Just as a reminder to those who are responding to justme, that "3-4 season" means different things to different forumites. In this case, he apparently lives in Wyoming, where the season called "summer" includes snow, hail, and frigid lashing winds on any day of the year.

I don't think a hammock could under any stretch be used in a Wyoming winter. You'd need a "5-season" hammock for that!
