Climbing into or out of a hammock is a full round action. A successful DC 5 Dexterity check reduces this to a move action.

A hammock is a piece of stout netting, some nine feet long and four feet wide, with a long rope at two ends. By tying each of the ropes to a tree branch (or something similar), the hammock can be suspended in the air. A person can then climb inside the netting and sleep securely and soundly, elevated from the ground and out of the path of any creatures that may come wandering by.
The hammock requires a successful Rope Use Skill check (DC 10) to fasten securely. Once this is done, however, there is no chance an individual sleeping in the hammock will fall out in his sleep. The hammock can safely hold up to 400 pounds without breaking. When not in use, a hammock can be rolled up to half the size of a bedroll. The hammock is a good means of concealing oneself from potential enemies while one sleeps, so long as the potential enemy is travelling on foot. Noticing a hammock slung in the trees requires a Spot Skill check (DC 20), if the creature making the Spot check is not specifically looking up into the trees. The DC of this skill check may be raised or lowered at the Games Masters discretion, depending upon such variables as any further attempts to hide the hammock or exceptional eyesight on the part of the creature making the Spot check.
