Excellent Arm Warmer
March 28, 2013

These are a huge upgrade from the previous Smartwool Arm Warmers I have. First, the silicone logog on the inside and outside of the top cuff keeps the arm warmer in place and prevents any slipping which is perfect for someone w/ long skinny arms like myself. Second, with the HyFi material anything you need to put on for extra warmth slips on easily and will resist future "pilling." Finally, you can never go wrong w/ the benefits of wool. I highly recommend and won't go anywhere without these in my pack.

Pros: Great design, Build quality, Performance, Ease of use, Great value
