TOUGH MUDDER, 4-20-2012
Reviewer: BBM - BOOM BANG MUDD
The HAMMER was awesome. I wore it in the Michigan/Ohio Tough Mudder last Saturday, April 14...and it served the purpose. I was stoked at the durability and flexibility of the product. It fits true to size, so if you are an athletic fit or muscular build...consider a size up. I ordered a 2XL and it worked great. order yours today and get MUDDIN.
Great fit, 1-28-2012
Reviewer: Charles Holm
These fit me great. Just remember these are made for athletic builds. With 7.5 to 8 inch smaller waist than chest. If you are getting a gut or have a small chest, keep this in mind and you will have no trouble sizing. Other brands fit big guts much better.

Reviewer: Stacey G
Have not had a chance to try this out in the open water yet, but it fit perfectly based on the size chart. I am 5'10" and weigh 145 lbs, and the size small was a perfect fit. Nice roomy arm holes. I purchased this to give me an extra layer of warmth under my full wetsuit for those really really cold swims. I think it's going to work out perfectly.

Reviewer: Mork from Ork
If in doubt go up a size - glad i did! By the sizing chart I was either large or XL. If you are a little more muscular then go up in size.

I swim warm water tri's and it's perfect for large upper bodies that need flexability. Sizing chart right on.
Good quality but sizing chart is wrong, 4-16-2009
Reviewer:
It's a good quality vest, but I followed the sizing chart and couldn't even get the mid section to stretch enough to get down past my shoulders, so I decided to just stick with Surf T's and just gave the vest to a friend.
