Who would've thought that a Web site adorned with skulls and handguns would market earth-friendly products? That's right. Link Hydro Pack is a creature of Skullcandy and is here to give you one more reason to leave the car in the garage.

In addition to hauling stuff and letting cyclists hydrate without stopping or taking their hands off the steering bar, the hydro pack comes with Skullcandy's patent audio LINK technology. LINK to bikes is sort of what Sync is to new Ford models. It allows users to listen to MP3 music and experience hands-free calling through the headphones or speakers located on the straps, without ever touching either device. The 3-season pack offers a sturdy H2O extension and pockets wired for a mobile phone and any portable MP3 player.

Link Hydro Pack comes in orange and silver and will run you $150.
