PROBLEM STATEMENT
There is a need for a better sleeping bag for people with spinal cord injury, limited hand grip, and wheelchair use. It should enable those with disabilities greater enjoyment and independence in the outdoors, by making camping a less stressful and more rehabilitating experience

RESEARCH
observation @ U of U Rehab
rock climbing exploration
hand cycling at Liberty Park
talking to experts
online forum research
Our patients do independent activities all day while camping, but then require assistance to go to bed getting outside fosters
-Dr. Rosenbluth
most people adapt current products to meet their needs
independence and healing
adaptive tools are expensive and
equipment can create a disconnect
not necessarily well designed
with the outdoor experience

My business model for this sleeping bag would be the first one we talked about. I would send this tech pack with a sample to a manufacturer, then iterate back and forth until it is exactly how I want it. I would then sign up for the Outdoor Retailer tradeshow and create a killer booth to showcase my product. I would reach out to buyers beforehand who I feel would be interested. This would be the big ones like North Face and Patagonia, as well as smaller lifestyle brands like Poler and Nemo. I would hope to get orders and follow through with those. I also think this design would do well through crowdsourced funding on kickstarter. To do that I would make a prototype myself as close to what I want as possible, then make a great movie and online presentation for it. I would then hope to get funding that will get me through the rest of the iteration with manufacturer’s so I would then be able to deliver my product as promised. This wouldhelp my product get known and possibly be ordered by outdoor companies or I could continue to manufacture and sell them myself through and online store. 21
