I had a set, and the pants leaked like I'd been swimming. Something in that crotch panel not done right or something. I also found them extremely hard to put on, with the lining always catching on my boots. I did like the jacket, though.
Before the Sentinel I had a Defender, also from Tour Master, tore it up in a low-side, and I got another Defender to replace the Sentinel. The whole suit packs smaller than just the sentinel jacket, and has a carry case so there's only one package instead of two. And I've never gotten wet inside the Defender.
As for the packaging, here's the Sentinel, jacket on the bottom, pants above. Pants come with a carry pouch which has a snap strap to attach to the jacket, keeps them together.
As I said, the Defender packs jacket and pants in a bag about the size of the lower one.
