The Avenel Benni Foam Strip Hat Size Reducer offers a practical solution for achieving the perfect fit. This three-pack features soft foam strips with adhesive backing that reduce hat circumference by up to one full size, accommodating variations in head shape and seasonal layering. Simply apply the strips inside your hat's crown for immediate customization without altering the hat's exterior appearance or structure. The cushioned foam provides additional comfort during extended wear whilst maintaining stability throughout the day. Ideal for refining fit on inherited hats, compensating for shrinkage, or adapting headwear across different seasons, these reusable strips deliver reliable sizing adjustment for your existing collection.
