Tents for Alpine climbing base camps: What are you all using?

Forrest McCarthy wrote:When exploring the Winds and Sawtooths I use the HMG UltaMid (www.hyperlitemountaingear.com/ultamid-4-person.html). In addition to being ultra-light (just 1.3 pounds!) the 4-person sports a spacious 85 square feet of floor space – plenty of room for spreading out gear. If set up properly, the HMG UltaMid is dryer than a double wall tent as it ventilates better and any moisture drains out. When camped below timberline I often hang the apex off a line tied between two trees so there is no center pole and even more room…. very luxurious. Early season in the Winds is buggy and the mesh insert (1-pound) will keep the mosquitoes out. In addition to both winter and summer adventures in the Rockies, I have used my HMG UltaMid on expeditions to Mongolia, Patagonia, and Alaska. After three years of heavy 4-season use it is still going strong. Look for it in the Winds this summer.
