I read the reviews, and I agree the band makes the sizing run a little small. However, these are definitely not seamless! There is a very large and uncomfortable seam at the most inconvenient place! It was irritating just to walk around the house--I can't imagine a hiking trip. I just found Backcountry and ordered a lot of gear for an upcoming hiking trip to Zion. (Probably, too much!) :) I love this site! They have great prices and reviews. So, I was a little disappointed with this purchase. I would return them, but I already wore one pair from the 3-pack, so I am stuck with $24 worth of underwear that I will never wear again.
