A couple weeks ago I picked up an Explorer Ultralight off the first round to replace my Expedition. And, this morning I ordered up a Super Shelter #2 to go with it. I have a SS for my Expedition and was pleased with it's performance last winter (if you can really call that a winter). I think my KAQ would probably go colder and maybe this winter I can really put them both to a comparison test. Anyway, I did find myself carrying the SS year round for general all weather use during the occasional thunder storm and cool windy mountain top night so I know I will want and use one for the Explorer.
