The Elite Tri Box Triathlon backpack is designed to fully cover the needs of the advanced athlete since it offers four modalities for its use and when you want to store it, you will also have the advantage that it is foldable and easily compressible. This Elite box allows you to carry it in STANDARD MODE, the most common for low activity athletes in competition because it gives an opening in the top cover where you will find a wide and divided compartment for the cycling bag and race bag. Extend it to have everything at hand. In the PRO MODE of this backpack for professional athletes, you can place the shoes on the bike and leave the racing shoes in front of the box. The LITE MODE gives you a quick transition in small spaces as you can remove the top cover and place it below with which you save volume in the area. Finally, the PRO-LITE MODE is perfect for advanced athletes with very little space where you can only unfold one of the shoe bags and remove half of the bag to place it below, which greatly reduces the volume. This triathlon backpack includes a towel for a comfortable transition and an interior bag to separate wet clothing of the dry clothing.
