Baen Sendi Hydration Bladder
A hiker’s best friend Amazon

UPDATE: This deal is donezo, but it’s still available for $13.

Spring and summer are right around the corner, and with the changing of the seasons comes the blessed ability to be outside all day. During the hot months, $9 is a small price to pay to fend off dehydration. Whether you are a hiker, a biker, or a city stroller, having quick and easy access to drinking water is pretty important. (If you need a reminder, this is what happens to your body as it dehydrates.)

The Baen Sendi hydration bladder holds 2 liters of H2O—which is roughly the amount of water you should consume daily. The bladder is 14 inches by 7 inches (roughly) and made out of a BPA-free plastic (thermoplastic polyurethane, to be exact). There is a 3.54-inch opening, which makes it easy to clean, and the bite valve mouthpiece prevents leaking. For optimum performance and prevent damage, place the bladder in a backpack that will allow you to secure the water bladder in place.

Amazon; $9.
