Field tested for 3 full seasons before being introduced in 2006, our Natural Gear silhouette bag is made of 600 Denier material with PVC backing material.  Due to our extensive field testing, high stress areas have been identified and reinforced with extra stitching.  Unlike other silhouette bags currently on the market with complicated straps, folds, and buckles, our bag uses the minimum number of straps and loads/unloads easily from the top.   The bag easily hold 4 dozen decoys.
