***CHANGELOG FOR 2022***
We have added grosgrain ribbon under the corner reinforcement patches and bar-tacked all tie-out locations to enhance durability and tarp longevity for customers in very cold or extremely hot climates.  This adds 5 grams to the total weight.  See last picture for details. 

At 7.61 ounces WITH rigging, this is the lightest tarp we can make.  Palatial for one person with gear, this tarp can easily fit two as well, with 59 square feet of typical pitch coverage.

Catenary curves along the ridge and each side allow for a perfectly taut pitch and alleviate wrinkles, sagging, wind noise and water pooling.

This tarp is designed to be pitched using 2 adjustable trekking poles, although other types of pitches are possible without poles. The ridge guylines are long enough to wrap around medium-sized trees.

This is the lightest Dyneema variant that is able to be printed, utilizing one side of printable film.

This is a no-sew tarp (except for tie-out bar-tacks); the entire perimeter and ridgeline is bonded. A properly bonded section of Dyneema is stronger than the material itself.  Thousands of tiny punctures caused by a sewing needle can weaken the tarp under load, so we chose to bond the ridge and perimeter.

It is constructed from a Dyneema Composite Fabric variant that is 0.67 oz/sqyd, half the weight of the material used in our stuff sacks and rain mitts(1.43 oz/sqyd).

While this material is extremely tough in the shear dimension, it is not able to withstand punctures as well as our stuff sacks and fanny packs. The tarp should last many years with careful use and deliberate selection of campsites free of falling branches, thorns and the like.

The tie-out reinforcement patches are made from one piece of 2.92 oz/sqyd Dyneema Hybrid Fabric to provide excellent strength and durability. The tie-out patches are a staggered fan design, similar to a racing sail, evenly distributing the stress under load. (Inside patch radius 3", outside 2").

Tarp rigging is included in the price.  Lineloc V's are used at all tensioning points and are the only adjuster that can be used effectively with the ultra-thin 1.3 mm Z-Line.

The guyline is double-wrapped within the tensioner for greater grip but you can single wrap them if you prefer quicker adjustments.

The ridge trekking pole loops and ridge tensioners are attached to the tarp with D-rings so you can remove them if you prefer to use titanium adjusters like Tarp Flyz, Stingerz, or Waspz.

The 4 corner adjusters and the 2 center-wall adjusters are permanently affixed but if you would like to use your own rigging/adjusters, please email [email protected] and we will send you the tarp with the reinforcement patches separate.  If you go this route, please allow 72 hours after attaching your hardware with the included patches for a properly cured bond. All stock tarps are shipped already cured and ready to use.

This tarp folds up perfectly into one of our Small Ultralight Stuff Sacks (not included). If you are good at rolling/folding, you could definitely fit it into an Ultralight Drawstring Stuff Sack. We prefer not to stuff-pack the tarp, as the thinner films found on this Dyneema variant will last longer with fewer creases.

This is a very involved and time-consuming build, please purchase your tarp at least 1 month before any planned trips. 

For more information on specs and setup, see below. Refer to the images to the left for a comprehensive display on the effects of different lighting conditions and 6 months of use on the color of the tarps.  Colorways will appear more saturated and opaque over the life of the tarp as it creases and crinkles and loses it's transparency.

Returns are possible on a case-by-case basis and the price includes lifetime repairs, within reason.
