Review on 💧 TETON Sports Hydration Bladder: BPA-Free Water Reservoir for Easy Refilling and Cleaning by Eric Mueller

Warning: not yet used for hiking. I received them recently and, according to experience, often collected them and checked them for leaks, then filled them with water and left them on the table for several hours. bought was a leak. upset? Not much but I was aware of the risk based on other reviews but the price was worth the risk. Luckily I'm in the return/replacement window to get a new set. I keep the ones that don't expire and bring back the ones that do. Revain's easy return process justifies the risk at a low cost. However, buy enough in advance to test the hardware and be able to request a replacement if needed. Update (2019-08-13): A few times now and haven't had any issues with it. No leaks and easy water supply. My son and I had no problems with it. So make sure they don't leak before you use them and you'll be fine.
