The Nathan Sports VaporCloud 2L Hydration Vest is a race vest of such quality and hydration/energy food capacity that it is capable of providing for men involved in such ultra events as the 103-mile Ultra-Trail du Mont-Blanc (UTMB).

This high-quality vest with its 2-litre bladder and water bottle pocket that can accommodate a 650 Tru-Flex bottle will provide the required hydration needs. And the design even provides insulation for the bladder pocket so that the hydration liquid does not get warmed by transferred body heat.

A wide range of pockets of various designs will give you the capacity to carry energy gels, electrolyte tabs etc as well as a pocket that is smartphone compatible.

You will not want your vest’s contents bouncing up and down or from side to side as you tick off the miles as it will be so uncomfortable and could cause rubbing sores. It is good to know, therefore, that the Nathan Sports VaporCloud Hydration Vest takes steps to avoid such potential discomfort in two ways.

Its dual-stabilisation system compresses the bladder and the rest of the load but also the load-lifter system works to provide further stabilisation by keeping the equipment, hydration, food etc raised and close to the body so it moves as a more homogenous load in closer synchronicity with the torso.
