You must take into account the 3 different types of garments: regular fit, perfect fit - the garment is adjusted - and ultra fit - the garment is very tight. Depending on your tastes, you can choose one or the other. In the case of choosing an ultra-fit jersey, we recommend that you wear one size more than usual in jerseys. In case of regular fit, it is possible that a size less than usual is perfect for you. In case of doubt it is advisable to always choose the immediately superior size.
