The CONCEPT Radiator Zipperless uses Polartec Delta fabric across the front and shoulders of the jersey, actively cooling and wicking moisture more effectively than wearing nothing at all. No need for the extra bulk and seams of a zipper.

CONCEPT starts at the highest levels of the sport, with feedback, testing, and customization for the fastest athletes in gravel as a complete skinsuit. It's a testing ground for new technologies and faster designs, before becoming a reality in the CONCEPT collection.

CONCEPT is more than a product. It's an ambition to see what's possible — made to marry the absolute best materials available with a zero-compromises design. The CONCEPT Radiator Zipperless Jersey is our fastest jersey, that effectively wicks moisture on the hottest days, so it's cooler than wearing no jersey at all.

Product care

Caring for your cycling gear properly will extend its life and maintain its performance, fit and quality. It’s important to consider these instructions carefully. While we stand behind the quality of our apparel, not adhering to these instructions will void our warranty against manufacturing & defects.

  • We strongly recommend washing your new gear before wearing it. You’ll find that your apparel will soften, and fit & comfort will improve after washing - especially with bibs & shorts.
  • Machine wash cool, 86°F (30°C) with like colors: Cooler temps maintain better longevity for your apparel. Like colors, especially lights, will remain more vibrant when washed with like colors.
  • Use mild detergent. Do not bleach or dry clean: Strong detergents & bleach can break down the fibers and elastane in the garment, dramatically reducing its life.
  • Close all fastenings: this goes also for other garments mixed in with your cycling apparel. Velcro closures or clasps can catch on stitching or trim and damage your garments.
  • Lay flat to dry. Do not tumble dry: Do not put your cycling apparel in the dryer. Even on low heat. Don’t do it. Heat can damage fabric, elastic and heat transfer logos very easily. Lycra (Elastane) is used throughout our garments to provide compression and support and is susceptible to damage from heat and can irreparably damage your apparel.
