Slash the silence of the great outdoors with amp-packed sound of the Skullcandy LINK Hydration Pack. Get both hydration and audio in this full feature 3-season pack. With its expandable pocket open, you have room for the biggest coats and gear or zip it down and it's a super stable, low-profile, breathable summer system.

The pack is also armed with a battery-powered amplifier that fires sound out of 60mm speakers embedded in the straps. The speakers are weather-impervious, carbon-fibre woven custom jobs designed to be used in rain, snow or shine while the integrated Mobile-Mic buried in the strap allows you to take phone calls completely handsfree.

Also included is the Skullcandy Soft Touch Panel sewn into the mid-strap that will allow you to control power, volume and phone function.
