I've been using the LL Bean Rapid River waders for a couple months, and they're perfect. I bought a pair of Simms Headwaters, but the fit was funky. I'm 6'1" tall, wear a 34" inseam, a 12-13 shoe depending on brand, and weigh 190lbs. The large size Rapid River waders fit extremely well:no saggy butt, baggy legs, or cavernous chest section. The neoprene feet fit very well, and are well-built. The entire pair of waders are well-built, and dare I say built as well as the Simms?!?!?!? The Simms
had five-ply on the front section of the leg, and Rapid Rivers have
5-ply around the entire leg, and a bit up the rear seat. They look nice in the catalog, but look fantastic in person. The legs are made up of a few sections of banded material (if that makes sense), and the leg articuation is better than the Simms. I love them, and had planned to write a little review here.
The Rapid River's waist built has three loops to hold it in place, and is light years better than the Simms Headwater waist belt.
The shoulder straps are more narrow than the Simms, but they also don't feel bulky. I prefer them to the Simms. On Bean's website, the reviews are about 50/50 for leaks: half have never had any kind of leak, and the other half say there Rapid Rivers
leaked out of the box, or soon therafter. I've waded up to waist level many times, hiked in them, and walk through some nasty thorns regularly. No problems, and the fit is so good that I forget I'm wearing waders. The 5-ply legs are very tough, but very comfortable. The Simms were very difficult to remove: my foot was too large for the narrow neoprene to GoreTex section. That had to be the worst part of the Simms.....
