Flume 1/4 Zip Baselayer

Very soft, well constructed and warm. Nice fit that is not overly tight

New version/fabric is even better

I have the original version and the new one. Both great but I like to new fabric even better.

Great Baselayer

Breaths super well, and I like the slightly loose fit. Also resists smell well. The tall size worked great for me in Large Tall for a 6'6" 240lb guy with a longer torso and arms than legs.

Amazing Base Layer

Best Baselayer I ever bought. I tried it on a few winter hikes in the past weeks and it is both warm, and breathes really well which allows for comfort in a wide range cold and less cold temperatures.

I need more

I am ashamed to admit that I love this shirt so much that I wear it entirely too many times in between washing. Embarrassing I know, but it feels so good and helps regulate my body temp so well I can wear it layered for days in a row.
