These deluxe lightweight padded cases are specially designed to integrate with our products. They are hooked on to our packs with the Padlock system, or can be slung onto a sternum strap. These are not ordinary accessory pouches. As you would expect from Eberlestock, these are high-quality, finely built cases designed to protect valuable equipment. The A2SP (shown in photos with Nikon LX Premier 10 x 42 'nocs, not included of course) is a binocular-sized case, with a second pocket for small sundries. The main compartment is lined with our extra-soft, fleece-like material.
