Our new Tyvek® rain hats are durable, lightweight, breathable and water repellent. Tyvek® is a unique non woven material designed to perform in harsh, rugged and extreme conditions. Tyvek® can resist repeated folding and flexing without tearing. A chin tie with cordlock and safety breakaway clip will keep it on your head on the stormiest of days. Roll it up and flip the decorative elastic loop around it to keep it compactly in your bag for an unexpected rain shower. Elastic loop, underbrim and chin tie are a contrasting white.
