One of my favourite things in the summer is heading out to the coast to go camping and soaking up the glorious sunshine; one of my least favourite things is waking up with the sunrise at 5am and by 8am feeling like I am trying to sleep in a sauna. The Mackenzie 4 BlackOut tent from Coleman features their BlackOut Bedroom design; this clever bit of tech blocks out the daylight, keeping the sleeping area cool in the daytime, up to 5°C cooler in fact.
