I got the flannel-lined cotton one (indoor only) from Rick (Sunbeam Specialties)… great fit and supports the team that helps us keep these things on the road. Mine still looks good after 30 years.

I have an all-weather cover (for travelling) from CA Car Cover… I have had good success with them for other cars, but the one for the Tiger had to go back for re-work (was too short on sides).

Good luck.
