Absolutely perfect. Athletic fit and superior quality material

Man… so close to perfect

I was excited to finally buy these, as I had come across them a while back. And it was time to get some new shirts. While the shirt itself is fantastic, the neck opening is WAY to small for my liking (I don’t like things taught around my neck), and I don’t have a large neck by any means. Anyway… I returned the shirts. If I the tight neck opening doesn’t bug ya, I’d recommend the shirt 100%.

The best shirt I’ve ever bought

This base shirt is the most comfortable shirt I’ve ever worn, let alone the best base layer for your uniform. The fabric is high quality and wicks sweet so nicely! Living in Texas, this shirt is perfect for the hot and humid climate and keeps my skin from feeling wet or sticky. I love this shirt and use it for everything. It’s thin enough to wear underneath and also looks great to wear around. Ive been waiting for a brand with the style and mission of Terra Arma which caters to people that get after it and gives back to our heroes! I havent been this excited about quality clothing. If you are in the military, a public servant, or anyone wanting durable lightweight clothing, you will love this shirt.

Tier 1 comfort

I’ve been in the Army 11 year. The Catalyst Luxe is the most comfortable light weight Tee on the market today! Breathable, Dries fast, and no chaffing. 10 out of 10 recommended!


Catalyst Luxe is a fantastic product that I bought on a whim at the PX. Best unintentional purchase I’ve ever made at the PX. The shirt is worth the investment and came in handy during my recent trip to Hawaii. The high quality material kept me comfortable and moving the entire time, allowing me to roll through several engagements without having to stop for a uniform change despite sweating buckets in the humid tropical environment. Already recommended the Catalyst Luxe to a few friends.
