Tamrac makes superior bags and carrying systems for cameras. These American-made bags are designed to be extremely durable. Tamrac products are intended primarily for outdoor photographers who need the utmost protection for their delicate equipment in sometimes harsh conditions. These may include mountain-climbing photo shoots or wherever there's a lot of rain.
The water-resistant backpacks, tote bags and other types of cases are an ideal way to organize one's gear, especially if there's a lot of it.
Nearly indestructible fabrics such as Dupont PowerGrid, PolyTek and Kevlar-based materials provide the exteriors, while numerous interior compartments in the bigger models are made of soft but ultra-sturdy foam padding.
