Tips

For best results, wash inside out with like colors and avoid fabric softeners, which can coat Merino fibers and reduce their natural performance. Air drying extends the life of the fabric and maintains the fit. Pair with other Smartwool base layers for a complete moisture-wicking system in cold or warm conditions.
