    Great Quality & Looking Good!









    Great material, and fit, with comfy netting. These not only look class but also are so light and make running/working out especially on leg day very enjoyable! Love the two logos of MyP and Under Armour on either leg, along with the zip pocket on the back big enough to put yours key/cards in. Will definitely buy the other colour in the future, would definitely recommend. This Under Armour & Myprotein collaboration is perfect, with the quality of Under Armour and the Myprotein logos and colour scheme, these products are top of the range!

    needs pockets



    The only issue with these shorts is there's no pockets to keep your phone and car keys, I use my phone for music so this is pretty annoying. Apart from that the shorts are great, they are short lengthed they cover roughly a third of my quads but I expected that and the material is nice and light.
