Essential Piece of Gear
- Gender: Male
- Familiarity: I've put it through the wringer
I wear XL in all my Arc'Teryx gear. I'm 6'1" and about 188 lbs with very broad shoulders, a 45" chest and a 77" wingspan (the equivalent of a 6'4" person of average proportions) and the XL in the Atom LT fits very well. There is a little bit of excess room in the stomach and waist area but in the Large the arms were way too short for me and the shoulders and elbows were too tight. If you are of average build and my height with a normal wingspan (take 1.023 times your height in inches to see what the average is for your height) then a Large will probably work fine.
The fit is not real form fitting for me, but also not too baggy, a nice balance so that I can use the jacket with a thin base layer when running, or during high intensity activities, and also layer under it when temps dip or I'm not going to be as active.
I wear this under an Alpha SL in XL and it is great combo. I also use it as part of my winter system:
1. Base Layer (1 or 2)
2. Atom SL
3. Atom SV
4. Alpha SV
These jackets are in XL and when you put all three on you they fit like a glove.
In this photo it was about 0 degrees with the wind chill and with a full pack and pulling gear in the sled, I was getting too hot with this jacket and had to unzip it to dump heat. I only had a couple light wicking layers on underneath. This jacket simply delivers.
