Please help me choose a tent

Priorities (in order):

Performance in Rain/humidity – I hate worrying about getting wet.

In my experience, a small 1P tent in the rain is miserable.  I’d stick with 2P.

I have and sometimes use a Nemo Firefly 2p freestanding tent. If you notice that cut on the fly,  not sure if its same as on Dragon fly tent,  but if it is.. It has not been an issue for me, even in heavy rain. 

Yeah that was my though RE 1p or even the 1.5p tents. Here is the list filtered for 2p tents.

I am close to pulling the trigger on a Revolution or the Portal, but am being picky on fly material. I have read that the sil/sil nylon these two use sag less than what I am probably used to.

Have you looked at the Six Moon Designs tents? I haven’t read super carefully through all the details in your post, but some of them might work for you? And they seem very affordable.

I had a 1-person BSI Mirage. Great tent, but condensation at the foot and head was hard for me to manage. I understand that BSI is currently updating the design to include a “DripDrain system” at the ends, which should help? Anyways, I’d recommend going with the double wall Revolution if you go with BSI.

Otherwise, Slingfin Portal is outstanding and the build quality is higher than BSI.

Thanks Alex. Have you used the portal too? How would you compare the rainfly material to the BSI SuprSil?

Yes, I have a Portal 2, but only used it on one trip so far. 3 days/2 nights, shared with a friend. We did get rain, hail, and moderate winds and it handled it well.

The rainfly material feels thinner than BSI’s. Otherwise, both seem to perform about the same (e.g. stretch, sag, beading of water).

Please note that the Slingfin fabrics are nylon, and I found the fabric to have the issues consistent with nylon tent fabrics.  If that is not an issue, one of the lighter slingfin fabices may work for you.

Zpacks introduced a new freestanding tent that you might want to check out:

Free Zip 2P Freestanding Tent

I own the predecessor to this tent, the Zpacks Free Duo.  I’m satisfied with my Free Duo.  My only gripe is splashback during rainstorms because of the short vestibule doors.

The Big Agnes Copper Spur 1P is a stellar tent, and I find it fairly palatial for a 1P. I have used one in a variety of conditions including “light winter” as you put it. While it primarily has a mesh interior, it has a thin fabric at the lower portion of the inner to block wind. A nice compromise really. I don’t currently own one, but if I was looking for a freestanding 1P tent for everything you describe, that would be my top choice. Ive had two of them.

Dragonfly – This was my original choice. The cutout in the rainfly is the main thing holding me back.

Aside, I wanted to address this – I’ve used a Nemo Hornet 1P going back to 2016. It’s handled all kinds of hellacious weather admirably, even though it’s not technically a freestanding tent. If you really want the Nemo, I wouldn’t worry one bit about the fly cuttout. It’s just not a “thing” IME. In fact, I replaced my original Hornet with the Hornet Osmo Elite 1P. This year my wife and I replaced our BA Copper Spur 2P with a Hornet 3P too.

OK, so you may want a silpoly dome, but may have to wait a while until TT comes out with the silpoly arc dome.  You can sign up for the TNT arc dome on the TT site; but it is a nonwoven, though better than DCF, or so TT thinks, as I do also; TT says the TNT will be better than DCF and less expensive.  How much remains to be seen when TT starts selling.

Most of the so-called domes use the hubba type design, which means hubs and struts that don’t lend themselves to strength in blows, and add to weight.  The TT arc dome uses full length flex-poles which are stronger, and pitch faster.  Since the flex is less pronounced, it may also work with carbon shafts that run 0.247  oz/running foot, much lighter than Easton’s best alloys.

You seem to have ruled out most of the other domes, so it may be worth waiting for the arc dome TNT, or even the silpoly.  I use Australian tents so am in no hurry; but you may have to settle for the TNT or even the silpoly that appears to be slated for even later for the arc dome.  Some dislike the lesser pole flex, due to less inner space; but compared to concave saggy A-frames,  are palatial.  And the lower flex pole design presents much less walls against the wind, so is far more aerodynamic; hence wind resistant.  It is a trade-off between inner space and reduction of wind force against against the outer walls.  T’wer me, I would wait on the TT Dome in the silpoly; or start looking at Aussie and New Zealand domes.  They’ve been coping with awesome wind blasts longer.

Granted, I am dead sent against laminated SUL unwoven tents.  They are not only outrageously expensive; but far less durable, as was shown on the Skurka sponsored trek posted on BPL:

The silpoly fabrics, with a mini-ripstops, are ideal, and are what I suspect some of the cottage makers are using on tarps.

The last ripstop polyester tent I had the fabric tore like paper.  It might have less sag when wet (one the many overused and repeated UL cliches) but certainly wouldn’t trust it over silnylon when it mattered in harsh conditions.

“Most of the so-called domes use the hubba type design, which means hubs and struts that don’t lend themselves to strength in blows, and add to weight.”

The main structural problem with the hubba type design isn’t the hubs and struts themselves, but that the two dual arcs quickly merge into a single arch for a large span, so it ends up behaving more like a single arc tent (e.g. weaker). In essence, it is a single arc tent with a little bit of extra support from the forked ends.

The hubs themselves are not the problem as any freestanding tent has lots of joints/ferrules (between the pole sections) and a hub is just a particularly robust ferrule joint (e.g. if you took a simple arc and added a hub in the middle, there would be no loss in strength). The cross strut also isn’t the issue, as it is an add on that doesn’t have much effect on the overall strength since the core structure is still there (e.g. the SlingFin Portal is a dual arc tent with a cross bar that is quite sturdy). It’s that merging of the dual arcs into a single arc for a major portion of the span that causes the loss in sturdiness. Theoretically you could use larger/stronger tubing for the single arc portion to compensate and make a Hubba style pseudo-single arc tent that is similar in strength to a dual arc, but the Hubba uses the same size tubing in the single arc portions so it does behave closer to a single arc tent.
