Catalyst Tee

  General Information:  - Proprietary Terran fabric is soft, stretchy, and durable - Antimicrobial so you wont stink - Partially recycled product - Raglan shoulders and flatlock seams for a guaranteed no chafe - Additional "tail" in the rear to stay tucked - Compliant with Army, Air Force, Navy, federal agency, and most first responder agency regulations - Not for use as pants  Explanation The Catalyst Tee is Terra Arma's purpose. We set out with the goal of creating the most comfortable, durable, and functional shirt for military, public servants, and other first responders ever.  While it may look simple, the Catalyst has functional details hidden in it.  The raglan cut shoulders paired with flatlock seams increase strength and relieve chafing while wearing kevlar or a plate carrier.  The neck is dual ribbed Terran which will prevent stretching and the dreaded "bacon neck" you find in other shirts. Finally, the slight tail in the rear will keep your shirt tucked while bending or crouching. You will look forward to wearing your uniform with the Catalyst underneath.

Super comfy and nice athletic fit! Don’t expect extra room or a baggy fit!

Ripley Naylor
Comfy and Nice but hard to wash.

You have to cold wash and hang dry, that’s my only complaint.

Fabulous shirt!

This shirt is incredibly soft & comfortable. The fit is perfect and true to size. Great for an undershirt or working out!

Kathryn Hargrove
So comfortable!

5'4" and 157 lbs and a medium fit me perfectly! The material feels so soft, I look forward to working in these!

Best shirts I’ve owned

I ordered 2 XXL shirts. TRUST the size charts I’m an XL in most sized and the chart said I’m a XXL. It fit perfectly. The quality is incomparable to any shirt I’ve owned. I’m in the Army and will wear them under my ACU blouse. I will wear them just because as well. I hope Terra Arma makes these in other colors. I will order more.
