Our Bouffant scrub cap is machine washable and dryable.  We Pre-wash all of our fabric in hot water and dry on a high heat setting to pre-shrink.  After this pre-shrinking, we iron the fabric, cut each cap out and begin the sewing process. As with any 100% cotton fabric there may be additional shrinking.  Wash And dry on the lowest temperature setting you can to minimize shrinking and extend the life of your cap.
