Rapid, convenient camp set up and take down. Foam pad eliminates cold backside. Rain fly offers protection from snow and wind. Excellent for backcountry ski touring. The Mayan hammock is designed so that a person lies in a diagonal or crosswise position rather than lengthwise.
Most hammocks are all about the same length, approximately twelve or thirteen feet long.
The difference in size is in regard to how wide the hammock will spread. Sizes 16 and 20 are best for overnight sleeping.
