Great Material!

  • Familiarity: I've used it once or twice and have initial impressions

I really enjoyed the stretch grid material that this shirt is comprised of . It wicks and breathes amazingly well. I was able to use it while coaching this last week of fall baseball, and felt that it stretched really well while performing faster paced athletic movements like swinging or bending for a ground ball. I think this is due to the stretchier side panels and panels around the shoulders and neck that aid in the shirt's ability to conform to your body while moving. Might be my new favorite T.

Nice Shirt

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Large

Shirt is very light weight- great for these hot summer days.

Wicks moisture and dries pretty quickly.

Durability is a concern as the material catches very easily to any type of protrusion. For example, I can feel my calluses "catching," on the shirt if I run my palm up and down on the face of the fabric.

It's also pilled and "fuzzed up," a bit on the front of the shirt after a single wash.

New favotie running shirt

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XL

This shirt is my new favorite to exercise in. It's very lightweight and comfortable. I'm a size 35 chest so am in between a large and extra large. The large would have been way too tight. The extra large fits great in the shoulders, chest, and torso. It's slightly longer than I like in overall length and sleeve length, but that's due to an average height guy needing to wear an extra large. The material is very thin and lightweight. It would probably snag and run easily, but unless you snag it on a branch or something, it will be fine. Will purchase another when one of my other exercise shirts are worn out.
