It was originally sold as an Outdoor Designs Ridge Raider, and it’s supposed to be a very breathable version of Goretex so you don’t feel as if you’re on the verge of suffocating (which was the case with early Goretex tents)but Rab may have taken them over.
It’s fine for one person, I’ve had a 40l bag in there alongside me plus boots etc on my other side but if you use a top spec Exped the roof is very low and in hot weather you need to keep the inner door wide open because as is always the case with Goretex the fabric works best when there’s a temperature differential. I’ve used it in temperatures down to about -5c and there was no frost or condensation inside but Richards nephew might not go cycle touring in mid winter
Edit: I’ve just wasted 5 minutes of my time and the Outdoor Designs tent in the photo uses Goretex Exchange fabric which is supposedly better than eVent but more expensive and the same parent company own Outdoor Designs and Rab.
