Spring is round with us. It is the best season of a year. Why not invite a few friends for biking and flying kite? It's sometimes still chilly you'd better put your jacket in the waterproof backpack for fear of an unexpected rain as well as you can take some yummy snack. Thus a dry bag seems necessary. You can put the snack in the dry bag as well as your biking gloves, cell phones, wallets and so on.

Let's go for outdoors!
