Real Simple magazine chose the PERK as one of “Six Smart Products to Make Your Life Easierâ€. 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.
