The 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 the 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.
