I'd say they could be used year round except on the coldest of nights. Having the half-lining up top is nice. I haven't worn them much since they arrived as they are a bear to get on over my potato farmer calves but I'm hoping they stretch out a bit.
Really nice, though.
Edit. They seem a bit coated. Not sure with what but basically I think they will keep out the cold a bit better than the L0s.
