This time of year the days can start out cold and stay cold or warm up for a classic Colorado day. The Arc'teryx Rho LT Zip Neck pullover gives you a solid foundation to layer warm and layer well. Rentex Powerflex material allows for a wide range of movement and has a great warmth-to-weight ratio, so you stay toasty (on those cold days) without added bulk. Subtle features like a laminated chest pocket and no-lift underarm gussets make the Rho LT versatile enough for everything from autumn climbing to mid-winter ski tours. We find this top to be super versatile. Use it as your base layer or wear it as your outside top for "Steamboat formal" occasions. It's all good and you'll find you own several... in lots of different colors.
