Norrona /29 Tech Tee
Here's what other sites are saying:
Wear the Norr''na /29 Tech Short-Sleeve T-Shirt under your softshell jacket when it's a bit chilly in the morning. Besides wicking moisture to keep you dry and comfortable, this action-ready shirt uses Polygiene tech to inhibit the growth of stinky micro-organisms so your climbing partners don't have to smell your stank when you're stuck on a ledge switching out the lead.
