I bought the C4E stuff right when it came out. Sadly I was disappointed because the jacked leaked where they had sewn in the C4E logos on the front and back. It was just embroidered an there was no sealing on the inside. Since we were in a drought last fall, I could only test in the shower and sure enough, those two spots soaked through. I also concur that the pants were quite long and I didn't want to attempt to have them hemmed or anything which would affect the waterproofing. So, I returned the set and figured I would let them work out the bugs since, again, it was brand new.
Now, I do have to say that I was relatively pleased with everything else about them but I don't have experience with much of the "higher end" gear like KUIU or Sitka. I saw the Kryptek stuff in my local Cabelas and I think I liked the makeup of the C4E stuff better. Again though, I really don't have any true field experience with any of them. I can't blame anyone for trying the C4E stuff since it is a much easier hit to the wallet when you catch it on camofire but just make sure to do some testing at home before you take it into the field.
