Just buy these amazing socks!
I’m with slimmer calves, the S size fits great. Cushion is just enough to protect my feet on rocky terrain without feeling heavy. Highly recommend these amazing socks!!!

A must have thermal kit for winter!
I’m 5’8″ / 130 lb, wearing M. The thermal tee is plush yet not heavy; the underwear layer gives just enough stretch, and the pants keep my legs warm even when the temperature dips. I’ve worn the kit on both chilly morning hikes and gym — it does both equally well.

Lovely thermal kit!
I’m 5’8″ / 150, size L — the All-in Thermal Kit feels thoughtfully proportioned. The long sleeve and bra layer beautifully, with enough merino warmth that I stayed comfortable all day. The leggings conform without squeezing, and the fabric breathes well even in damp conditions.

Functional and stylish
I bought this set because I needed something technical for winter jogging but also casual enough for travel. I’m 5'6″ / 125, ordered S — the proportions are spot on. The seamless design means no irritation, and the Cappuccino looks really nice. It’s rare to find a merino outfit that’s this functional and stylish.

Love this set
I’m 5’7″ / 120 lb, size S — the fit is spot on. The bra gives just enough support, and the leggings have stretch but feel structured. Love this set.
