Hammocks

For me, an any weather, all year round ,sleeping sensation.

Key benefits;

-Quick and easy to set up
-Small and compact pack size relative to the amount of shelter you get
-Plenty of working room and the hammock doubles as a seat
-Low impact on surroundings, you'd never know you'd been there
-Exceedingly comfy and cosy

DD Hammocks have a pretty darn good range of hammocks and tarps, at pretty darn good prices. 

Also my DD hammock has two layers which zip up, so on windy nights you can cocoon your self into a bundle of warmth. Genius.
