Made to order - Allow 1 to 2 weeks fulfillment time.

For quite some time now, we have been tinkering with the idea of customizing one of our Biltwell Gringo helmets. We finally did it.

A limited number of helmets are going to be hand-painted by our local artist here in Los Angeles, California.

The helmet’s design was inspired by our brand’s motto of “Nulla Dies Sine Linea”, which translates to “draw a line every day”. In essence, the implied message is to do something creative every day, even on a small scale. To showcase our motto in a visual way we came up with the depicted design. A set of horizontal lines that partially run across the helmet. The lines do not run across the whole helmet simply because there will always be more time to “draw the additional line”.


What comes in the box:

- 1 Custom Hand-Painted Biltwell Gringo ECE Helmet

- 1  Knox Maska

Helmet Fitment

Consider Sizing Up. The new ECE version fits much more tighter than the old DOT version. Please follow the instructions on our sizing chart.
