The YETI Rambler 30oz Travel Straw Mug is a large stainless steel travel mug that carries a big pour into a tote or duffel, since the quick-flip straw lid stays leakproof while closed. A welded, easy-grip handle makes the mug simple to haul, and the lid sits in several positions to suit left- and right-handed sippers. What Our Gearhead(R) Experts Are Saying:"This mug slides into my car's cup holder, and I flip the straw open and sip without lifting it out. Having that much water in reach on a long drive is why it rides along with me."
