Bearikade rocks. Amazing product. Comes in three separate sizes, or custom. Is expensive and is the lightest when you compare volume to weight -- in this case, the Scout is the smallest NON-CUSTOM size, and it is 2.4 ounces heavier but has almost twice the volume (180 percent) of the Bear Boxer. It is worth it if you do this stuff alot. Though it is expensive, and 1.6 inches wider in diameter, so if you want to save money and/or need a narrower product, I can see why you might go with the Bear Boxer.
