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.

Perfect for running and everything after

Took this on a warm weekend running and ended up wearing it again the next day because it still smelled completely fine. The Merino-Tencel fabric feels silky rather than woolly, and it stayed light even once I started sweating. I love the racerback shape and how nicely it follows the body without looking overly tight. Definitely coming with me on future trips.

The tank I keep reaching for

I’m 5'7", 126 lbs and bought a Small. It fits close enough to be flattering without feeling tight anywhere. I’ve worn it for runs, strength days, and once for an entire travel day afterward. The fabric is unbelievably smooth and has that cool feeling when it first hits your skin. What really surprised me was how fresh it stayed after sweating. I honestly expected merino to feel warmer, but this feels made for summer.

Loving the fabric of this tank! It’s really soft and comfortable and handles sweat so well. I have the blue and pink tanks and wear them for running and pickleball. The fit is perfect for activity and super flattering. I need to get more colors!
