Review: MSR Thru-Link

Instead of stopping to filter water, stay on the go with the MSR Thru-Link Inline Water Filter. Taking up minimal space in your pack, it’s compatible with any hydration reservoir, so just fill your bladder in the creek and let the Thru-Link filter water as you drink. Two-stage filtration means that the activated carbon reduces taste and chemicals, while hollow fiber removes particulate, microplastics, and pathogens. Available at Schnee's, Uphill Pursuits, and Grizzly Outfitters; $40.
