The Wasp has been a long time favorite in the UD line of hydration packs, so we did't want to change it too much. We simply updated the materials and spruced up the styling.
The Wasp still has a great fit and rides smooth with access pockets on the front and a secure place for your reservoir in the back.
The seamless back panel eliminates chafing, the soft cool wick material promotes air flow and the Power stretch mesh allows you to cram it full of gear - all so you'll forget you even have a pack on!
