Rated 5 out of 5 by from Excellent for work out and beyond This shirts are soft and absorbent, excellent for a workout. Because they are nicer than the average gym clothes, I feel comfortable wearing them to a pre-workout lunch.

Rated 5 out of 5 by from Former "other brand" fan For many years I have bought another major brand. I purchased 1 Columbia shirt (because it was on sale). I loved it so much, instead of buying my usual "other brand", I bought 4 more Columbia's. Fitis great, fabric is comfortable and effective for hot environments as well as great colors. Will be buying more.

Rated 5 out of 5 by from Zero Rules Short Sleeve Shirt Great fitting shirt for those hot and humid days and nights. I always wear the same shirt but in long sleeve while kayak fishing during the day but look forward to switching to short sleeve when I come off the water or at night. Great product and very comfortable

Rated 5 out of 5 by from Great shirt with great wicking I wore this during a photo walk in Manhattan and I actually couldn't believe how comfortable it kept me. It was in the mid 90's and the shirt never actually felt wet against my skin even though I was sweating quite a bit. This shirt performed 100% as described.

Rated 5 out of 5 by from Perfect for hking I purchased two of these shirts for long distance hiking where I wanted ultralight shirts that would dry quickly. I'm often not crazy about some high tech synthetic materials feel against bare skin (especially when sweating), but these felt great. Will by more for sure.

Rated 4 out of 5 by from Length This T is so soft and it is perfect for hot or cold weather, looks great, washes easy (cold water & light heat tumble) Only problem is it could use another 4-5 cm in length. If you have any "gut" it may not be for you, I have a a little pounch and love the tee.

Rated 4 out of 5 by from High Tech Tee Shirt Bought to wear underneath PFG shirt. Comfortable and a good fit. So far the only complaint is the tee shirt sleeves are longer than the PFG sleeves

Rated 5 out of 5 by from Outstanding Shirt These shirts are great! I ordered 3 short sleeve and 2 long sleeve. The fit is great and the quality is superb. The Omni-Freeze Zero technology is terrific. It is 85 degrees here today and I am feel cool in my shirt.

Rated 5 out of 5 by from Zero Rules !! anyone still wearing cotton shirts for their outdoor adventures and activities need to reconsider. And give these a try. They are light, comfortable, and Breathable. I hardly know I have them on when I'm fishing, hiking or running. Great Shirts !!
