Whether working in the field, at the playground with his kids, or airport hopping, Jon knows that clean H20 is the foundation for all life. Our top glass bottle, the Purifyou Premium, has a relatively slender design (although it doesn't fit in most cup holders) and a silicone sleeve that makes it easy to grab.

It is especially important to clean your bladder often if you use sports drinks, sugared juice, or water. For example, one particular bottle passed the controlled test with flying colors but then leaked its contents into our bag and ruined two headlamps.The magnet next to the bite valve securely attaches to your backpack strap (if designed for this use). Our field of testing included long commutes, longer work days, short day hikes, windy bike rides, and even fun time at the park with our kids. separated them somewhat into categories, the overall review objectively compares bottles of all different types side-by-side. A noteworthy consideration is that the charcoal filter in this bottle doesn't remove bacteria, viruses, protozoa, or heavy metals.

The flip-up straw design on the lid makes for quick and easy sips that we found promoted our hydration.

The durable plastic cap has an ergonomic carry handle with a carabiner-like clip, making it easy to lug around. Despite the extra twisting, all these bottles have their specific features and uses, so it's good to note that they won't leak on you. The Lifestraw Go is a cheaper type of plastic; when drinking directly from the bottle (with the lid off), we could definitely taste it. It takes only a few seconds to unscrew the cap, fill it with water, re-screw the cap, and be able to start drinking. This is an inherent design flaw in this otherwise very useful filter press that we were happy to have with us on several occasions despite the added weight.
