I too have the ASAT 3d suit along with the ASAT coveralls and archers jacket.

None are insulated or have sent loc but you can wear anything you like under the 3D suit and even go naked under it if it is hot.

I am very impressed with the ASAT gear that I have it has helped me take my first deer.
You will find that ASAT wont get that blob effect that some other kinds of camo get.

The ASAT camo to me seems to take the color of what ever is surrounding you so if you are in a green thicket then the suit appears to be green and blends right in.

I know I for one wont be changing from ASAT for a very long time.

Chuck and Tim are 2 great guys who back up their product Chuck has even called me and gave me his personal guarantee on the suit what else can you ask for.

When I was camo shopping Bill Jordan never called me to give me his personal guarantee on realtree camo.

If you like send Chuck an email and ask him what you want.

You will find that he will bend over backwards to help you.
