I tried to prove my Coldest wasn't the best bottle out there… it did not go well for me 😅🧊 Triple insulated so it stays cold for 36 hours and warm for 13+, it's 100% leakproof, it fits 99% of car cupholders, and it's stainless steel and heavy-metal tested. Tell me what you'd test it on next 👇 #coldest #coldestwater #waterbottle #hydration #skit
