The Avex Brazos Autoseal Stainless is a .7 L, insulated water bottle with a unique lid design. The lid makes drinking with one hand easy with its push-button function to allow the drinker to regulate the amount of water let out of the mouth of the bottle. We were pleasantly surprised by the Brazos and found this drinking mechanism to be the most effective of all the one-handed drinking solutions provided in the water bottles we tested this year.
Straws, like those used by the Camelbak eddy or the Citrus Zinger got dirty, while the Klean Kanteen Classic sport cap leaked accidentally if it was not securely closed. But the Brazos Autoseal function worked great; it was both leakproof and clean. Its insulated feature makes it great for hot or cold liquids and its small size allows it to toe the line between a to-go mug and a water bottle. This versatility is a nice feature for a small bottle.
