Geigerrig’s Hydration Pack bladder, which comes standard in the brand’s hiking and biking packs (from $90), can be pressurized with a simple pump, so you can drink without sucking. Or squirt it into your dog’s mouth. Or clean out a wound. Or ... you get the picture.
Platypus Big Zip SL
The Platypus Big Zip SL was the most secure (read: no accidental leakage) zip-top bladder we tested—and its giant opening made it one of the easiest to clean and dry.
Hydrapak attacked the age-old problem of water sloshing around annoyingly in your bladder with its Shape-Shift reservoir. Zip it up in the middle to create a more dispersed load, or unzip it to max out the amount of water you carry.
