The main difference between TRAIL PRO + and the TRAIL PRO model is a fifth pocket with a YKK zipper for important things. The hip belt- is suitable for many types of outdoor activities: running, cycling, trail, etc. The capacity of the TRAIL PRO+ is the same as the TRAIL model, maximum of three liters. In terms of functionality, it is less than ULTRA, but more than TRAIL. The main purpose of the TRAIL PRO+ model is long runs and dynamic trail races, where it is important to firmly capture a small amount of heavy equipment (half-liter water bottle, etc.). Also it`s great for regular daily running. The main difference from other models is the material of large pockets, Cordura-stretch. Strong, but at the same time elastic, it fixes heavy objects better. You can put only your phone and keys in it, as well as putting everything you need for a run or a long trail race. Large pockets hold soft bottles of 0.5 liters. Made of soft elastic fabric, which makes the hip belt light, comfortable and at the same time very capacious. Four pockets: two large on the front and two smaller on the sides. Pockets have quick access on the go. The fifth pocket has a YKK zipper. It is one-piece and put on over the legs. Made in Ukraine.
