I woke up around 1am cold and an aching hip lolMy Trekology UL80 also failed on me this year when in France. I replaced it with one of these from Decathalon in Colmar https://www.decathlon.co.uk/p/light...e-xl-mt500-xl-195-x-60-cm/324600/c221m8853281
Really happy with it so far.
In the morning when i had the light i checked under to make sure i didnt lay it on something sharp, couldnt see anything.
Maybe just coincidence but its the first time i camped without the tents groundsheet.
