The design is a copy of my Rofco B40 oven. In this oven I've baked nearly 10,000 boules, baguettes, cookies, and the occasional pizza. The oven has a cult following among micro bakeries and you can tell because it takes 6-9 months to have them made and shipped from Belgium.
The t-shirt is 100% cotton. The hoodie is 80% cotton 20% polyester blend. The design was created by Justin Bryan Nelson and screen printed by Nick at Squija Screen Printing.
