I have been an admirer of Henry Shires Tarptents for a while, in particular his recent additions to the Tarptent range, including the Tarptent Moment, and when one became available in in Denmark, I had no hesitation in buying it. However, as the Moment arrived I began to read a very long thread on BPL.com about the Tarptent Notch, a lot what I read about the Notch was appealing in particular its similarity to the Moment but without the need to carry extra poles, I was now torn between two options for summer in Lapland. So the obvious was to have both and test them in the demanding conditions that Denmark and Southern Sweden have to offer, each of which in no way will simulate conditions in Lapland. Thus this is a report of my comparisons of the two shelters.
Firstly the technical stuff:
Weights Tarptent Moment 877 gms. (with optional liner 1014gms) Stakes(pegs) 48 gms. Total 925 gms. Tarptent Notch 750 gms. Stakes(pegs) 66 gms. Total 816 gms. MLD DuoMid 526 gms. Stakes(pegs) 100 gms. BPL UK connector 46 gms. MLD SoloMid Inner 260 gms. Total 932 gms.
Notice how the weights for the DuoMid soon add up, as well note the extra pieces carried to achieve a bug free environment in the summer in the DuoMid. So form a simplicity point of view either the Notch or Moment appeared to be better than the DuoMid, and the Notch provides a saving of approximately 100 gms.
Weight is important but so is sleeping space and protection from the weather, looking at floor areas next;
Floor Areas Moment Sleeping 18 sq.ft.; 1.62 sqm. Vestibule 11 sq.ft.; 1.02 sqm. Notch Sleeping 15.2 sq.ft.; 1.412 sqm. Vestibule 12 sq. ft.; 1.12 sqm. MLD DuoMid Sleeping(solomid inner) 17.5 sq.ft.; 1.63 sqm. Remaining floor space 27 sq.ft.; 2.5 sqm.
Area wise the DuoMid has the largest footprint, however I do find that towards the sides the space is less useable, whereas the Notch and Moment have more useable floor space because of the struts at the end and the steeper sides. Therefore, living space is about useable space not just floor area. I normally use an Exped Syn 7UL which I have used as a base to measure the heights from the centre of the mattress to the centre of the roof of the shelter as well as at the ends of the mat, these are given in the diagrams below, along with the measurements for the floor length.
Heights above sleeping Mat Moment Centre height 84 cm. End height 43 cm. Notch Centre height 90 cm. End height 38 cm. MLD DuoMid Centre height(inside solo mid inner) 114 cm. End height 20 cm.
Henry lists the Notch as 3 to 4 season and the Moment as 3 season shelters respectively, I am not sure how he determines the rating apart from his extensive experience I assume.
My observations to date. I have used both shelters for 4 nights, though each in different conditions, however, with Niels using his Moment while I used the Notch on our last trip along the Hallandlseden it enabled me to compare the 2 shelters in the field.
Condensation: both shelters had condensation on two nights, however, the difference between the shelters was; in the moment the condensation is in the sleeping area, whereas the Notch the condensation was outside the inner netting at least limiting the likelihood of the user touching the damp sides.
Sleeping space: the netting inner in the Notch is smaller than the space in the Moment, thus there is less space to move around, the width of the notch inner fits the Exped 7 UL with a little space on the sides at the centre as well as some space at the ends.
If you were confined to a shelter in bad weather then the Moment would have more internal space, however, the twin vestibule options of the Notch ensure that you can have a wet and dry area.

Exped mattress and Aarn Featherlite Freedom in the vestibule of the Notch, and there is still another vestibule on the other side.
Poles, if you use trekking poles then it would appear that the Notch weight wise is a better option, however, if you do not use poles then the Moment would possibly be a better option. On our last trip we had little chance to test the wind worthiness of either shelter, though the Moment is capable of withstanding strong winds, according to several users on BPL.com. Likewise it would appear that the notch with its low profile is wind worthy and with the addition of guy lines through the vents to the top of the poles I would suggest that the stability of the shelter in cross winds would be improved.
Perhaps one of the best aspects of the Notch is its two doors, both can be opened for views, for breezes, or alternatively one can be opened the other closed. I spent a very pleasant evening at Mästocka watching the sunset from inside the Notch.
However, while camped at Mästocka I also noted that the "floating floor" on the Notch may be be problematic on sloping ground where a lot of tension can be placed on the elastic connecting the inner to the outer, if the floor moves.
One more thing, the inner can be completely removed on the notch and thus the notch could be used with a bivy or not, thus lightening the load even further, (the weight of the outer only is 430 gms.) One of these two shelters will accompany me to Lapland this summer, I am still deciding on which one.
Basti raised some interesting questions about packability of the two shelters. So I have added this addendum, with a photograph comparing the two along with a Nalgene bottle. The packed lengths are given in the table below.
