Race 4 is ergonomically shaped and perfectly balanced to follow your every move without being in the way. The main compartment is placed centered in the back for a comfortable distribution of the weight, while the side pockets are kept relatively small to make way for your moving arms. The belt is made in comfortable and lightweight materials and with the backside covered in a soft and breathable 3D mesh for optimal ventilation. The belt is easy to adjust while moving, even when wearing gloves – just pull the waist straps forward to tighten and just as easily release them for a looser fit.
