YETI combined the classic pour over shape with their stainless steel insulation to give you an ultra-durable base camp brewer. It fits any V60 filter and works seamlessly with your existing Rambler Drinkware for backcountry blooms and first light roasts. All Rambler Drinkware is compatible with the Rambler Pour Over, though YETI recommends the Rambler 20 oz Tumbler as the largest size due to the amount of coffee brewed.
