These bibs have been a game changer for working the farm. They are completely waterproof in the rain and washing down pigs. Keeps our clothes dry and clean, no longer need to do a nightly load of farm clothes in the wash. My son hates the feeling of wet animal hair on his legs, these bibs have been amazing for him. They are slightly warm on hot days, but overall light weight and tolerable in the heat. We will be adding jackets to the collection!
