Product Reviews

Rated 4 out of 5 by from Usually I am a 5 Stars Reviewer, but this fell a l The fabric of the shirt is really good. I only did not give this 5 stars for 2 reasons... it seems like the cut is a little roomy for an undershirt, which I think has more to do with Voler than Hammer. Second, the bright red Hammer logo on the chest is well-placed for seeing it with an unzipped jersey, but the red is so dark that it shows through a few of my white jerseys and makes is a little harder to see the logo on the chest. All in all- these are minor issues, but I always try to leave honest reviews for others considering the products!

Rated 5 out of 5 by from Great material I love the material, but these shirts run large, not small. The arms are extra long so I turn them back about an inch & a half. The tail is also a bit long. I like it to stay tucked in my shorts but not pull when I lean forward. I use this for sun protection with a SS jersey and the neck opening is too large exposing my upper chest if I unzip my jersey. But, this issues will not stop from me ordering more.

Rated 5 out of 5 by from Aero sleeveless shirt I received this shirt just before a trail run at Brown County state park. It was very hot and humid. This aero shirt is great at keeping you cool and dry. I had no problems with sun burning through the shirt like other thin shirts I've worn. I'm ordering a few more for mult-day races.

Rated 5 out of 5 by from I know you classify it as an "Undershirt" Here IN HOT FLA its a great workout shirt all by itself. Just worn it on a 52 mile paddle over the holiday weekend and it worked great!
