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. 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. Do not bleach or dry clean. Strong detergents & bleach can break down the fibers and elastane in the garment, dramatically reducing its life. 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.
