Urban Baby Bonnet (UB2) Sizing
What size should I choose?
Each of hat style fit slightly differently, and therefore, they do have slightly different sizing recommendations. See below by hat style, and we've done our best to help you decide what size is correct. In EVERY case, though, the best way to know what size to order is to MEASURE your child's head circumference. We offer age ranges as a rough guideline but head shapes vary and children, even when "big" or "small" for their age can have widely varying head sizes. Age is NOT a reliable predictor.
Bonnets tend to run LARGE. Except for the XXS which is designed to *actually* fit newborns, if in doubt, size down. Our XL bonnet is HUGE and is ONLY for children whose head circumference is above 21".
skiBonnets run small. Sizing up is advisable if your child is at the end of the size range. The fleece tends to be thick and while we prefer a very snug winter hat (no wind!), not everyone does. If you're in doubt, size up.
These run true to size. If in doubt, size UP.
* Brimless bonnets--
These run true-to-size. If in doubt, size UP.
Spring/summer caps tend to run true-to-size or a tad large. They are designed to fit all the way down on the head, so the edge of the cap is at about the bottom of the ear lobe. The hats are designed this way so they provide full sun protection for the entire ear.
The caps will appear TOO TALL if you're looking for an above-the-ear fit.
The caps fit best when worn at an angle, with the elasticized back down below the bulb of the head and the brim up just below the hairline.
If in doubt, size UP.
skiCaps run SMALL. If your child is towards the end of the size range and you do not want a snug fit (snug fits are great for wind protection), then please size UP.
Our pixie hats run LARGE. They can be folded back even at the snap point for a smaller and shallower fit. Stay within the size range or if you're in doubt, size DOWN.
* Pilots & Ear Hats--
Pilots and ear hats use the same pattern. They tend to run LARGE. If in doubt, size down.
