90 ptn sleeping bag or the British Army FESCA Modular Sleep System MEDIUM only

[MikeLA]

Always been a big fan of centre zips (hate mummy bags or side zips in the middle of the night).
Owned a 90 ptn for many many years but should I upgrade to the FESCA medium bag ? Is there any benefits weight, pack size, just looking at the medium that’s all

I use an old 90pat and love it.
As it (and I ) get older it is losing some its once excellent insulating properties.
It was called “all season“ but I tended to sleep on top of it in the warmer months

I’ve done two things:
Bought a Snugpack back up.
and
Got myself several liners for the 90. A thin polycotton one for warmer times and a couple of fleece liners of different weights for winter.

Here in England we winter campers know about climate change. It is years since I have woken up in a frosted tipi or cleared snow for the KK.

My old very slowly degrading 90pat is sort of adapting with the times as winters warm up
