Im off of SWAT now, so I dont have to worry about size so much anymore. When its cold enough to hunt around here, I generally have enough clothing on not to worry about a mat if I end up having to should off of the ground. Just not down long enough to worry about it.
Ive been through my share of GI sleeping pads, and cheap imported mats. I will never have another shooting mat(TAB, Triad or otherwise) with plastic buckles. I think I have three mats around with one or both of the straps that have broken side release buckles. No matter how hard I try to avoid them, the buckles always get stepped on and break. TAB mat with metal D-Rings or Triad with metal hooks from here on out.
For trips to the range/farm to shoot, I now use the Triad Mat because its padded.

It is more comfortable than the TAB(hey its padded), but if size is an issue its twice the size of TAB and weighs 2.5 lbs vs. 1.5lbs of TAB. Working out of the trunk at range, or if the hike is short, I'll stick to the Triad mat. Any time where size and weight are at an absolute premium, TAB still gets my vote.
Rumor has it their slings are good stuff too.
They offer several models to choose from. Rifles Only carries even more TAB sling options than Triad does.
