(TM) carry system allows air to move between our back and the pack, keeping things cool during sustained climbs and warm approaches. Quick-access storage sits exactly where we need it: a front stash pocket for gloves or a wind shell, dedicated side pockets sized for 1L bottles, and hipbelt pockets for snacks or small essentials. When the trail steepens, the walking-pole attachments and side compression straps stabilize the load, while the rear bladder compartment keeps hydration accessible without digging into the main compartment. Built for efficient movement and steady protection in unpredictable terrain, it's the pack we trust on hut-to-hut routes and lightweight thru-hikes.
