Question: Are these the right size for the Hennessy Hammock Hennessy Expedition Asym Class M10?
Document: These keep the the hammock clean and neat. They sent the bigger size that slide over very easily. You have to have these.
Snakeskins (plural, there are two of them) really make set up an tear down a snap, like one minute. Hennessy direct includes them with their hammock tents, but if you bought it elsewhere, as I did, you owe it to yourself to get a pair.
These are a brilliant way to quickly strike camp when using either a Hennessy hammock or Eno hammock. There is no stretch to these so the bulkier Deluxe Hennessy hammock was a very tight squeeze but it still works. Completely weightless upgrade too.
The snake skins are perfect for packing up both the Hennessy Hammock and rain fly altogether. All you have to do to unpack is hang up the hammock and push back the snake skins..... then viola....  you are unpacked and ready to sleep. Hardly any work involved. Would definately buy again.
If you have a Hennessy hammock or other bundled hammocks this is an indispensable piece of gear. It cuts setup and take down time in half. Which is a pretty amazing feat since setup is already simple. I am able to roll up the hammock, rainfly, and even stash the tent stakes inside of the snakeskin.
I use the snakeskins with my hammock and my tarp. Using the snakeskins keeps the tarp and the hammock off the ground and clean, makes packing easier and prevents entanglements with shockcords etc.. I can hang the tarp and hammock and leave the snakeskin sleeves attached until I am ready to deploy the tarp and or hammock. A must have accessory. Nither my hammock or tarp is made by Hennessy, but they fit well.
Love my hammock. Very comfortable and unbelievably easy to set up anywhere. Setup and breakdown is quicker than any tent I could imagine. Saves a ton of pack space for long or strenuous hikes. The hammock proved to be over 5lbs of weight reduction right off the bat, but should be noted that it's design allows for the volume in pack to be far reduced from any tent with poles.
I bought a pair of these for my Hennessy hammock. I tried them, but I think I prefer using a stuff sack. Using the snakeskin takes up more space than a stuff sack. But if you attach it to the outside of your pack, that probably does not matter. I did not like the way the snake skins bunch up at the ends of the hammock. It makes using the hammock in tight spots a little harder. I tried to put both the tarp and hammock into the snake skins.
these really work. A must have for your hammock.They fit good.
Gotta have if you own the hammock makes it easy to set up in fair or bad weather awesome invention
