Decathlon Quechua - MH500 Roof Tent

Décathlon : Quechua MH / SIMOND MT séries = incredible value for money. Price starting at 30€ up to hundreds.

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.

I have decathlon fresh&black tents and they are the best, you can sleep around 2 hours longer when the sun comes out and they are relatively cheap while beeing of decent quality. I don't know if you can get them in the states though.

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.

Get a Fresh and Black from Decathlon and call it a day. It’s by far the most acclaimed series of tents on here.

Decathlon tents are solid for the price, but only certain models are really light enough and compact enough for backpacking. The fresh and black tents are good if you have difficulty sleeping, or perhaps you have small kids and need to encourage them to sleep. Personally, they’re not really my thing because I don’t like needing to use my headlamp in the tent in the middle of the day, and I love the feeling of waking up with the sun when camping.

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.
