Long shot I know but having just been eaten alive on a trip under a Deschutes Cape I'm after a Six Moon Designs Serenity net tent.
No one has UK stock that I can see

Now then, faced with the prospect of death by midge the other night, I used a Sea to Summit Nano pyramid net under my Gatewood cape. Weighs less than 180g, can be had for less than £20, dead easy to set-up and kept me bite free ... might be another option worth considering?

Interesting. Thanks for that.

I tried a similar set up - the bug net has slightly different dimensions than the mesh inner so a bit of a fiddle but it worked, along with a groundsheet. The groundsheet and net weighed in at about 300 g's tho and the serenity mesh inner is 330 and has a nice deep bathtub ground sheet so I ended up with one and they do work well. Ali express do similar things for much cheapness and the right dimensions. (which I discovered after laying out £130 for the serenity inner...)

If I'm spending the cash I guess I'd like the bathtub floor as well.
It'd make the setup better in wet weather as well as bug weather.
Never seen Ali express. Maybe it's time I did...
