Priority Bicycles has provided a $20 off coupon code to KevCentral viewers. The code is only good until January 25, 2019, so use it while you can. This is a great deal on a super helmet!
Code: KEVSTACK
Link: https://www.prioritybicycles.com/products/stack-folding-helmet
Just enter this during checkout and it will automatically remove $20 from the cost of the helmet.
This looks like something Devo would wear while biking.
