DetailsThe 16 oz PERK insulated travel mug is the perfect portable container for hot and cold brew tea or iced and loose leaf tea, since a convenient strainer is included. It features our signature TriMax® Triple Insulation and keeps drinks cold up to 36 hours and hot up to 8 hours. The PERK tea and coffee mug is designed for one-handed use, with a push button that opens the top, and a lock to keep your drink leak-free. Plus, choosing a reusable tumbler cuts down on single-use plastic consumption. Keep this versatile travel mug in your car cup holder or toss it into a tote and bring it to yoga class, on the trails, or to work to stay healthily hydrated throughout the day. The PERK is available in both 16 oz and 20 oz sizes.
