    Lock Knee

    Does anyone else have problems with knees being uncomfortable because the feet are supported and the butt is supported but the knees are not?

    I have a few ways to try to help fix this but was wondering how others deal with this problem.

    What I do is put a stuff sack with clothes under the knees, the more stuff in the sack the better. Sometimes I can move around to create a fold that lets the feet sag down a bit and supports the knees. But usually after a couple of hours, I have to get up and walk around a bit to ease the discomfort.

    Maybe I just need to stretch more?

    What hammock are you using? I had the same problem in my HH ULB - part f the reason I quit using it. I think it was a combination of the way the hammock is whipped at the ends and the fact that the ULB is probably a bit too short for me at 6'.

    I whip my homemade hammocks using Jeff's "W-whipping" and that makes a nice, high ridge through the center and nice, deep pockets at the foot - supports my knees fine.

    I use homemade hammocks, and have tried hems, folds, knots and whipping to secure the end. However I have always kept the ends even and not tried pulling out sections of cloth to shape the hammock.

    I will take a look at the W-whipping page, that sounds promising. Anybody have a direct link?

    I feel that in mine. I am able to put enough stuff under my knees so this is not a problem. You might want to try pitching your hammock tighter, looser, different whipping, or longer ridgeline. Basically just different from what you are doing. I found that for me, just changing something small made a big difference in the way I felt.
    Is that too much to ask? Girls with frikkin' lasers on their heads?

    It's funny this should come up as I was just about to post about knees. My left one has been acting up recently, it feels kind of like a mild hyper extension. I cant work out if its hammock caused, hammock exacerbated or just one of those things.

    I'll have a go at changing the sag, possibly even have a crack at a home-made as i'd hate for this to be a deal breaker.

    When I was in Panama, sleeping in a net hammock, this seemed to be a problem. The way I addressed the issue was to sleep at more of an angle. It seems that if you are already using an asym hammock it is probably caused by the hammock being to short. Or it could be the pitch of the hammock?

    Try more angle and sleeping on your side with your knees bent.

    By all means, don't let it be a deal breaker. When I finally followed the advice of others here and put a little clothing in a stuff sack under my knees, problem completely solved! I think it also helps between my knees when I'm on my side.

    I'm not quite 6'1". But I have the longer UL Explorer Asym and have always had the lock knee problem even when laying on the diagonal. Maybe I don't have enough sag? But, I thought the integral ridge line was to assure a constant sag? Next time I hang my Speer I'll have to pay special attention to the knee problem. I'm not certain, but I think the knee lock might not have been as noticeable in the Speer. Regardless, it is easily solved just by putting something under the knees.

    Make a longer and wider hammock, then hang it with a LOT of sag and lay way diagonal (yes, way diagonal is the technical term). After some experimenting, you'll zero in on the right length/width/sag combo for you.
