Free Shipping. Eagles Nest ProNest Hammock The ProNest Hammock by Eagles Nest is the smallest and lightest hammock yet from ENO. The latest hammock from ENO is five ounces lighter than our SingleNest and even more compact but still offers the same ease and comfort that has created a following around the world. To reduce weight, we redesigned the attachment point, using custom aluminum carabiners and created for the hammock that is smaller, yet just as comfortable as any of our other hammocks. The ProNest's size and weight allows users to pack more and go further wherever their adventures bring them.
