User Review: Arc'teryx Men's Beta SL Jacket
Fabric: 340NR GORE-TEX® Paclite® 2L
This is my first Arc'teryx product. This is a simple, lightweight, no non-sense rain jacket. Don't expect any excess zippers, flaps or insulation with this jacket. Top quality construction on this one. It has an athletic fit but has enough room underneath for proper layering (which you will need as the jacket seems to provide no inherent warmth). It packs down small too so it won't take up much room in your pack. I believe this jacket and a pair of Alpha SL pants will suit me well for those Colorado afternoon showers.
I would recommend this item, but try to get it on sale. As with all Arc'teryx product, pricey but well worth it!
As far as sizing goes, I am 6'3" 195 lbs and I found that an XL fit me in length perfectly (L was a bit to short in the way of sleeve and torso length).
