Amazing feel and stretch!
I wear these everywhere!! On the trail, fishing, backyard, anywhere outdoors. Its got an incredible feel and stretch. Its pretty good at breathing but not elite. However ill take the heat in exchange for the great look, snaps, and collar. I even wear these to work in 100 degree days over the summer. Go get one they look and feel great.

Ran smaller than I had expected. More of a summer dress shirt than a work shirt I intended it for.

New favorite hiking shirt
I wore this shirt hiking in the Utah National Parks this month and it was the absolute best piece of gear to bring. Quick drying, incredibly breathable, and protected me in the 85 degree sun. I wore it most days while wearing a pack and there’s absolutely no pilling on the fabric where the pack made contact

I noticed that this shirt is thin. Backcountry's product description says UPF rating is 50+. Yet, the tag says UPF of 30.

Great Shirt but please answer my question!!!
Great shirts! Could always use more solid colours! But one question to the designers…why the odd choice of slanting the fabric orientation on the left front shoulder/chest? It really keeps the piece as an outdoor garment and limits the wearability in a travel/city situation.

Great lightweight shirt. Work in the private security sector. Have nearly every color of the Astroman line. OR makes some quality products. Been using them since working in SOF.

I put this to the test
Great shirt. I've with our 2. I have a Med and a Large and both fit week (510/180). Can't say enough good about this shirt. Classy, protective, form fitting. I hunt, fish, shoot prs matches, do yard work, and eat dinner out in this thing. I live in AZ and sun protection is a must. Everyone 2-3 of these. I've used them heavily for 3 years and they are just starting to look worn. That's pretty fair, other shirts don't get that far.

Great short
This shirt is super light and comfortable. I wear this when kayaking. Breathes well and protects from the sun. It’s a tad brighter color than anticipated, which is just my personnel preference. But overall a great shirt for outdoor activity then out to eat or drinks.
