We replaced a stamoid full flybridge enclosure that was 9 years old and had been restitched once. Boat resides on the Chesapeake, so not the intense sun of South Florida. The fabric was still serviceable but the stiching holes leaked a bunch and the eisenglas was brittle and cracking. We chose stamoid again because we felt nine years was pretty good service and the canvas shop talked us into stratoglas. I bit pricey, but two years in and we are very pleased. We also chose white to lessen heat gain and fabric fading. Steve P
