Contigo may be your favorite brand of travel mug, but their water bottles are also pretty spot-on. I have the Ashland (which is only $10 right now) and I use it every day, and if you’re looking to upgrade your H2O intake, this $16 steel-bodided Autoseal Fit Trainer should be your answer. It has the classic Contigo autoseal technology, plus a button to make one-handed drinking easier.
