Looking to buy some simms waders but not sure which one to get need them for winter flyfishing and duck hunting any recommendations need 3x if they make them ?

Love em. I have the Freestone pants, and the Headwaters chest waders. The Freestone have been flawless, but aren't Goretex. The Headwaters are 3 layer Goretex, but I tend to wear the Freestone pants more often just because I generally don't wade chest deep that much. Also wear them when kayaking in cooler weather. If either eventually fail, I'll get a pair of the G3s. But they are still going strong for 3 years+.

I do wear them when I duck hunt. Just add a base and mid layer pants, and you should be fine. Looks like they do make them in 3xl and they also do custom sizes, but you'll pay for that. Simms customer service is also top notch.

I have and currently use a pair of Bass Pro Light weight waders. Like BoPro said I just throw on a pair of silk weight long johns and a pair of sweat pants and go out. I have used this set up for years in Colorado fishing anywhere from -11 to 30+ before I ditch the base layer. Above 50 I just go with shorts and the waders.

The G3 Guide are supposed to be some of the toughest ones, but lack some of the features of the higher end ones.
All waders have their issues, but Simms is top shelf along with Orvis and Patagonia.

My fishing buddy & I both have Simms G3 stockingfoot waders, which are over 5 years old. They've given us great service with no leaks especially around the seams which are usually where a set of waders will fail. We would buy the G3's again should the necessity arise.
