The Swig 30 oz Mega Mug has entered the chat. This straw tumbler mug stands out from the Stanley’s and Trek’s with triple insulated stainless steel that will keep your drink, and even the ice, cold for 24 hours. The silicone flexi tip straw has a sturdy plastic base for when you're digging through the ice for those last few drops of cold brew. We know all of you water girlies will be taking this with you everywhere, which is why the base is super cupholder friendly and the handle has a comfort grip. Designed for the chaotic and the clumsy, this tumbler is nonbreakable, slip-free, scratch-free and noise-free silicone base.
