Sherpa Adventure Gear created the Chonzum Long-Sleeve Women's Shirt out of a high-tech fabric that uses an exothermic reaction to warm up when it's wet, which makes it a great layering piece for cold-weather activities. Other highly useful features of the fabric include water repellency, moisture-wicking capability, and stain resistance. Thumbholes in the cuffs help layers slide over the Chronzum with ease, while a distinctive stitching detail adds a dash of flair to this versatile midweight top.Price: $29.99 (58% Off!)Regularly: $72.95
