OneUp on Rainier





The OneUp on a bluebird day. Mt. Rainier.

While the SlingFin crew was going through the paces on the “river of no return“…

The OneUp was getting put through the paces on Mt. Rainier.

One of the main goals of SlingFin is to produce the best gear possible with inferred design principals from real users, guides, and outdoor professionals.

The best way to do this is simple. Get the gear to the mountain and into a guides pack… Then tell them to beat it up.

The guides using the tents had some great responses to the design of the tent, and some even better ideas and feedback!

Yet another photo of a big mountain where all the tents in view were designed by Martin Zemitis.

SlingFin is making headlines!

No, its not because of the reports of U.F.O sightings on Gilman St..

It’s about L.F.D sightings on Everest!

“When a team of climbers reached the summit of Mount Everest on Thursday, they had a significant advantage over other teams this spring, many of whom were forced to turn back short of the world’s tallest peak by bad weather.”…..


……”Our goal is not to build this business up and sell it off. We’re not a marketing company; we’re a product-driven company that in the long run will translate into relationships with the people who appreciate this gear and will support it. In the short run it will be very challenging, but this is the way to properly brand the business in the long run.” Read the entire article here.



Alpine Ascents’ website officially reports: At 4:22 am on May 20th 2011, Garrett Madison, Tom Halliday and Kami Rita Sherpa made the summit of Lhotse!

This is a truly amazing feat of mountaineering in all aspects of the sport. The level of skill and sheer endurance that this type of climb requires is possessed by very few people on this earth.

The Guides’ Choice.

Inside the L.F.D during the windstorm. Human reinforcement!

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.”
-Bill Allen Mountain Trip.

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.


First Image of the One Up on Everest!

Today is a big day for us. The first images of the OneUp nestled in on Everest at 19,800 ft  have come in courtesy of Garrett Madison. The wind has been howling up there pushing gusts of +60 knots over night. Garett and two other guides spent the night in the OneUp with the inner body set up for warmth and extra protection. Reports were that the vent system works great in high winds, allowing for minute changes in the zipper apex in order to control spindrift and airflow. The crew at AAI have been putting the SlingFin systems to the test in some of  the harshest conditions anywhere on earth. We gave Garett a custom Easton Carbon Fiber pole set for this expedition, shaving almost a pound off the total weight of the tent.

We are very happy to provide this level of high-end gear supply to guide services on Everest. We see it as a mutuality beneficial relationship. They get a supply of what may be the finest expedition shelters ever made, and in return they get to beat the living bejezzus out of it, and come back with advice and design ideas that are impossible to test under average conditions.



The L.F.D is at Camp 2!

Located at 23,000 ft Camp 2 is also known as advanced basecamp, because it serves many of the same duties as the lower camp just smaller. This is exactly why we built the 200 square foot L.F.D.  With ten easton poles and ET70 fabric coated with titanium dioxide, the L.F.D is right at home here, and can withstand these harsh conditions for a very long time.

Reports are that Camp 2 has been getting pummeled with 50-60 mph winds over the past few days,  yet the L.F.D stands strong providing shelter for the group to eat in.

Many thanks to our friends at Mountain Trip for all the great photos and in-depth blog postings!

If you want it done right, do it by hand.

Things have been very busy over here, between shipping tents to Nepal and working on new designs I have had  little time to blog about whats going on.  One of the things I’m really stoked on is the signage on the new space.  Jonathan Buck and I hand painted them and they look great! We even had some folks from the motorcycle shop across the street come by and ask if they could hire the guys that did it!

Getting ready to get dirty.

With a six pack and a handshake we sequestered the use of a scissor lift from the construction crew renovating the buildings around us. Armed with buckets of primer, rollers, tape measure, plumb line and Jonathan’s sweet Carhartt onesie (I was a little envious) we set out to work on what we thought woud be an easy scissor lift ride.

