I am willing to buy a something around a 20 degree UQ for my WBBB. I plan to use this here in colorado into the fall so I might even want something warmer than 20*. I believe I want something full length because my feet get cold easily. I use this for motocamping so I dont necessarily need something super light but I do need it to be super compact as I dont have much room left on my bike. Want something easy and quick to hang. Camo exterior would be preferable. If I dont find a used deal I plan to order a new HG Incubator 20*
