I have had a Kifaru Paratipi, six-man tipi, eight-man tipi, Longhunter Rendevous pack, various accessories and items of clothing plus a Siwash pack. I encountered some minor QC issues and the LHR simply would not carry as I needed it to, anything over 70 lbs. was very unpleasant. I have been carrying packs since 1956, btw, and have owned/used about everything out there.
I found the Paratipi a pita to erect in windy conditions with frozen ground here in BC, the six-man too low to comfotably walk around and the eight-man plus mossy netting, liner and large stove really suits me and is a part of my basic wilderness fly-in hunting camp. We will be taking this to northern BC in about a month as my buddy has a Grizzly draw.
This is expensive gear, they are quite good about exchanges and customer satisfaction, however, they can be totally off in their promised time for delivery of your order and you PAY "up front" in full on your credit card, which you DO NOT do with Mystery Ranch or Integral Designs when you order as they charge when they ship.
All in all, I like the Kifaru big tipis, there are better options for their smaller shelters, which are over-priced and the best gear they make seems to be their military models. I much prefer Mystery Ranch packs and also Hilleberg tents, but, Kifaru fills a niche that nothing else does.
BTW, their T shirts, hoodies and so on are excellent and I intend to buy more of these as mine are 4 years old, worn constantly and still in good shape.
