For sure. I remember when I first started doing nights, I used this horrible Argos wire framed sun longer, a cheap 70's brown and orange summer sleeping bag that my Dad gave me, this absolutely useless leaky Nash bivvy thing that cost about 60 quid new.... not necessarily because gear wasn't available but because I couldn't afford anything better. I'd be absolutely freezing, regularly caught colds, ate and drank complete rubbish as I had no stove lol.... I DO NOT miss those days!
But you wouldn't catch me dead using one of these Nash path things!!
