So, among the "Extreme" compression category, their highest level of compression and the only one I can see being of use to most trans guys since the rest do less than an ordinary sports bra for me, they still have the old Tri-top (which is the crop top) and Chest Binder Tank (which is the long undershirt.) These are exactly the same as they were years ago.
But they've also come out with this new "cotton" lining, which is actually closer to microfiber than cotton in terms of texture, but wicks sweat a little better than their original material and is less scratchy on the skin. So there's the old material on the outside (which is why all the photos look the same) but a different, softer lining on the inside. The downside as that they don't bind quite as well, though they're still better than gc2b in terms of binding power. The "cotton" equivalent of the Tri-top is the Cotton Lined Power Chest Binder. The "cotton' equivalent of the Chest Binder Tank is the Cotton Concealer Chest Binder.
They also added a bunch of stuff in the lower compression categories. But again, anything that's not in the "extreme" category is kinda useless.
Personally, I definitely prefer the new cotton-lined stuff, because it cuts way down on rash issues in the summer.
