I know what you’re probably thinking: Karina, aren’t those for hiking and doing outdoorsy things? Wrong. Now, I should preface this review by saying that I drink a ton of water — in the before times, I was constantly refilling my bottle and going to the bathroom (but not so much that I wasn’t getting work done, obviously). But after seeing how hydration is key for healthier skin, more energy, and generally keeping in tip-top shape, I couldn’t go back to the always-a-little-dehydrated lyfe. While I first discovered the joys of hydration packs as I got into hiking, I’ve found they’re not just a convenient way to always have water readily available — dare I say they’re kind of … cool?
