01
SealSlide™
Sealed. Actually sealed.
Magnetic sliding lid completely covers the straw. Bag-proof, upside-down-proof. Leakproof by design, not by claim. Torture-tested: 500 open-close cycles, upside down in a bag, zero drops.
02
CleanSplit™
The straw you can actually clean.
Splits open lengthwise, wipe it in 2 seconds, snap it shut. No brushes, no hidden gunk, no mold. Nobody else makes a straw you can open flat. This is a first.
03
PureCore™
Coffee Monday. Water Tuesday. Zero ghost flavors.
Ceramic-lined interior so smooth nothing sticks. No metal taste, no stains, no smells. Two years of daily use and your water still tastes like water.
04
FrostCore™
24 hours of ice. 12 of heat.
Double-wall vacuum insulation in 18/8 stainless steel. One fill lasts all day. Ice at 8am, still there at midnight.
05
Tool-free everything.
The lid pulls apart into 3 pieces by hand, gaskets pop out, grip sleeve included in the box. Built to be owned for years, not replaced. Nothing on this cup can trap water, hide dirt, or grow anything.
06
TwinLid™
Two lids. Zero compromise.
Hot mornings, cold afternoons. One cup does both: flip lid for coffee, straw lid for ice. Both lids are in the box, nothing sold separately.
