I'm selling my altitude tent on ebay and I thought that I'd put the link up on here too.
I've had it for a couple of years now but my competitive running days are over and I no longer have a use for it. It's a complete system with the tent that fits around a queen-sized bed and a Hypoxico Summit Generator which takes you up to 12,500 feet. It's in perfect condition and I have all the original boxes and everything that it came with when I purchased it.
I'd like to get $3,000 for it but if you're interested email me and we can discuss prices / I can send you some pictures.
