What is the substrate used in the Crosstech Black 2F Nomex moisture barrier?

• A. Woven pajama substrate
• B. Nonwoven polyester
• C. Knit cotton
• D. Woven twill

Answer: (A)

Substrate choice affects how the moisture barrier performs and how comfortable the garment feels. For the Crosstech Black 2F Nomex moisture barrier, a woven pajama substrate is used because it offers a soft, smooth hand and good drape, which makes it comfortable against the skin under protective gear while remaining stable when laminated to the Nomex shell. This type of woven base provides a consistent surface for bonding the moisture barrier film, helping prevent wrinkling or delamination during movement and heat exposure. It also maintains dimensional stability under the heat and moisture conditions firefighters experience, which supports reliable barrier performance. Other fabrics—nonwoven polyester, knit cotton, or woven twill—tend to either feel less comfortable, drape differently, or add bulk and stiffness, which can affect mobility and laminate integrity. So the woven pajama substrate is chosen to balance wearer comfort with dependable lamination and barrier function.
