can you customize this hat Like put a logo on it and write somthing???

Dear, this is MUTECOMPANY Inc. First of all, thank you for your interest in our product. Please understand that customization is difficult because this product is made in bulk. Thank you.

Does this hat come in black? I see a black one in pictures but I cannot find a link to it on Amazon.

Dear, we're MUTECOMPANY Co., Ltd. First of all, thank you for your interest in our brand UNDERCONTROL. Currently, in the case of black color, we have sent to AMAZON logistics center, but it seems that it has not arrived at the warehouse yet due to the concentration period of Black Friday logistics. It is expected to be in stock during this month and can be purchased. Thank you.

Will this fit a siz 7 3/4

Hello. We sincerely apologize for the delay in confirming our inquiry. The size of the product you inquired about is adjustable with the back strap, but We think it will be a little smaller than the size you mentioned. Thank you.

Will this fit a size 8in head?

Dear First of all, thank you for your interest in our brand's products. In the case of this product, the size can be adjusted by the strap on the back, but because of the fabric's feature that doesn't stretch, the depth is shallow, so We doesn't think it will be recommended if you have size 8. Thank you.
