The Baby Puff Mittens from Patagonia (retails for $45)  bright orange, 18-24 month size. My son was too big for them by the time he was 2 but my daughter could put them on until 3.

We wear them only occasionally (I never quite got the hang of pulling them all the way on without my kid fighting it). They are in good used condition, clean, no wear or tears (see pictures the cuffs are in good shape).

These Patagonia fabrics do change appearance slightly after washing so they don't look totally new, but good shape lots of use yet!
