First off are they loose or compression? From the look of them they look like compression but whats with this picture on their homepage: maybe hes just wearing one thats way to big for him? I have been using under Armour compression shirts and for the most part im happy, but I heard that rupture makes really good rash guards so ill give them a try. If im a L in UA should i get the same size for rupture? Also has anyone tried the 15%off code that they have for signing up for their newsletter? For me its not working. If you have a rash guard you like better than rupture please recommend.
