Arpenaz 5.2 F&B

We got a 5.2 this summer, used it Times and it's been great. We've got 4 different tents of different brands do we've got a lot to compare against and would definitely recommend it

So I have that fresh and black tent and IV used it 3years at download and a separate camping trip.. Download it was just for me and all my gear and it was so spacious.. no bother at all. It also survived the great rain of 24' with absolutly no leaks, and I can actually put it up on my own which is a win! IV just bought the bigger version for this year because my 6ft 6 partner is coming with me and I wanted to make sure he had ample feet room 😂😂 but I wouldn't buy any other type of tent now.

I've got one of these, stays really cold in summer, and you don't wake up with sunrise at 5am

Throwing in another rec for a blackout style tent, keeping sunlight out does a lot to keep the temperature down. I've been happy with my Decathlon Fresh & Black tent, I know Coleman also has some blackout models. You could also add a battery powered fan inside to increase airflow.

The setup that tends to work for sleep in the day, shoot at night is a system, not one magic tent: a blackout tent (Coleman Dark Room or Decathlon Fresh&Black), plus an external shade tarp/canopy pitched so the sun never blasts the tent fabric, plus airflow (at least one quiet 12V fan) and a sleep setup that runs cool (cot if possible, light quilt, breathable pad). Site choice matters as much as gear: grab natural shade, face vents into the breeze, and keep the rainfly high for ventilation while still maintaining darkness. For CPAP, run it on DC with the right cable, avoid an inverter if you can, and assume you'll need more battery than you think, especially if you use humidification. Also plan electronics protection: keep camera gear in the shade, in an insulated tote, and out of direct tent heat during the hottest hours. Done right, you'll actually sleep, not just survive until sunset.

Decathlon's Fresh&black line is designed to prevent it from getting hot in the summer. It will not keep the temperature low throughout all day, but will surely keep the night's cool longer as it has white reflective material outside and some aluminium insulation. They also have some additional vents added.

I'm not sure if you've got a Decathlon in your country, but they can help you with this purchase. They even have their "fresh and black" tents which stay cooler when the sun hits the tent (worth gold at a festival, basically everybody has these at festivals in my country). Apart from that, I'd get a cheap simple tent for a techno festival. Look into getting a 3-person tent to have some room to store clothes inside it if you are with 2 people and get a tarp for some dry-ish cooking space outside ("3-person" means: 3 sleeping mats will barely fit next to each other in the tent with no room to spare). Tarps can be a bit more difficult to set up properly, but easier to carry than a party tent (which would be your other option. The most lightweight option is to just find some people that brought the party tent and make friends with them. Just take some stuff you can trade for a space under the tent. Actually, thinking about it, just buy food at the place instead of cooking yourself. The festivals I went to hardly required cooking. But I guess that depends on the festival maybe. OK what festival are you going to? Maybe I can watch some footage and tell you what tents people were using there.
