User Review: Arc'teryx Men's Epsilon AR Jacket

Summary

Excellent, highly breathable mid-layer, or cool weather outer! Very water resistant, very abrasion resistant. Comfortable fit

Men's M fits great, 5'10"/160lbs.

This jacket fits very slim, but a medium is perfect for 5'10"/165lbs. I've worn this on top of an 800 fill down jacket, and it's not too tight! The sleeves may be a little long for some, the additional panel by the wrist sits very naturally. The jacket is pretty simple, one waist bungee, two hand pockets, and a flat pocket at the upper left shoulder.

I've never been caught in a downpour with just this coat, however water beads up quite well, still after 2+ years and multiple washings with no treatment. A big plus is the breathability; using this layer between an eVent shell and a base layer is perfect without bulk. I've had it close to soaked with sweat, and it will dry out quickly. The jacket inner has a soft, waffle design that does a good job getting moisture away from your skin. Worn alone, you'll keep warm well into cool weather, but this all really has to do with how well you put together your layering system. 

One of my favorite attributes is just how tough this coat is. After 2+ years of regular wear and many backpacking trips, no rips or tears to report. I fully expect this jacket to be a major component in my system for years to come.
