Does anybody know a source for the inflatable lumbar bladder (with hose & pump bulb) that goes in some parachute packs - like the old Security 150s?

Go to Amazon.com (or better yet to smile.amazon.com where your purchases support the SSA!) and search for 'Inflatable lumbar support travel pillow'. Plenty of examples of inflatable cushions with a rubber bulb attached in different shapes available.
