Trek Tumbler

Filled this up with ice water before a long hike and it was still cold hours later when I finally cracked the straw lid, which is nice and tight so nothing leaked in my bag. The 50oz size meant I only had to refill once all day, which was honestly the best part for me.

I was skeptical about the double wall insulation, but my coffee stayed piping hot during a three-hour morning hike. The straw lid is also snug enough that I can toss it in my bag without worrying about leaks.

The 50oz capacity is a game changer for my long hikes, and the straw lid really does prevent leaks in my bag. Coffee stays hot for hours, so I can actually enjoy it at the summit.
