We're reducing our impact wherever we can. Our popular vacuum insulated TKWide Kanteens are now crafted from certified 90% post-consumer recycled 18/8 stainless steel! This change allows us to extend the life of raw materials and reduce their environmental impact, all while delivering the performance and durability you expect from these hardworking Kanteens. TKWides feature upgraded thermal performance with our TK Closure technology; rounded lip for a more comfortable drinking experience; and five interchangeable lids with slim profiles, easy-carry swivel loops, and a range of drinking styles - from chugging to sipping to flipping open a built-in straw. The combination of award-winning Climate Lock double-wall vacuum insulation and cutting-edge TK Closure takes thermal performance to a whole new level. We've replaced our traditional external thread closure system on our lids and bottles with a revolutionary internal thread design. This design creates a stronger insulated barrier inside your Kanteen. Use the loop cap on our TKWide to create an all stainless enclosure for optimum thermal performance. TK Closure coupled with Climate Lock vacuum insulation effectively traps heat or cold. Be careful when you take your first sip … drinks stay piping hot or icy cold for hours and hours. TKWide Kanteens are built to take a beating and still look good at the end of the day. Our chip-resistant Klean Coat finish is not only four times more durable, but also exceeds regulatory standards for human and environmental safety. Go ahead, bang your TKWide on boulders in your favorite trout stream, toss it in your commuter bag, stash it ramp-side at the skatepark. You might get banged up, but your Kanteen won't.
