Is this the most perfect tee Smartwool has ever made? Theyll let you decide. Organically grown cotton stays next to skin while the benefits of Merino wool work to manage stink, sweat, and body temperature. Plus, slits at the side seams give this tee a go-with-the-flow feel so you have enough room to move and breathe without unnecessary bulk. For all-day comfort, the Smartwool Womens Perfect Crew Short Sleeve Tee has got it.
