Earthly Camouflage (3.5e Equipment)
From D&D Wiki
This kit consists of loose-fitting garments and jars of impermanent paint. Its items are colored in various shades of beige, brown and gray. The clothing can be worn over armor and the paint applied to any portion of the body. When in a desert, mountainous or similar terrain, characters using this kit gain a +2 circumstance bonus on Hide checks. Circumstances, such as snow, may change a terrain's usual appearance, rendering this kit useless. Camouflage kits are exhausted after ten uses. Each use lasts until the garments are removed and the paint is washed away.
