Why We Like The Argon Long-Sleeve T-Shirt

With AirVent technology, the Argon has superpowered wicking and drying abilities, keeping us cool and relaxed through every lung-burning sprint, every jelly-leg-inducing trek, and every pump-fest climb. No matter our pursuit, we move freely and stay chafe free in the stretchy, flat-seam construction, while the anti-odor treatment staves off the stink.

Amazing base layer

Everyday base layer, doubles as sun shirt in shoulder seasons.

comfortable and durable

I wear this for running and MTB. Nicely fit, a tad heavier than capilene cool. Nice sun protection as well.

Men's Argon L/S Tee

I bought this to try it out as a layer in my outdoor clothing. Ended up buying another because I liked the first one. It is a little thin but helps to keep the weight down.

Perfect for hiking

I am 5'10" 205 lbs with a muscular build and the large fits great. The only thing I would change is making the sleeve cuffs a touch tighter but I like the Argon better than the Echo for hiking since it's a little thicker.

Again, OR Hits The Bullseye

Extremely Comfortable; Great fit. I initially purchased it for hiking but find its becoming an everyday, every activity favorite.

Great shirt from hot sunny weather to cool, wet days

I've enjoyed this shirt as a single layer in hot, sunny weather. I started wearing it with a thought to reducing sun exposure. The airy fit and feel work great for hot, sunny hikes. On cooler days it also works as one of several layers. It's a great all-around shirt.

Great light weight shirt.

An upgrade from the Echo. Great as base layer and sun shirt. Wicks great on runs and hikes. Seams don't rub under packs. Will buy more .

Time to buy more

All around great shirt. It has the perfect fit for an athletic tapper and moves where you want to. The sleeves are the perfect length and don't get in the way. I have no complaints!

Love the Argon material and fit!

Size medium fits perfect with nice sleeve length for me, 6'0" 180lb athletic build. I like the fit, it's not boxy and baggy. The Argon is a bit warmer than the Echo so it's perfect for chilly mornings in the spring and fall in Colorado. It's comfy so I find myself also wearing around the house when I need a long sleeve!
