Can anyone comment on what the waistline/rise is like on these things? And is the full-length a heavier warmer fabric than the 3/4 length?
Rise is at "natural waist", not low-rise. The full-length is the Insulator (warmer) fabric. The 3/4 is the regular (lighter) weight. In the spring, I think we'll have the tight in the lighter weight as well, but went with the insulator weight for the winter.
