The LifeStraw Sip is a reusable filter straw you drink through directly, no batteries or pumping. Its hollow-fiber membrane removes bacteria, parasites and microplastics, and the filter is rated for up to 1,000 liters, roughly a year of daily use. At under 3 ounces with a carry case, it is one of the lightest ways to treat water on the go. Against pump filters and gravity systems it trades speed and capacity for weight and simplicity; against basic squeeze filters it adds microplastic removal. Owners rate it highly for travel, hiking and emergency kits.
