I have an old, 17 years, Sprayway Coyote 204 Gortex Jacket. Although its 17 years old it hasnt been worn for at least 12 years! Prior to wearing I have washed and re-applied the DWR, using nikwax, both wash in and spray on. Tumbled dried and cool ironed. Went out in it today and it was raining for a couple of hours, with strongish wind. At the end of my walk took the jacket off and there was obvious evidence of water inside the jacket - shoulders, hood, arms. No pack on, liteweight down jacket underneath. My question is the jacket past redemption? Do laminated fabrics beakdown over time? Im not able to check the seam tapes as the jacket has a liner
