Well done both sides for finally joining up. Simond kit for especially winter climbers is very popular.
Indeed, never thought I'd see the say.
Has renewed my hope we might one day see some Decathlon gear in the group tests.
Interesting.
Simond claims that the single‑walled tent limits condensation in a way that they are trying to get patented (there is a lot of prior art though, we'll see). So I had a look at the patent.
Basically they use thin film deposition to sputter a metal or metal oxide (likely aluminium) onto the outer part of the flysheet.
The metallic thin film should have much lower emissivity than white plastics, so it shouldn't cool down as much as normal plastic at night due to radiative cooling (hopefully also not in the atmospheric long wave infrared window).
Lower emissivity, less radiatively cooled fabric, less condensation on the inner side of the sheet. At least that's the premise here.
Obviously won't work 100% of the time, depending on the conditions, and Simond themselves admit that. But even if it helps a bit that's nice.
My WASG is it'd mainly help on colder, clear summer nights, where lessening any radiative cooling might just about bring the fabric above the dew point. Go further below zero (but who would, in a summer tent) or in a cold sustained rain, probably not so much so.
Would be nice to see an UKC review of it in the UK weather!
Back in the day I had a single skin goretex limpet tent made by IIRC Snowdon Moundings. The goretex had a slightly furry yellow backing which held condensation, and I don’t remember condensation dripping ever being a problem. It was a good expedition tent, although a bit heavy by today’s standards, and once I’d sealed the doorway seam it worked well in Llanberis rain too!
It's clear in the article that the tent is a summer backpacking tent. I've used bivi bags in cold UK weather in the past but never again, it was like rain pouring down inside the bivi. Perfectly dry on a breezy warm night.
