Amelia ★★★★★

The warmth-to-weight ratio on these is almost absurd. They pack down to nothing in my backpack, but my legs stayed toasty on a freezing morning hike without feeling bulky under my pants. Honestly, these might be the smartest ounces I carry now.

Leo V. ★★★★★

Wore these under my hiking pants on a freezing morning and forgot I had them on until I took a break. The warmth-to-weight ratio is ridiculous—they feel like nothing in the pack but keep your legs toasty.

Avery R. ★★★★★

Slipped these on under shorts for a chilly morning hike and couldn’t believe how warm my legs stayed without any bulk. They pack down so small in my bag that I forget they’re even there until the temperature drops.
