The 16 oz PERK EvoVessel 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.
