Whether you're solo bikepacking, setting up a family basecamp, or heading out on a weekend backpacking trip, one thing never changes: you need safe water. That's exactly why we built the LifeStraw Peak Series 3-in-1 Water Filtration Kit, a modular filtration system that adapts to how your adventure unfolds.
Three Ways to Filter in One Kit
The Peak Series 3-in-1 Kit is built around a simple idea: no two adventures are the same, so your water filter shouldn't be one-size-fits-all. This kit gives you the flexibility to filter water three different ways — as a straw, a squeeze bottle, or a gravity system — all from a single compact kit.
As a straw, dip directly into a lake, river, or stream and drink on the go. Perfect for a quick refill on the trail.
As a squeeze bottle, fill the included 650mL Squeeze Bag from a lake, river or waterfall, attach the Peak Series Solo Water Filter, and squeeze safe water directly into your mouth or another container. Great for on-the-move hydration when you need convenience.
As a gravity system, hang the 3L Gravity Bag, attach the filter and hose, and let gravity do the work. Set it up at camp, walk away, and come back to filtered water ready to drink, cook with, or share with the whole crew.
Everything You Need, Nothing You Don't
The kit includes the ultralight Peak Series Solo Water Filter, the 650mL Squeeze Bag, and the 3L Gravity Bag with hose, plus a cap and backwash syringe to keep your filter flowing at peak performance. The entire system is built to be lightweight and packable, so it won't weigh you down whether you're counting every ounce on a thru-hike or loading up the family car for a camping weekend.
The Solo filter screws onto 28mm thread water bottles too, so it plays well with gear you already own.
Water You Can Trust
Whatever mode you're using, the filtration performance stays the same. The Peak Series Solo Water Filter removes 99.999999% of bacteria (including E. coli and Salmonella), 99.999% of parasites (including Giardia and Cryptosporidium), and 99.999% of microplastics, along with silt, sand, and cloudiness.
With a flow rate of 3L/minute, you can fill a 1L bottle in just 20 seconds. And with a membrane microfilter rated to last up to 2,000 liters, this kit is built to go the distance with you across many seasons and many miles.
Adventure More. Worry Less.
From the first sip at a backcountry creek to the last cup of camp coffee, the Peak Series 3-in-1 Kit is ready. Its re-engineered filter reduces clogging from sand and silt, so you get a consistently strong flow rate over the long haul. The premium materials are durable enough to handle rugged conditions without worrying about rips or punctures.
