I did a thru back in 2012 and I used a Granite Gear Blaze 60, which I love and still have. I recently moved to an area where I'm in the middle of a camper's/hiker's paradise (Fort Carson, CO) and I brought it along with me even though I haven't used it since. One problem is when I was at the hostel in Bangor I was doing laundry and I foolishly washed and dried (along with other things) the foam pad that Granite Gear puts in between the plastic frame and your back:

When it came out of the drier it was melted and misshapen and unusable, so I threw it out. When I got home I emailed Granite Gear and asked them if they sold replacements, which they do not. I love this pack and I was wondering if anyone knows of any aftermarket foam pads or any bright ideas for a material I could use as a replacement. I've thought about using my neoair sleeping pad semi-inflated but I also wanted to put this question out there. Thanks!
