I got this pull on for my birthday which is in July so I really haven't been able to test it yet but my initial impressions are good. The quality and workmanship seems excellent. I am 6' 160 lbs and I usually wear a medium, I got the paradox in a small however and it fits like a glove with a thin baselayer underneath. The fit is designed to be on the trim side but it does not run small. The chest is a little tight but the fabric has enough stretch to fit comfortably. It is also very light and packs down to about softball size. Looking forward to fall so I can put it to use!
