I'm cleaning out the shed and have two Black Diamond Squall tents for sale. Both have been used on one expedition in the Alaska Range, but are in great/perfect shape.
These are 3-person / 4-season tents that are very light compared to most of their size and strength, weighing in at about 8.5 lbs or so. The pole configuration is ingenious, but not totally intuitive, so watching the how to set it up video on the BD site is recommended. Once you understand the sequence, these set up really fast and easily. They have spacious vestibules, good ventilation, when you need it and bomber protection. They retail for about $600 I'd like $275 +shipping for each.
I also have a Sierra Designs Origami 3 pyramid-style tent for sale. This is essentially a version of the classic Megamid, but is bigger and has five sides, rather than 4, like a classic pyramid. It has a clip-in, washtub floor and was used for one night, so it's in mint condition. These make great kitchen tents for expeditions or light weight shelter for desert trips, etc. In a good snowpack (or on a glacier), if you dig the snow out below it and you can fit 8+ people in it, carve benches, cook table, etc. This retails for over $250 with the floor. Looking for $110 +shipping.
I can email pics of all aspects of the tents if you'd like. Either PM me or email at ophirtodd at gmail.com
