When spending time in the outdoors, there is always the threat of weather. To combat foul weather outdoors, participants should understand the importance of proper dress. The basic rule of thumb is the layering system. This system uses three layers.

1. The first layer should include a lightweight synthetic layer; it's job is to remove moisture from the body. By removing moisture from the skin, the body is able to maintain a safe core body temperature and avoid hypothermia.
2. The second layer is an insulation layer. Ideally, the second layer will relate to the amount of activity and the outdoor temperature. If the weather outside is extremely cold then a heavier fleece or liner should be used. *Avoid the use of cotton clothing. Cotton has poor heat retention qualities and when wet it loses all insulating properties and is very hard to dry.
3. The third is the shell. The shell is important because it acts as the first line of defense against the outside environment and should be weather resistant. When choosing a shell, technologically enhanced fabrics are excellent options such as Gore-Tex.

With a proper layering system, they can be adjusted as the hike or day progresses. If the individual becomes cold, a layer can be added. If the individual becomes too warm, it is easy to remove a layer.

Proper dress in the outdoors should also be a concern for individuals with disabilities. For example, individuals in wheelchairs often have poor circulation in their legs due to a lack of motion and from a prolonged amount of time in a sitting position. Individuals who use wheelchairs also often have limited or no sensation in the lower legs. This can be a concern when choosing the proper clothing.

One may need to use extra clothing at or around the legs and should closely monitor his/her body. Ways to monitor the body include looking for:

• Visible signs of distress or discomfort;
• Discoloration of skin, both exposed as well as under clothing; and
• Skin that is excessively cool or hot to touch.

For individuals with limited motor control, garments that are easy to dress and undress are also good choices. Some important clothing features to look for are large zippers, Velcro straps, large buttons, snaps, and large sleeve cuffs with draw strings. Good communication between the backpacker with the disability and his/her backpacking partner (if present) will ease some concerns about how the individual is feeling.
