IMO, shelter and related items are
not in the "not much to lose if things go wrong" category. Not getting a good night's sleep quickly takes all the fun out of riding. Depending on where you tour and how spectacularly your gear fails, it may take days to get things fixed again. If you're on a globe tour for a couple of years, couple of days is probably just an inconvenience, lessons learned etc. On a two week tour it can be a major hassle.
They say good judgment comes with experience, and experience comes from poor judgment. If you do choose to buy this pad, please report back so w'all have at least anecdotal, second hand information on how things worked out.
