A four-stage filtration straw to keep on the trail as a backup. It filters the water as you sip, so you can carry less weight on a long hike. We don't have the maker's lab test results to share, so boil or treat water too whenever you can.

It's small and light, and it tucks into a side pocket or a glovebox until you want it.

Pairs well with the Desert Shemagh Scarf for hot days out, or the Trail Starter Kit for the rest of the basics.

Shipping and returns: Free US shipping on orders of $35 or more ($4.95 under $35). Our suppliers pack and ship most orders from their own warehouses, many of them overseas, so orders leave within 1-3 business days and most arrive 8-17 business days after that (about 2 to 4 weeks door to door). You get a tracking number by email. Unused items in their original packaging can be returned within 15 days of delivery (you cover the return shipping). Damaged, missing or wrong items are replaced or refunded at no cost to you. Opened sterile first-aid supplies can't be returned unless they arrived damaged. Shipping policy · Refund policy
