Carter H. ★★★★★ Oct 22, 2026

I've been wearing these under everything for the past week, and the fabric really does stay odor-free even after a long day at the office. The waistband sits flat under leggings without digging in, which makes everyday comfort easy. Definitely a solid choice for lightweight daily wear.

Nicholas ★★★★★ Oct 21, 2026

I was a bit worried these would ride up, but the merino corespun fabric keeps them perfectly in place all day. They're super breathable and haven't shown any signs of wear after several washes, which is exactly what I needed.

These are the softest underwear I think I've ever owned, the stretchy fabric moves with me all day without ever digging in. Wore them on a hot hike and was genuinely surprised how fresh they still felt at the end.
