In inclement weather the number one priority is staying warm and dry. These new 2-layer waterproof, windproof, breathable jackets are better than ever. The secret to our new jackets are the high quality, environmentally safe Bemis seam tapes. Seam tape is the critical link in the chain of waterproof protection and Bemis is the recognized worldwide technology leader in providing thermoplastic films for a myriad of industrial applications. The H2O Proof 3-in-1 Jacket can be worn as an unlined extended length jacket, as a warm, lined parka with the zip-in jacket, or the Inner Cumulus Jacket can be worn separately.
