New ways to carry your water.
My water bottle collection resides in an overstocked cupboard. The Hydrapak Stash Collapsible solves my storage problem. Emptied, the bottle collapses to a stackable two-inch tall disc that weighs roughly two ounces. To fill, simply unhook two tabs that cinch the molded plastic top and base together, then twist. It’s easier than opening a childproof bottle. The filled 750ml bottle is soft-walled but freestanding, with a handy webbing loop for carrying. I pack the Stash for hikes, travel, and whenever I need to stay hydrated but conserve space—which is daily. $18; hydrapak.com
When I mountain bike or trail run, I like to leave a chilled recovery drink parked at the trailhead. In winter I opt for hot tea. Enter the Hydro Flask 32 oz Wide Mouth. The company says that their double wall vacuum design keeps hot beverages hot for six hours and cold drinks cold for 12. Both claims held true in my field tests. After six hours in full Colorado sun, the exterior of the 14.1 ounce stainless steel bottle was warm to touch, but the contents remained refreshingly crisp. $34; hydroflask.com —Olivia Dwyer
