Toasty, Toastier, Toastiest Difference
The coats are all durable water resistant and designed to be perfect for harsh, snowy Northern States and Canada. Parents love them as far north as Alaska and the North Pole.
I do not provide temperature ratings as in general they are a bit of a marketing gimmick - most good companies like Patagonia don't either.
As a one Mama startup I make a promise to parents that's true - this coat is crash tested and designed to be safer than traditional coats and can also be used with the same harness setting as no coat at all without adjustments. I don't want to mix promises that are true with marketing terms that are debatable.
Toasty is our original design. Toastier and Toastiest provides more coverage for the neck and head against harsh, whipping winds. Toastiest has a cozy sherpa lining which is thicker and warmer.
Any choice will work wonderfully and your little love will be toasty warm and safely dressed for the car seat all at the same time!
