YETI Rambler 18 oz Water Bottle with Chug Cap review

The YETI Rambler 18 oz Water Bottle with Chug Cap ranks fifth: it is well built and well supported, but YETI publishes less than its rivals about how long it keeps drinks cold. The bottle is double-wall vacuum insulated stainless steel, comes with the Chug Cap, and YETI calls it 100% leakproof. The spout is shatter-resistant and dishwasher safe, the bottle fits most cupholders, and YETI lists free returns and a 5-year warranty on the page. You can swap in the Flip Chug Cap or the Straw Cap for $15 each. It costs $32. The trade-offs: the page we read gives no hours-cold or hours-hot figure, unlike Hydro Flask, CamelBak and Klean Kanteen, 18 oz is the smallest insulated fill here, and YETI warns against carbonated drinks or contents above 185°F with this cap. We compared documented features and published prices and did not test the bottle.
