Yeti has long set the standard in rugged, reliable drinkware. The Rambler line, in particular, has earned a loyal following for its exceptional insulation and durable construction, and we’ve considered it the best upgrade travel mug for years.
Yet, for all of the strengths of the insulated stainless steel vessels’ design and construction, almost every model has shared one consistent weakness.
Most, if not every, version is liable to leak if used in challenging ways.

But now, through a pair of new releases, Yeti is claiming it’s finally solved this issue once and for all, and can finally offer Rambler owners a drinking vessel that’s “100% leakproof” in the outfitter’s own words.
The Retrofit Solution

The key innovation revolves around Yeti’s new Rambler Commuter Cap. It’s a streamlined, user-first lid that consists of two parts that together bring convenience and peace of mind to Yeti’s Rambler bottle ecosystem.
