Cons Expensive, not the most durable, heavy when wetSuper expensive, extremely poor durabilityExpensive, lack of durability, heavy when wetIneffective odor control, warm-weather focusedNot a warm layer by itself, loose-fitting cuffs can get caught up when layering
Bottom Line A staff favorite, this top is the gold standard for staying warm, dry, and comfy on all your ventures and outdoor shenanigansImplementing new and innovative technology, Patagonia brings us a seamless base layer that feels unbelievableThis doesn’t stand out among the crowd, but silently gets the work done without a need for recognitionLightweight, versatile, and affordable, this 3-season powerhouse is ready for warmer-weather adventuresReady for all-day activity, but be prepared with a well-layered system if you're taking this out in the cold
