The SKB Dry-Tek Handgun / Pistol Bags feature the patented "Dry-Tek Difference". The two-layer padding will work in tandem to draw moisture from the inner bag. The inner pad layer enables water to pass through to the outer layer where a remarkable one-way laminate membrane applied to the outer layer allows water molecules to exit the bag, but not to enter. The result, your gun stays dry! In addition all Dry-Tek handgun / pistol bags feature oversized nylon zippers, slide-through system for padlock security, and exterior pockets for clips and accessories. All hardware is cast and rust repellent.
