Dogfish,

I fished in neoprenes year round for over ten years. I bought some Simms breathables two years ago and I haven't worn my neoprenes since. Probably never will. You'll roast your ass off in the summer if you wear neoprenes. You can wear breathables in the summer and hardly sweat a drop. I wear my breathables in the winter with a pair of Waterworks and fleece pants and it keeps me plenty warm. Oh, yeah. I have worn them probably 200 times and not one leak. Peace
