I'm pretty new to this forum and also relatively new to hiking. I've been searching and browsing various topics and finding alot of useful and entertaining reading!!
So I'm considering buying a Sea To Summit - Thermolite Reactor Compact Plus to compliment my cheap (never before used) +5deg rated synthetic sleeping bag (purchased from Anaconda

The bag is 225 cm long by 85 cm wide and the liner is 183 x 90 cm ... so my silly question is will this liner suit any (my) bag or do I need to buy a liner that matches the dimensions of my bag??
This is the liner:

Thanks for your help.
