I’m 5’4 and 140 lbs, pear-shaped, so I bought size L, especially after seeing another review from someone of the same size. I want to love these Icebreaker tights, and I do like them a lot, but I’m surprised at how loose the waistband is. It’s not integrated elastic but a band sewn in, and it doesn’t feel high quality. I feel like they’re almost falling down, and believe me, this is almost never a problem for me (hips!). Also if I slim down at all (which is part of the goal, hence the investment in snazzy running tights), they’re going to fall right off.
The fabric is also a bit thinner than I expected, which is great on one hand (I don’t want to run in thick wool most of the year) but I almost wonder if it’s a bit revealing.
I do love that they don’t smell after a few runs (without washing in between). I bought them mostly because I travel a lot and can’t carry multiple pairs of running tights or wash things every day, and it seems like they’re good for that purpose.
