Rasta tams made from pure Australian wool will last a long time if cared for properly. This wool tam is a quality product and has to be washed by hand with gentle soap in luke warm water. Then rinsed three times and laid flat to dry. This is important as the wool reacts to hot and cold water and retracts. Wool can hold many times its weight in moisture so will keep the rain off your hat if you get caught out. It will also keep you cool in winter. These hats come in one size fits all and you can thread a piece of elastic through the top to make it stay on your head. Great for long dreadlocks.
