What Our Gearhead(R) Experts Are Saying: "I use this insulated 2L bladder in my winter hip pack and during summer bikepacking trips. The hose stays frost-free longer and the push-lock bite valve makes it easy to use even with gloves. Solid flow, no leaks, and no bad taste."From mid-summer slogs to frosty alpine descents, the EVOC Hydration Bladder 2L Insulated keeps our water flowing no matter the conditions. Designed for compatibility with hip packs and hydration systems, this bladder features a thermal-insulated hose to resist freezing in the cold and overheating in the sun. The wide SLIDE SEAL top closure makes refills fast and leak-free, while the PLUG-N-PLAY connection lets us detach the hose in seconds-ideal for mid-ride pack swaps or quick cleanups post-ride. Free of BPA and PVC, the bladder delivers clean-tasting hydration we can trust for big days on the trail, gravel, or snow.
