Warm and comfortable
I'm very happy with the 360 Visibility Zip Top! This is my third Sporthill winter top and I practically live in them in the winter. It is perfect for cross-country skiing, just the right amount of warmth, and nice to hang out in it in the cabin. I'm not crazy about the silver zipper, but it doesn't bother me too much.
Do I dare admit I live in my 360 vis tops?
I purchased one in the Fall and just bought another one. The Swiftdry Swiftpro fabric is one of my favorite materials for outdoor pursuit clothing. It is warm but not too warm and very soft to the touch inside. I use this as my base layer for winter hiking and cross country skiing, and will carry it for summer hikes as a coverup. M is a good size for me--average size 10 in tops generally. Good one!
