...if you have a sensitivity/allergy to silver, I do not recommend it. Don't get me wrong, this is a great base layer. Fits like glove and will protect you from the elements without adding bulk. No bunching, riding up anywhere. But, I'm allergic to silver, and it didn't really occur to me that the reason my torso was breaking out in an itchy rash wasn't the detergent I was using. The reaction also didn't start well after a year I purchased the garment, so that's why I didn't put 2 and 2 together.If you need a great base layer and tolerate silver, this garment is for you.
