HexLite – Making a spacious, full featured, sub 2 lb. tarp tent.

YouTube videos for tarp tents often show a 3 meter x 3 meter tarp being pitched a number of different ways.  One makes a single pole, hexagonal tent with a large interior and overhanging entry,  It is described as a great emergency shelter, roomy and quickly pitched.  I wondered if it could be made as a stand-alone lightweight backpacking tent.

I experimented with a cheap 10′ x 10′ blue plastic tarp to  visualize the design and interior space.  Using some of the new, reasonably priced, lightweight coated polyester fabrics now on the market, how light could it be?  Well, it’s finished and what’s not to like about a final overall weight of just 1 lb. 14 oz., including a 42 sq.ft. floor, 49″ center pole, stakes, bug netting door, and stuff sack.

I started with 7 yds. of silicone impregnated, 0.93 oz./sq.yd., Membrane Silpoly fabric from Ripstop by the RollContinue reading

A DIY, ultralight, multipurpose bivy sack

In the past, on some multi-day climbs, I slept under a tarp, with my quilt and air mattress inside a bivy sack.  I also had other nights in a tent, in alpine country, with condensation  wetting out my exposed quilt.  Sometimes in shoulder seasons, my quilt isn’t quite warm enough.  Then this year I discovered a great source of ultralight fabric.  These were all motivations to try another project – an ultralight bivy, with options for bug protection and a cold weather liner.  I finished it and have now tried it out successfully on a cold night.

The fabric source is Ripstop by the Roll.  They offer a wide assortment of coated and uncoated nylon and polyester at weights as low as 0.56 oz. per square yard.  Continue reading

Tarp tenting

“Almost tarp” tent

Tarp shelters are a common solution to ultralight camping.  They are simple, light and easy to build.  But they only provide a roof.  Walls (bug protection) and floor are extra or missing. “Almost tarp” tents address this.  My Six Moons design Night Wing tent is a good example.

The Night Wing is basically a tarp with netting closing the ends and edge.  It couples with a custom Tyvek 1443R floor.  But on a recent alpine climb approach, I was bothered by a lot of condensation that was wetting out my sleeping quilt.  Adding a bivy bag over the quilt or bag would give me both warmth and separation from condensation.  But that’s another pound!.

Alpine tarp bivy

The next outing involved two nights at a high camp at 7500′.  I decided to go lighter taking only an old sil-nylon tarp I made a few years ago and my very old Early Winters Gore-Tex bivy bag, to which I had recently added a waterproof zipper.  It worked, but the tarp had been designed only as a cooking shelter and was really not long enough to fully cover the bivy bag.  In practice this should not be an issue to have a waterproof bag sticking out into the rain, but….  In thinking about it, I wondered if I could easily improve things. A few hours of sewing and an ounce of fabric later, problem solved.

A 2.8 oz. backpacking chair

Out in the wild I really miss a comfortable place to sit.  So here is my accessory that makes a Big Agnes or other air mattress into a chair.  Complete with a small storage pouch, it weighs 2.8 oz. Some sil-nylon fabric, 3/4″ webbing and two side release buckles, coupled with sewing machine time and presto. Slide the top and bottom sleeves over the ends of the partially inflated mattress.  Fasten the webbing straps together, adjust their length and the inflation level and you have wilderness comfort.

I have used commercial versions in the past that used stays to keep the back rigid.  They were a lot heavier and did not pack down well.  This approach solves the problem by Continue reading

Black Diamond Mega Light Project – Part 2

BD MegaLite finishedSome projects take longer to finish than others.  But here it is, the Black Diamond MegaLight modified for 4 season use.  It now has bug netting, as well as optional bath tub floor and rain awning. While no longer in an ultralight category for 1 or 2 people, it is pretty light for 56 sq.ft. of floor space with a 65″ center height.  It sheds rain well and can be secured against high winds. I can pick and choose elements to include, depending on the trip, and pack a shelter system weighing between and 2 and 4 lbs.  Part 1 of this project covers the tent as set up for winter snow camping. This post describes making it suitable for rainy, summer outings with bugs. Continue reading

Black Diamond Mega Light Project – Part 1

BD ML MORA

Late fall in the Pacific Northwest brings rain and darkness.  It is a good time for projects.  This one modifies a Black Diamond Mega Light sil-nylon pyramid tent to add tie downs, wind guys, insect netting and wet weather features, while still preserving it’s usefulness for winter snow camping.  And of course, doing so with minimal added weight.

So here is the Mega Light, practice pitched on a nice spring day in Mt. Rainier National Park.  The basic tent weighs only 25 oz. and can be pitched hanging from an overhead line or with a center pole.  You can use a pair of ski or trekking poles with a supplied coupling accessory, or the 11.4 oz. carbon fiber sectional pole that comes with the tent.  Tent weight of 2 lbs. 5 oz. for over 50 sq. ft. of interior space and 65 inches of head room is pretty light.

Still some customization can produce  an even more versatile, big four season  tent, in the range of comfort light packing. Continue reading

End of season review

New snow - RainierMt. Rainier is now wearing a new coat of snow and the high country is making the transition to winter.  Days are short, the rain is arriving and it is time to look ahead to ski season.  This is  a good time to reflect on this year’s outings.  What worked well?  What didn’t?

Comfort light delivered for me this season.  Good, light weight equipment continues to open opportunities.  My wife and I are backpacking again, without me as the mule.  I am able to do grab and go trips to support climbs requiring a base camp.  Bake a load of Logan bread.  Take a quick shopping trip and I am off.  With less gear, packing is quicker.  In the past even overnight trips seemed to have packing drama.
