Introducing the ultimate adventurer's companion - the original collapsible bottle! The revolutionary spiral design not only lets you squash it down for easy packing, but it's also an eco-warrior, reducing its carbon footprint during shipping. Crafted for the wild at heart, this bottle is your ticket to plastic-free freedom. BPA and toxin-free, it's as clean as mountain air. Plus, it's a featherweight champion, so you can lug it around without feeling like you're carrying a boulder. With a wide mouth big enough for ice cubes, your drinks stay refreshingly cool, while its odor-resistant feature keeps them tasting pure as a mountain stream. And fear not, clumsy adventurers - it's leakproof and shockproof, ready to take on even the roughest terrains. From sizzling deserts to icy peaks, this bottle can handle the heat - literally. It's resistant up to a scorching 400F, so you can enjoy your hot brew without melting your gear. Clean-up? A breeze. Toss it in the dishwasher, and it's good to go for your next adventure. Crafted from top-notch materials - 100% food-grade silicone for the bottle and 18/8 stainless steel for the cap - this bottle is built to last. In its compact form, it's a pocket-sized 4.8 inches, holding a respectable 8 fluid ounces. But when fully expanded, it stands tall at 8.4 inches, accommodating a generous 20 fluid ounces. Adventure awaits - and with our collapsible bottle by your side, you're ready for anything nature throws your way.
