To be effective in MilSim in winter, keeping warm will always be paramount. In episode 150 of November Foxtrot, they touch oh this topic... "This is part 2 of our winter MilSim episode!

Winter is coming and we will be chatting about bits of kit you might be interested in to keep warm. Whether it's dashing around the field as QRF or standing on STAG for 2 hours - no one likes being uncomfortably cold ... and you can't always rely on cuddling up to your pal for warmth!"
