Arcteryx Mens Sigma FL Pants Pilot

Season:Sale

Brand:Arcteryx

Code:20089-PIL-

New in for this season, the Sigma FLs are a beautifully constructed pair of mountain trousers that offer excellent wind and water resistance whilst keeping your comfortable from the car right up to the peak (no matter if you're walking, scrambling or ice climbing your way up) and back down to the pub.

The Sigma FLs have been designed to take a beating - whether it's from rock, harsh weather or ice, these pants will protect you on your whole adventure. They balance weight and durability perfectly by using Hybrid material mapping; this places Wee Burly Durable Weave reinforcements in the seat and the knees (so you won't rip a hole in the trousers if you scuff your knees up a tough scramble) and Fortius 1.5, a lightweight 4-way stretch softshell fabric, in the remaining area for comfort and mobility. This combination of materials also creates a snug but non-restricting, trim fit. The trousers also have a DWR treatment, further aiding to resist rain and snow and protect you for longer.  

The features of these trousers are very cleverly thought out and quite special indeed. The waistbelt is adjustable eliminating the need for an extra belt and is also incredibly smooth and low profile meaning it sits comfortably under a harness or the hipbelt on a backpack. The pockets are very cleverly planned - they are all zippered so you won't lose your phone on a steep climb, and they all sit out of the way of your harness. The two zippered hand pockets sit above the leg loops and the singular thigh pocket on the right-hand side sits just under the leg loop; this means you won't have bits and pieces digging into your legs as you go for the crux move. The lower leg of the trousers are tapered from the knee down to avoid getting snagged on crampons or when you're not wearing crampons, it means you can actually see where you're placing your feet when you're on a climb - simple but smart. And finally, the cuffs at bottom of the trousers are adjustable and have grommets so you can install gaiter cord if you so wish - further sealing out cold updrafts.

All of these clever features and attention to detail come together to give you a very smart pair of trousers that you will fall in love with instantly.
