Our take on the LifeStraw Sip with Carry Case

The LifeStraw Sip is a reusable stainless steel filter straw that removes microplastics, bacteria and parasites from drinking water. It uses a high-flow membrane so sipping feels easy rather than labored, and it lasts about 1,000 liters, roughly a year of daily use. At 10 inches and 3 ounces, it slips into a bag and comes with a leak-proof carry case. It suits travelers, campers and anyone wary of tap water abroad; against plastic bottle filters it is slimmer and more durable, though it filters only what you sip through it, not a whole bottle.
