Mitchell Design is proud to have worked with Bulk™, the amazing fitness nutrition company.

Last year I was contacted by Bulk to build them a fitness apparel collection that would represent the brand.

Here are a few images from the design process and some of the finished articles.

If you need help with the design and manufacturing of your fitness brand, get in touch for a free consultation.
