I've got quite a bit of Krptek pieces. I've got the Koldo raingear, I like it alot, but I've rarely had to really put it to the test, as we just dont get day after day of constant rain in CO, WY, MT, or NE where I hunt most. I have a pair of Valhalla pants, that I actually really like but the button has come off, and the stitching is unravelling in spots. They made it through 3 seasons of pretty hard hunting though. The fabric also piles pretty bad where you go through briars and stickers. I also have the Alios pants and I do not like them nearly as well as the Valhalla, but they are thicker material. The pieces I like the best are actually the Vellus set. I use it for tree stand hunting whitetails, and wear it out on late season tags or rabbit hunts.
Overall, its decent quality gear, and if you get in on clearance prices, a good value. I dont have any experience with the Altitude line however, so I would hope at those prices, that quality and construction would reflect it. The pieces