We were sorely mistaken. This beast had “Genie” emblazoned on the side panel. Now I don’t know if there was a genie in this thing, but it was definitely possessed . The joy stick had a twisted sense of humor, you wanted left it would go right, sometimes.. Other times it wouldn’t do anything, every now and then it would go left if you were lucky. However if luck was not on your side, it would leave you stranded 15 ft in the air.  Like all machines it started to show trends in behavior, and with just a bit of percussive therapy and patience we had it working for us.  Honestly, figuring that crazy thing out was the most fun we had all day.

The Gilman street-side sign

We painted three signs in two days. I was really following Jonathan’s lead on this one, he’s the artist of the gang. In fact he is one of the most photo realistic artists I have ever seen. We made a good team, he detailed while I filled in the blanks.

The rear sign. Finished with sunshine to spare.


The other thing i’m excited about is the effect we are having on the community. I found a Google street view of the warehouse before it was renovated. It is quite amazing to see the changes that have happened over the last few months. When we first moved to our basecamp, across the street was filled with trash, sofas, chairs, clothes and guitar cases there was even a giant stuffed monkey with over sized clown sunglasses.That trash had to go, or at least get decorated. Lucky  for us we just had a set of SlinFin stencils made and were eager to try them out, so Tim and I went across the street and did a little test.. We recuited one of Berkeley’s famous street personas to help us clean up the mess. He turned out to be a very lucid an intelligent fellow, and he had a killer work ethic!  We tried to help him but he refused saying, “I am fiercely independent!”  We loved this line and adopted it as a bit of a mantra.

We asked him how much he wanted for the job, stating that we had offered the previous guy (who never showed up)$40 bucks.  He said, “FORTY DOLLARS! I’ll do it for twenty and a banana, and ill do it right now!”  I bought him some juice and fruit and he went to work, meticulously moving the debris into the large dumpster we acquired. He had it cleaned up in no time flat, he even raked and swept the area.  We gave him forty dollars. He totally deserved it.

Future. Classic.@ SlingFin HQ

The L.F.D from outside our front door


The area is really starting to look a lot better. There is new life being poured into this once forgotten industrial lot in east Berkeley. And people are taking notice, we get dozens of smiles and waves through our front door every day.

That’s all for now, I have to go get some paint out of my shorts.

BIG THANKS to the Mountain Trip team! These folks are putting SlingFins gear to the test and coming back with fantastic beta, and some amazing photography as well.

The B.F.D @ 17,500 ft Photo- Chris Davenport

There is something very satisfying about seeing the B.F.D. in its rightful place. To see a design go from paper and rulers to an extremely refined structure sitting at 17,500 ft set up as a communication center, or the L.F.D in Camp 2 as a dining tent (21,500 ft) it’s very cool.

From M.T’S Blog: ” Camp 2 is sometimes referred to as “Advanced Base Camp” (ABC) and we supply it to create an essentially smaller version of our base facilities. We have a kitchen tent with 4 Sherpas working hard to keep us fed and camp running smoothly, and a smaller version of our massive SlingFin dome that we’ve set up for our dining tent. The rest of the Sherpa team keep delivering loads of food, fuel, tents, and oxygen up here every couple of days to stage for the upper mountain. This morning they showed up with a dog following them. The dog crossed all the ladders with ease apparently… We’ll try to track down a photo of the dog on the ladder and post it later.” I will definitely stay tuned to see a shot of that dog on an ice ladder!

Chris Davenport is one of the members of the Mountain Trip team. He just wrote a new book; Fifty Classic Ski Descents of North America. And from the looks of the above photo this guy is truly hooked on skiing. He is also the one taking some of the sweet night shots.

Puja footage!

The crew here at SlingFin would like to thank all the wonderful people who were with us at the puja on April 2! If your thoughts were the only were the only thing that could be with us, please enjoy this footage shot and edited by the preeminently talented Viva Barrows. (You can see more of Viva’s work here.)

Puja Ceremony – Blessing by Lama Tenzing from Slingfin on

If you didn’t believe what I said about Tsering’s voice in the previous post, here is the  proof.

Mountain Trip just had a puja of their own. While the price for uploading videos from Everest is astronomically high, these clips will give you a general idea of how a puja is held. For more Everest puja shots go here.
