Ghillie Suit (3.5e Equipment)
From D&D Wiki
A ghillie suit is a camouflaged outfit that resembles heavy foliage.
Gathering foliage for the suit takes about 3 minutes, and a DC 10 Survival check. After that a further 5 minutes must be taken to attach it to the suit.
When set up this way, the suit will add a +3 to hide checks when lying in light foliage, or +5 in heavy foliage. In this way, one can also attempt to hide in plain sight.
Cost: 3gp for the suit to be attached to.
Weight: 10 pounds.
