If you've been searching for the perfect base layer for all of your outdoor activities, then your search ends with the Rab Women's Force Tee. The Force works perfectly while layering, thanks to its slim fit and lightweight design, making it a great piece for rapidly changing weather conditions and stop-and-go sports. It also excels as a short-sleeve sun shirt, with built-in UPF protection and a quick-drying, moisture-wicking fabric that keeps you from sweating when you're setting a fast pace on the trail. And since Rab knew that you'd want to wear this layer every day, they threw in an odor-control treatment, meaning no one will know if you wear it for multiple days between trips to the washing machine.
