Ive had a Big Sky 2 person tent for a couple of years now. I’ve had it in enough heavy rain to know that it is waterproof. My question is how do they do it? I’m pleased, impressed and curious.

It has external poles and nearly 2 dozen penetrations through the fly. I can’t find anything that looks like seam sealing compound or taped seams. Could the waterproofness mostly be a product of the way it is designed and sewn? The write up says that any seam sealing required is done inn the factory.

If they have not used tape there that is impressive- that bugger has never let water in anywhere. Top tent.

I think their tents are waterproof because of how the seams are sewn. The main seams are all bounded with silnylon. I sold my Chinook a couple years ago but recently bought a 1P Revolution with solid fabric inner – it’s sewn the same way.

Thanks for the link to the old post. I forgot about it, even though it was the reason I bought the tent.
Can’t believe that post and my purchase of the tent was 4 years ago. Time flies.
My model includes the inner solid inner tent (warmer) and the cross pole overhanging porches on both sides (allows open doors in most rains and dry exit/entry). Fly extends well beyond the tent so no problem with splashing of mud and rain on tent on ends. Tent is noticeably bigger than my MSR Hubba Hubba HP. Foam pads of my wife and I overlap in MSR. There is space between pads in the Revolution.
Even with all these features the fly, tent and poles still weigh only about 3.5 lbs (if I recall correctly).
Cross pole that supports the two front porches crosses the main X poles at a point below the cross point of the X poles. So the cross pole is supported at two locations (two poles) rather than the one point of support at the apex of the MSR poles. Feels much stronger than the single point of support of the MSR tent.
Overall this is the best of the 2 dozen or so tents I’ve purchased during my life. A slightly larger zippered window would make kit more comfortable on a warm (80 degree F) night but that’s about all I can think of in terms of improvement suggestions.
Sep 25, 2019 at 2:44 am #3611621I asked the same question many years ago face to face to the founder of Big Sky. I vaguely remembered the answer was “this is something secret”. :-)

“this is something secret”
I don’t blame him.
