Hi guys! This is my first post on the forum, and I have a question about the upper limits of sleeping bags. I'm looking for a sleeping bag, but I can't decide between aegismax nano-L (574g, comfort: 10 °C) and nano 2(M:624g or L:742g, comfort: 5 °C and looks to have a better construction). I will use it mainly in the summer in Portugal, where the temperature is well above the comfort temperature of both bags(>15ºC). I'm also planning to buy a silk liner for warmer nights. Maybe, I will try to sleep on it during the winter in the south of Portugal, with night temperatures of 9-10C. So, how many degrees above the temperature rating, according to your experience, can you sleep comfortably before you start sweating? And what sleeping bag do you recommend me to buy? Sorry for my English.
