Regarding the Big Agnes Clearview Air Pad - Mummy--Item #BAG0129:
What's the best repair kit for this material?
Big Agnes makes a repair kit for their sleeping pads. I don't know if it is best or not for whatever type of leak you have but it should do the job pretty well.
The glue from our repair kit works. We have also found that Tear Aid Type A patches work really well for the Polyurethane material. Tear Aid is the brand and you want to be sure to get Type A patches.
The repair patches for the Platypus hydration bladders work, too.
