Sorry tedw, but that's a definate wimp trait.
I wore them for years, even when doing CFTs, :AR15firin etc. And when am I going to be doing that again? Not in the near future.
It's not about being "army barmy", for me, it's about being warm on a budget, and you have to admit, the shirt, layered with other kit, would fit both.
As for the Swanni shirt - I always thought they were very expensive for what they are. Just MOHO, but I'll have another look at them.
