Our Long Sleeve Tee is designed to be a slightly warmer version of the skin you’re in. Crafted with quality and comfort in mind, the hip-length L/S Tee’s slim fit with a classic crew neckline takes you from a dawn patrol sweat session to a day packed with friends, a meeting with the boss (even if that is a meeting with yourself), big dreams… or wherever your plans might be!

Crafted from super-fine 17.5 micron 100% Merino, our lightweight 180 gsm jersey knit is breathable, funk-free, temperature-regulating, and buttery soft from day one.

Bonus: Our certified mulesing-free Merino is also regenerative and sustainable. (which also means it is free of BPA, PFAs, and toxic forever chemicals).

SWAG 2025: Our capsule collection is a small batch, meaning only a limited number of our Sustainable Wool Athleisure Gear (SWAG) 2025 Long Sleeve Tees are available.

Super cozy staple

This top is very well made, super soft, and I absolutely love the teal color of this year. The thumbholes are soft and comfortable, and the material is worth the price. I got an xs and it fits but is still roomy, even with slightly athletic shoulders and arms - I’m 5’2” 110lbs. Giving 4 stars because I wish it was a mock neck instead of a crew. Crew necks are very easy to find in merino wool, but not universally flattering. If this top was a mock neck I would buy every color and live in them. As is, I love this for a base layer or lounging around. It is also a little long, I’m petite and I practically covers but whole butt lol. Overall very happy with the top, and with all of my branwyn pieces! Just hoping for more variety in the cuts one day :)

Nice Base Layer

I sized up so it wouldn't be tight and love the looser fit. This T will be the perfect base layer for hiking.

I love the SWAG line from Branwyn. The material is weighty, durable, and great quality.

Love it!

Love all the SWAG items! This long sleeve was a staple for me during the colder temps under the SWAG hoodie, and sometimes I even had the SWAG tank under when it was super cold (because I'm always cold). The longsleeve tee helped me to stay warm. I am bummed they aren't making more because I just found them and stocked up but am already sad for when I eventually end up wearing any of the items out I won't be able to replace them :(

Lightweight and gorgeous weave

This long sleeved tee is more like a dressy sweater but it’s lightweight and makes my skin happy. It keeps me warm and cool. I just received it and will assume it washes like my Branwyn underwear which I can’t live without.
