The LifeStraw Universal Adapter is the next logical step for the water filtration company. Instead of needing to buy one of their bottles, you can now just buy a filter that fits on most any bottle. Nalgene, Camelbak, Hydroflask... you name it.

The kit includes two different size caps that meet most sizes of water bottles on the market, and the filters remove virtually all bacteria and parasites, as well as chlorine and other chemicals. The carbon filters will last up to 25 gallons, and the mouthpeices are made with food-grade silicone.

We've featured other Lifestraw products previously, like the LifeStraw Go as well as the original LifeStraw. It's a great brand with a great set of products for people who enjoy the great outdoors.
