Bought this tent just over 3 years ago but has only been used twice prior to last year. First time my son camped in the back garden in 2021 where it was up for two nights, then once to a music festival weekend a few weeks later. It hadn't been used since the music festival and was always put away bone dry. Went camping last year (2023) having been stored away for 2 years under my son's bed. The blackout coating is now all coming off in what feels like a sticky gluey mess. If you touch it, the blackout coating comes off on your hands like black tar allowing the light to shine through and it's a nightmare to get off your hands or clothes should you accidentally rub against it. After a bit of research it turns out this is a known issue with the material used to coat the inside of blackout tents which starts to break down and disintegrate after a couple of years or if it's been stored in a really hot place. I wouldn't class under a bed as an excessively hot place or extreme conditions. BTW this is not an exclusive issue to Coleman tents but the blackout coating used on ALL tents which is why so many manufacturers stay away from making blackout tents. My advice is to avoid if you're planning to reuse your tent or keep it for a few years. If you're only planning to use it once or twice then throw it away then you might be OK. This tent is great, quick and easy to erect and feels really warm. The red colour really goes with the black and feels cosy and (when it worked) the blackout was great especially for festivals when you want a much needed lie in after a late night/early morning and on hot days it really does help to keep it cool. Having said that, we went away last summer and found that sometimes the blackout can be a pain when trying to find stuff in the dark or get dressed when you can't find your clothes or your phone charger etc. Plus we're rarely in our tent during the day to worry about it getting too hot. Can't say we noticed much difference at night between our non blackout tent and this being any warmer. I so much love this tent for a short two person getaway or a festival but if I was going to buy one now I would seriously suggest getting the same tent in the non blackout version. It will last a lot longer and be more practical so you're not scurrying around in the dark in the middle of the day having to use a torch to find your car keys. The last time we used it, we had to withstand 3 days of torrential rain and it didn't leak once. This is one seriously robust tent. We also purchased a Eurohike tarpaulin to go over the front which gave us a bit more protection from the rain as there's not really anywhere to store cooking equipment or chairs which I would say makes this tent even better if your planning to store things outside. As usual, ignore the person size. This will fit 2 adults comfortably lying side to side and that's about it. The only way you'd fit 3 or 4 people in this is if they were kids or under 4ft tall. This tent will fit a standard double sized SIM in sideways as per the photos. Had a couple of great weekends in this tent but my advice: Consider the green non blackout version first. Happy Camping!
