wool

I have 1 pr. Sleeping Indian pants worn once bought new. 1 pr. King of the Mountain pants used some repairs and a couple holes, it has been hemmed guessing to a 29 inseam. Still very warm. 1 King of the Mountain archers shirt? not sure what model it was. It's been worn a bit but in great shape...

Does anyone have experience with the FORLOH Deep Space base layers? How do they stack up to 260g/midwieght wool base layers ? My wool base layers are on their last leg and I am looking to replace them with something made in the USA. thanks,
