It says a lot when a guide chooses a tent on Everest. This shelter must be exceptionally strong, after all this space will be your sanctuary when you need it most. If a hurricane is blowing in the bay of bengal and the temperature in Camp 2 @ 21,500ft drops to -20f with gale force winds, the tent you have chosen is not just a structure… It’s life support.
And this is just what happened at Camp 2 on May 6. A big wind storm kicked up at night and blew fierce in to the morning, reports speak of 50-80 mph winds that devastated 30% of the entire camp. The Mountain Trip team only lost two tents in the ordeal and everybody is doing just fine.
“Just wanted to let you know that the LFD is hanging tough up at Camp 2 (21,500 ft +/-) in 50-80mph winds while other tents are snapping poles. Scott Woolums is up there today, and said the dome is doing great. I just came down to base camp yesterday with my crew, after spending the last week up there and really think that the LFD is the best dining tent or dome up at Camp 2. We really appreciate all the windows, and ventilation options, the big doors, etc. The biggest concern that we had was how it would do in the wind, and it is standing up to the test right now. We were able to secure it really well all the way around. Climbers from other teams stop by regularly to check out the dome and I think they are all jealous.”

This is where the little details become HUGE factors.
SlingFin is the first to use ET70 (titanium dioxide bias binding) on the tent body and perimeter (BFD and LFD). This is an important detail since nylon and polyester bias bindings will degrade much sooner than the rest of the tent which is made of ET70.
All perimeter tie-outs and grommet tabs have a grosgrain reinforcement. This helps to strengthen the tent fabric in high stress areas where the fabric is under excessive tension or areas with bar tacks.
SlingFin tents are equipped with Easton® Expedition grade 7075-T9 tent tube. Easton aluminum tent tube is hard anodized and has the highest yield strength available in the industry.
All stress points are reinforced with extra fabric or grosgrain and sewn with a bar tack or reinforced by back tacking the stress area. Back tacks are most commonly applied to stress areas that would be damaged by a bar tack machine.
These are some of the little details and fine points that separate a thoughtfully designed mountaineering dome from a pile of poles and fabric.
