Purchased this as an impulse buy since I didn't have any work out tops with a 'turtle neck'. Used it in the gym on leg day and liked it. Would probably be better under a vest when you run outside. Performed well in the gym though! Im extremely pear shaped and the fit was flattering on me. It's identical to the 'Hyba Solid UV Muscle' long sleeve but with a turtle neck. Well definitely very similar.
