Real Simple magazine chose the PERK as one of “Six Smart Products to Make Your Life Easier”. The 16 oz PERK 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 is designed for one-handed use, with a push button that opens the top, and a lock to keep your drink leak-free. 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 through the day. Color: Black.
