If you don???t have immediate access to a hospital, wrap the person in blankets, coats or other materials to gently restore heat to the body and avoid jostling the person, Parrott says. ??? Jeans aren???t the best material to wear in the wet snow because they absorb moisture, but if you layer them with long johns and don???t get too wet, you???ll be OK. Just make sure they???re loose-fitting jeans
