Modeled after a surf-style fitting rash guard, the Immersion Research Thick Skin is made with 200 weight, 4-way stretch polyester fleece (9% polyester/7% spandex) that is low bulk, dries quickly, and as a result has an excellent warmth to weight ration. The tight fit allows the shirt to absorb less water, and it doesn’t sag when damp.
