I bought this for my Dad to replace a Summit jacket he loved but was worn out with holes in the sleeves and ribbing. I originally bought a Large but needed to change it to an XL and customer service did that easily with no issue. The jacket was backordered but after waiting a few months, I was notified it shipped and arrived within the same week. My dad loves it and said it fits perfectly! Now he is ready for winter with a new jacket. Thanks so much!
