When every piece in your layering system has a hood, things can get uncomfortable quickly. That's why Rab made the Women's Force LS Tee — a long-sleeve sun shirt without a hood. UPF-protective fabrics keep you covered from the sun's harmful rays when worn as a standalone baselayer. When it gets cold enough that you need to throw a fleece on, the Force's slim fit is perfect as a baselayer, while the hidden thumb loops prevent your sleeves from bunching up underneath. Odor-control treatment makes this shirt ideal for multi-day treks of backpacking trips and the breathable design helps you stay well-ventilated when you're working hard.
