Measure around the chest while wearing the clothing you expect to use with the vest. The Adventure Vest is available in five overlapping sizes. Ultimate Direction specifies slightly different pack capacity and weight according to size.

The wraparound construction distributes the vest around the torso, while repositionable sternum straps and adjustable side compression allow the fit and load stability to be refined.

If you are deciding how much carrying capacity you need, see our Running Backpacks, Race Vests & Hydration Packs Guide. Capacity should be considered alongside mandatory kit, aid-point spacing, weather, pace, access to crew and your preferred carrying strategy, rather than race distance alone.
