Evernew water carry - collapsible water bottle made of 3-layer low odor polyethylene (BPA free). Offers a few extra features with no weight gain. A cap keeper and a removable shock cord keeps the bottle rolled up and compact. I can't tell you how many caps I have lost. Screw-cap fits Sawyer water filter perfectly.
