What is the purpose of double sleeves on OREX coveralls?
The double sleeve is designed to prevent use of tape or another closure device at the top of the glove. The inner sleeve is rolled down, the glove is put on over the inner sleeve and the outer sleeve is rolled down on top of the glove cuff. This double sleeve design is very popular at many nuclear stations. The inner sleeve also has a thumb hole to aid in preventing the sleeve from sliding up the arm.
