Protect & Repair Crown Inserts with Adhesive Backing

Premium Patch Adhesive Crown Repair Inserts For Panama Straw Hats.

The easiest and most affordable way to protect your prized hat. If you have owned a straw hat for long enough, you've probably discovered that over time the crown of the hat can begin to crack. This can be from frequent pinching (which you shouldn't do) or from simple wear and tear. At Ultrafino we've known for a while that this issue can cause some heartbreak, imagine having your thousand dollar Montecristi crack, so we designed what we believe to be the best crown inserts to either protect and prevent the straw from cracking or if it has already cracked, to patch and prevent further cracking.

Made with a premium adhesive backing, just peel and stick into the inner crown of any straw or Panama hat. The adhesive we have chosen to use is formulated to last a long time and not leave behind any adhesive if you chose to remove it. This is perfect for prized collectors' hats if you ever choose to resell or gift them.

Please note: These insert strips do not contain any stiffener, which is great if you are sensitive to stiffening chemicals. However, if you are looking to also stiffen the crown please see our other crown repair strips that do contain water-activated stiffener.

3 Inserts included per unit.

Works nicely

(note: was offered a coupon for an honest review)
My hat isn't cracked yet, but it was just starting to show signs of developing one on one side of the crown. This patch strip went in easily (a bit of fiddlin', but not bad) and looks like it will provide a nice reinforcement that should keep any cracking at bay. Note also that the patch has a 3M film backing, so you do lose a little breathe-ability when putting these in.
