I agree with fatlander.
I have both the Stratus and Sanctuary set.
When it dips below 32 in the morning hunts I'll wear the Sanctuary.
The Stratus jacket is the weak point in the system in my opinion. It's pretty much just a shell but is wind proof.
It's also not cut to have several layers on...
Y'all and your 60-80#'s bags ---- spartan.
I found 40# bags of cat littler are cheap. Wrap it with duct tape for added protection and to keep it in a "form".
You can also find them in 20 and 30#.
You can add weight from there with other things.
