So after reading your post I remembered I had an old Wild2 sitting in my garage that had a pretty bad hole in it. So I emailed them and this was the response I got. Not really a surprise as the Wild series has been gone a while now.
Al,
Thank you for contacting Otter Outdoors!
Yes, you could order a new canvas but you would also need to order new framework for fitment purposes.
Unfortunately, by the time you order these pieces you are close to the cost of an entirely new package.
In most of these situations we recommend selling your current one and purchasing new. This is the most cost effective for you.
Let me know if you have other questions!
