Daba Doo, the company that makes this terrific carrier actually calls it a "
Companion Pack," and that's a great description! This is a wonderfully soft, padded pouch, with mesh side panels for ventilation, a cinch closure for security, and a leash clasp for total control. For you; wide, adjustable shoulder and waist straps buckle securely with a single parachute-type clasp in back. A bib-type top to the pouch keeps fur off your clothes!
