This is a great base layer. The thumb holes are good for keeping snow out and your hands warm. The waist zipper would probably be better if it zipped totally off but its functional as is. The hood would definitely be nice if it was removable also. I am 6'4'' about 225 and the xxl is too big in the waist and a little long. For temps up to 30 degrees this is great, any hotter and its too much.
