Grayl Ultralight Water Purifer

The light-weight (10.9 oz.) Grayl Ultralight Purifier is composed of an external 10-inch plastic canister and a tightly fitting plastic insert with snap on filter at the bottom of the insert. To operate, you fill the cannister with stream water and push the insert down into the cannister. The pushing action drives 16 ounces of water through the filter into the insert where it can be consumed or saved with a screw-on top for later. In used condition. Small signs of wear. Please refer to pictures for more detailed information. I am happy to answer questions and post more photos. I am open to reasonable offers and bundles. I have more activewear/outdoor gear in my closet.
