Coffee's loyal commuter. The It Fits Travel Mug is an 18oz insulated stainless steel mug that — yes, really — actually fits in every car cup holder. This PURE Pristine mug brings a fully 18-8 stainless steel build, double-wall vacuum insulation with a thermal copper lining, and our patented SiSA™ antimicrobial coating. SiSA™ uses the natural antimicrobial properties of silver — not chemical additives — to eliminate 99% of microbes on the drinkware's surface. The twist-on lid with flip-top opening is splash-proof and leak-proof, so your morning brew stays in the mug (not on the dashboard). Holds heat up to 8 hours and cold up to 36, BPA-free for daily-driver peace of mind.
