Spider Holsters allow you to carry your SLR somewhere other than your neck. Now they’ve expanded their line into a new dual camera system, so you can strap two cameras around yourself. The DualCam system will cost $235 for a complete kit to attach two SLRs.
Great for those who prefer to carry a few cameras instead of multiple lenses. If you’re only carrying one camera, you can remove one of the pads, and travel a bit lighter. Spider also sells a conversion kit, for those who already have the single-camera edition. For $120, you get what you need to add a second pad to your existing holster.
