Super soft

Super soft, cute, comfortable, and love that it has thumb holes. I wish it came in a size xs though

Absolutely love this performawool top!

Absolutely love this performawool top, cozy zero never lets me down!

The material is a soft to the skin feel, lightweight yet enough substance to keep me warm in these cooler fall and winter temperatures.

I love the thumb holes too!

Fit is more true to size than some of the other styles, I ordered a medium and I definitely could have gone with a small for a more true fit but the medium means if I wanted I can put a tank under or just have a slightly more relaxed look (for reference I am 5’7” and 125lbs )

This is a great transition piece. One that you don’t want to take off!

Exactly what I wanted for shoulder season

I’m 5'7", 130 lbs and ordered a Small. The fit is just right—not skin-tight like a base layer, but still looks streamlined enough for running. I wore it on a chilly morning trail run and didn't feel overheated once the sun came out. The merino feels so soft against my skin. I honestly didn't expect wool to feel this smooth, with none of that usual itchiness. Even after the run, it didn't have that usual sweaty smell. This has quickly become my favorite for those in-between weather days.

My new favorite workout tank

I love this tank! The orange tie-dye is so cute, and it’s lightweight and breathable enough for workouts without feeling clingy. Super comfortable, flattering, and definitely one I’ll be reaching for all the time.

As soon as I saw this tank I knew I needed it and I am not disappointed one little bit!

The material is so soft and lightweight, it has enough stretch to be comfortable to move with you either for running, lifting weights or just on a daily basis.

Washes like a dream, hang to dry.
