Brilliant: MSR Thru-Link Water Filter + Bladder = Easy Peasy HydrationSure, you can screw a Sawyer Mini onto a Platypus water bottle, or use a Lifestraw to drink right from a creek, but there’s something so easy and simple about a hydration bladder that a water filter that attaches to a bladder’s drink tube is about as good as it gets. And that’s MSR’s Thru-Link filter. It clips easily onto most hydration bladders, so there’s no need to cut tubes and futz with finicky adapters, like you’ll deal with if you try this with most inline filters. MSR designed this one specifically for hydration bladders and it works perfectly. I use the Patagonia Nine Trails hip pack when riding, and clip the Thru-Link onto the pack’s included bladder.
