Thought I'd bring it up 'cause I know there are other Outcast owners out there.
I've had my Fishcat Deluxe for a while now, and have been battling slow leaks everywhere. On one of my last trips, the D-lux, finally gave up. So I gave Outcast a call, and even though my warranty period was probably past, they sent me all four bladders.
Their products are top notch, and so is their customer service. I wouldn't hesitate to buy one of their products again. So if you've got some leaky bladders of the inflatable kind, I've give Outcast a call to see if they can help you.
