I’ve never overnighted in a hammock, but some of my hiking friends swear by them. Once you try it, they say you will become a convert. Most often used in fair weather, hammocks are becoming more popular. Hikers using them bring up some good points:
1) You sleep or rest off the ground, which may be soaked, damp, and cold.
2) You are away from creepers and crawlies.
3) Animals will get into tents, not hammocks.
4) A more comfortable and better way to sleep I emphasize this last point because it’s what I hear most often from hammock lovers. They claim it is a better way to experience deep sleep on any hike.
What about if it rains? Got ya covered. Take a look at this hammock, which sports a tarp and mosquito netting. I like the idea of keeping gnats and mosquitos out, but letting air in, all under a protective rain-fly. Here’s another model designed for tall people. Seems like you will find a hammock for even the fussy among us.
This website, Hammock Forums, surprised me. It is the first and last word on hammocks. One article details how hammocks are used in winter conditions! I won’t be testing one anytime soon, but I’d be interested in hearing from anyone who uses a hammock regularly on an extended hike.
