Great for year round use

I've had the Delta Cool T since August give or take. I wore it for 7 years days deep in the North Maine Woods in early September where temps would range from 25 in the morning to 60's & 70's during the day. We were bushwhacking through the woods taking looking to get photos & videos of wildlife. We encountered heavy rains for the first three days. The Delta Cool kept me warm when I needed it and cool when the sun came out. It dried quickly and didn't smell that bad after 18 hour days of heavy use.

I then took it as my main base layer for a back packing trip in the Bigelows. Temps were between low 20's and high 30's. Once again it performed great. It was comfortable and kept me dry and warm. Cant ask for much more.

Since then I use it as my base every time I go skiing. I 100% plan on buying another 2-3 so I got spares.

Love.. Love.. Love..

I absolutely love this T-shirt. It's my go to for when I go hiking/jogging. It's light, comfortable, and it wicks sweat. And even though its as light as terrycloth it's surprisingly durable. I love it so much I went back and bought a second one.

Got the job done on a humid day up Cannon Mountain!

My new favorite hiking shirt! During a very humid trip up Kinsman Ridge Trail to the summit of Cannon, it kept me cooler and much dryer than other shirts I have used in similar conditions.

Best tech T-shirt

I’ve got synthetic and wool t-shirts, all have positives and negative’s. So far the Delta shirt is a big winner. Been on a few hikes and bike rides, dry quickly, wicks great, and the best part is the feel of the material. Like wearing a cotton shirt vs the plastic feel of most synthetics. Will have to wait to see if it develops a funk, but so far its a big winner, wish there were a couple of color choices, really like the green, just would like my second shirt to be a different color
