Worth every penny!

I bought this shirt on a whim and was so pleased with the product that I bought a second one! It's breathable and as comfortable as cotton. I love it!

My favorite technical t-shirt

I've worn my Delta Cool T on long hikes and long runs in hot and humid conditions and I love it! It wicks away moisture really well and is also super comfortable to wear on the long hauls.

Comfortable and Cool

Unfortunately my hiking plans to test this shirt were derailed by weather so I decided to put it to the test on one of the most humid days of the summer in Rhode Island while doing yard work and mowing my lawn. After 3 hours outside, I’m happy to report it performs as advertised! With a dew point in the 70s and sun beating down on me, I felt as though the porous material kept the air moving through the shirt while wicking the sweat away and keeping me relatively cool despite the oppressive conditions. Highly recommend!

Perfect Outdoor T

I've put roughly 100 Miles in this shirt so far and have really enjoyed adding it to my collection. One of the neat things about this piece is you almost hardly notice it's there on long runs/hikes where most other pieces might get heavy/hot with sweat. So far its exceeded my expectations and looking forward to putting more miles in it.

Excellent Summer Hiking Tee

Hiked with this tshirt on a really hot day and was impressed with how light weight and cooling the Delta T is. The material this is made from provides excellent cooling function. The shirt also dries very quickly. The only thing I would suggest is to wear a size up from size you would normally wear. Great new T from Burgeon!
