How to use: Simply put on the jacket like you would any other outerwear. It's easy to slip on and off, even when you're in a hurry. Just make sure your hands pass through the cuffs comfortably. When you're done cycling, you can use the stuff sack to store it in your back pocket or saddle bag.
Things to note: Although it's waterproof, don't deliberately submerge it in water for a long time. The reflective details are for better visibility at night, but you still need to follow traffic rules.
Maintenance advice: Wash it in cold water with a mild detergent. Don't use bleach or harsh chemicals. Hang it to dry, and avoid direct sunlight to keep the color and fabric in good condition.
