2 black button-type snaps on the front panel allow closure from inside, releasing tension on the zipper. A third snap is located at the foot of the same panel

If needed, the attachment clips shown on the interior of the shelter can support a biv sack netting away from the user’s face- as well as use for inner mesh net

next to the top of the trek pole is the black, small plastic clip which allows hanging of the inner mesh net- I connect this to microcarabiners to prevent damage to the clip

The Duomid ($440) arrived 5 weeks and 3 days after ordering online from MLD.com, located in Roanoke, VA. The shelter weight is 14 oz for 1-2 persons; I will be writing separately about the modular, Solo silnylon inner tent which hangs within this shell as needed for insect protection ($175).

The tarp was sent with a 10 cm= 6 in pole jack, which extends a standard trek pole if needed for a taut pitch. I find that to pitch near the ground, my 130 cm trek pole alone can work but the pitch is probably more wind-resistant using the extension. I use 12 stakes as standard. The shelter has 8 ground-level tieouts and 8 mid-tieouts, with a peak hang tieout=17 total.

With the option of hanging the tarp from its apex if desired, no pole or stick needed in appropriate locations.

There’s a great deal of  covered space – over 45 sq ft- a palace for one with a huge covered vestibule… I would be fine using for 2 so long as the conditions were not very wet, because one person would need to cross the other inside.  The peak vent is well designed including an integral stiffener, and can be completely closed if need arises.

Being made of Dyneema/cuben, this shelter is extremely light and does not absorb water, with almost no stretch after pitching.  I like that there is adequate privacy, but at the same time I can judge weather as it is translucent and do not need a dedicated window built in.

I will be treating the one front door zipper with care, including closing the base buckle before operating it to reduce stress. I opted to use Zip Care lubricant as well, available from MLD.
