OUR TAKE Many insulated vessels will keep contents hot for hours—that is, until you take the lid off. Klean Kanteen has solved that problem with the TKPro. (The TK stands for Thermal Kanteen.) Double-wall insulated stainless steel is par for the course, but a unique threaded lid doesn’t need to be unscrewed all the way to pour, so your hot drinks stay hot even longer. (We pegged it at 30 hours, longer than the competition). Bonus: You can pour from the TKPro at any angle. Price is average compared to other double-wall bottles. The downside: It’s heavy, even for its category.
TRAIL CRED “We took the TKPro on a multi-week road trip through the Pacific Northwest and put it through the wringer,” one tester says. “It tumbled around in the back of our truck without damage and kept our camp coffee piping hot while we were on an all-day hike in the North Cascades.”
