Why Coldest Bottles Fit Cirkul Lids
Cirkul lids are designed for standard wide-mouth bottle openings — the same opening spec the entire Coldest Limitless Tumbler lineup is built around. Every bottle below uses the universal wide-mouth thread pattern that Cirkul's flavor cartridge lid screws directly onto, with no adapter required. Unscrew your Coldest lid, twist on your Cirkul cap, and you're done. The triple-wall vacuum-insulated stainless body keeps your flavored water ice-cold for 36+ hours, while the leakproof seal works just as well with the Cirkul cap as it does with the original.
Choose any size below — 15 oz, 24 oz, 36 oz, or 46 oz — and you'll get the same Cirkul-ready wide-mouth opening, the same insulation, and the same lifetime warranty. Pick the capacity that matches your hydration goal; the fit is identical across the line.

Cirkul Lid Compatibility — FAQ
Do all Coldest Limitless Tumblers fit Cirkul lids?
Yes. The 15 oz, 24 oz, 36 oz, and 46 oz Coldest Limitless Tumblers all use the same wide-mouth thread pattern. The Cirkul flavor cartridge lid screws directly on top of any of them with no adapter needed.
Will the bottle still be leakproof with a Cirkul lid?
Leakproof performance with the Cirkul lid depends on Cirkul's own seal, but the Coldest bottle threads are precision-machined and seat the Cirkul cap firmly. Most customers report identical leakproof performance as with our original Coldest lid.
Which Coldest size is best for daily Cirkul use?
Most Cirkul fans prefer the 36 oz for a full day of flavored hydration without refilling. The 46 oz is ideal for workouts or long shifts, while the 15 oz and 24 oz are perfect for kids, commutes, and shorter days.
Do I need to buy a Cirkul lid separately?
Yes — Cirkul lids and flavor cartridges are sold by Cirkul directly. Your Coldest bottle ships with our standard insulated lid and straw; the Cirkul lid is an aftermarket swap that twists right on.
Does using a Cirkul lid void the Coldest warranty?
No. Your Coldest lifetime warranty covers the bottle body. Using a third-party lid like Cirkul's does not affect coverage on the Coldest bottle itself.
