Currently seeking funding through a Kickstarter campaign, the SOL Water Bag from Tortoise Gear hopes to help adventurers in all facets by providing an easy way to access clean drinking water. Simple in both design and use, all one needs to do is fill the bag with water and leave it in the sun to purify. Thanks to a solar-powered sterilizer, the pack is designed to work in any outdoor scenario, and depending on the rays hitting the bag it can purify water in 3 to 24 hours. The material is BPA-, DHP- and Phthalate-free to persuade the ecologically conscious outdoorsperson, and comes in three sizes suitable for any excursion. But along with acting as an on-the-fly water filter, the bag is designed to also act as a measuring container, and oddly enough makes for a great waterproof bag for ones valuables. The plastic is even touch-screen friendly, so one can use his or her smartphone while keeping it safely dry inside the bag. This adaptable accessory is a must-have for any outdoor enthusiast, and seamlessly combines functionality and practicality into a minimalist package. Pending a successful Kickstarter campaign, which offers a bag for as little as a $3 contribution, this bag could become as ubiquitous as a flashlight or compass in future outdoor adventures.
