What is an XXL hat size?
There’s no industry standard for XXL (also written 2XL); one brand’s XL is another’s XXL. At MONGO, XL–2XL means hat sizes 7½ to 8½, and the 2XL end is roughly 8 to 8½, or 25.1–26.7 inches around. Go by inches, not letters.
MONGO hats cover XL through 2XL in one adjustable hat: sizes 7½ to 8½, or 23.6–26.7 inches (60–68 cm). You don’t have to guess between two letter sizes. If you’re anywhere in that range, the snap gets you there.
XXL snapback hats that aren’t just stretched
A lot of “XXL” caps are a regular cap with a longer strap. The crown stays shallow, so the hat sits high. Ours have a deeper crown and wider band, so a 2XL head gets a 2XL hat.
- XL Performance Snapback 2.0 ($59.99) — structured deep-fit crown, flat brim, extended-range snapback, seven colors.
- XL Foam Trucker ($44.99) — foam front, mesh back, Black or Green/Black.
Soraya W.: “I am an 8 in traditional New Era sizing and even an 8 is slightly small.” That’s the kind of head these are for.

FAQ
It varies by brand. At MONGO, XL–2XL covers sizes 7½ to 8½, and the 2XL end is roughly 8 to 8½, about 25.1–26.7 in around. Always check inches.
Yes, they are two ways of writing the same size.
No. Each hat adjusts across XL–2XL, sizes 7½ to 8½, so one hat covers both.
Ours are. MONGO hats have a deeper crown than a standard snapback, not just a longer strap.
Above 26.7 in (68 cm) you are past our range, and a MONGO hat may feel snug. Measure first with the Hat Size Calculator.
Try it on indoors with the tags still on. If it’s not right, send it back unworn within 30 days for an exchange or refund, and MONGO covers the return shipping.
