Alpha AR Jacket

Arc'teryx equipped the Men's Alpha AR Jacket to cater to climbers and alpinists alike. Its fully taped, 3-layer Gore-Tex Pro shell ensures waterproof protection and breathable performance, yet the jacket itself manages to weigh in under a pound.

Just because the jacket is incredibly lightweight doesn't mean it's devoid of features that will enhance your experience in the harshest of conditions. Underarm vents allow you to take control of your temperature regulation while you're working hard in the mountains, while the helmet-compatible hood keeps you fully covered in case a storm blows in. The large hand pockets are situated high so as to not interfere with your harness or backpack's waistbelt, and the secure internal pocket is perfect for extra snacks or your phone. An athletic fit provides bulk-free comfort, and Arc'teryx's ergonomic patterning means that the jacket moves with you, allowing you to comfortably climb demanding ice pitches and set steep skin tracks.

Alpine Versitility

The Arc'teryx Alpha AR is a alpinists best friend. With Gore Pro membrane, pit zips and helmet compatible hood this jacket is designed with high output pursuits and inclement weather in mind. While the minimalist design and lightweight package ensure it won't weigh you down.

I'm trying to decide between a size M and L for this jacket. I am about 6 ft 3, very lean and athletic build. 38 chest and 34 arms. I'm worried the M won't be long enough in the arms or torso. What would be the best choice?

Hey Iain - Based on your measurements, you would probably be best suited with the Arc'teryx Theta AR Jacket in Medium which is the longest in the AR line-up. I am 6'1" with a 39 inch chest and wear most regular and athletic Arc'teryx shells in Medium.
