Normally when you think of a hoodie, you think of cold conditions. However, that's not the case with the Under Armour Women's Coolswitch Trail Long Sleeve Hooded Shirt. This innovative hoodie was designed to protect you from the sun and keep you cool during active use in warm weather. UA Coolswitch technology makes the fabric cool your skin temperature by up to five degrees when it comes in contact with sweat, so you actually get cooler as you warm up. Plus, it also protects your skin from harsh UV rays when the sun is high overhead.
