You'll find that your apparel will soften, and fit & comfort will improve after washing - especially with bibs & shorts. - Machine wash cool, 86F (30C) 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.
