Klean Kanteen Classic 27oz With Flip Seal - 800 ml Capacity

Klean Kanteen Classic 27oz with Flip Seal Sport Cap is a single-wall stainless steel bottle built around a 27-fluid-ounce capacity. The bottle measures 10.75 inches high by 3.41 inches wide and weighs 8.4 ounces with its cap and included straw.

Capacity And Construction

The bottle's stated capacity is 27 fluid ounces, or 800 ml. Its body uses certified 90% post-consumer recycled 18/8 stainless steel, while the Klean Coat finish is designed to resist chips.

Klean Kanteen lists the bottle at 8.4 ounces, or 238.1 grams, and gives its dimensions as 10.75 inches high by 3.41 inches wide. The opening measures 1.75 inches, or 44 mm.

Cap And Daily Handling

The Flip Seal Sport Cap is described as 100% leakproof and includes an ergonomic spout. The included stainless steel straw is removable, so the cap can be used with or without it.

The Classic 27oz model is non-insulated, unlike Klean Kanteen's insulated Classic bottles. Its single-wall construction keeps the bottle lighter than a comparable double-wall design, but it does not provide the same temperature-retention format.

Klean Kanteen lists the bottle as dishwasher safe, BPA-free, lead-free, cupholder friendly, and compatible with cold and room-temperature drinks. The cap carries a child-safety warning for children 3 and under.

Price And Category Context

US pricing places the bottle at $21.95 as of 09/24/2026. Target lists the same 27-ounce Flip Seal Sport Cap bottle at $21.95, while Klean Kanteen's own US listing shows the same price for the standard finish.

Compared with a narrow-mouth insulated bottle, the Classic 27oz trades temperature retention for lower stated weight and a simpler single-wall design. Compared with older Sport Cap versions, the Flip Seal configuration adds a removable stainless steel straw and a cap designed around a thumb-operated seal.

Best Fit For The Format

The Klean Kanteen Classic 27oz with Flip Seal Sport Cap fits users who want a reusable stainless steel bottle with an 800-ml capacity, a narrow profile, and a removable straw. Its 10.75-inch height and non-insulated construction suit cold or room-temperature drinks rather than hot-drink storage.

The category placement is straightforward: this is a single-wall stainless steel water bottle, not an insulated tumbler or a thermal flask. Its useful specifications are the 27-fluid-ounce capacity, 8.4-ounce stated weight, 1.75-inch opening, and $21.95 US price.
