Abstract
A sack for enclosing and compressing resilient materials, such as clothing items and sleeping bags having high air content filling, i.e., down filled matter or synthetics incorporating air voids, in the form of a stuff sack having a plurality of longitudinally extending adjustable length straps attached to the sack at opposed ends thereof and equidistantly spaced around the circumference of the sack, such that when the sack is "stuffed" in a conventional manner, substantial additional longitudinal force may be applied either by the straps or externally, and the straps shorten to telescope the sack into a compressed and stable configuration.
