Welcome to BPL!!
Thanks a bunch for sending me out some of the small packets.
As somebody who has already posted in this thread a few times I thought I would give you all an update on my very limited use of this "Gurney Goo".
I acquired some of the sachets from Phillip and have used it the last three days while out in some wet conditions - and initially around the house to make sure it did not have any adverse effects on my body.
Each sachets, as Phillip stated above, could easily be last two days if all you are doing is using it on your feet. Kind of a bummer that each sachets holds so much. They end up being more of a mess than anything. Think I will just stick with a bigger container that I repack into a 1oz container with a lid. If you do a whole body application (feet, hands, inner thighs, nippes, monkey butt, etc) than I can see a single sachet being used all the way.
How it compares:
So far I would say that it is pretty much identical to Hydropel in regards to wet feet prevention. By far better than bodyglide and that Bonnie's Balms stuff based on some very preliminary use. I went through a half-dozen to a dozen creeks and when I got back to my truck each time after the hike and took off my wet shoes and socks, my feet pretty much seemed the same as they would if I was using Hydropel.
Sadly the little sachets I got did not have any ingredients on them... so I still have no idea what in the heck is in them and how they chemically compare to Hydropel. Neither their official website or the one that Phillip has, nor any other website I can find, lists their ingredients. Kind of worries me - I would like to know what I am putting onto my feet - a rather important part of my body as a hiker.
Anyway, at this point I am going to keep using it to see how it will perform. The real test will come in a few months when the rain really starts to hit the Redwoods and every little creek here becomes a wanna-be river.
