Just received the Redington sonic pro pant as an early Fathers Day gift. I figured I'd throw my two cents in for those who may be looking for a similar wader. First thing first I was attracted to the Sonic Pro technology due to the fact that they are welded rather than stitched. So I researched all the different "pant" models available and was surprised to see that many of the prices are not much less than a full chest wader. I have always been a Patagonia guy but I'm open to try anything. In my research I read many good things about the Redingtons but the price being approximately $100 cheaper than many others I was left skeptical. After much consideration, I finally decided on the Redingtons as they were to serve me more for summer small water and backpacking. To start with, getting them out of box it was nice to see they come with a mesh storage bag and they felt lighter than expected but the material did not appear to be compromised. Tried them on and they fit almost perfect in the large just a tad long but that's no big deal for me (I'm 5'10" and weigh 220). The neoprene socks on the waders fit almost perfect and do not a lot of slop the way some other waders I've used do. The hooks on the gravel guards seem stout and plenty capable though being made of plastic. There are both adjustable Velcro waist straps and suspenders which is nice if you have a preference. Now for a field test. I chose to break these things in not too delicately. I picked a spot that involved biking on gravel, hiking on trail and severe bush whacking with a menagerie of vegetation that my exposed skin didn't fair as well as the waders did. They proved breathable enough for heavy exertion and so tough mowing through deadfall, blackberries and alders on very steep (and I am a climber as well) terrain to get to the stash that I would be testing the waterproof capabilities on. Once on the water I had no issues at all, again these are very comfortable and feel as if they move with every step or lunge or pedal. All in all these appear to be a very solid choice especially for anyone who fishes skinny water or backpacks. If I could recommend one thing to Redington though on these, it would be to put one more layer on the seat and knees just for piece of mind. Hope this helps.
