I have G3s. Best waders I have ever owned, end of story. I’ll never buy a different brand so long as Simms keeps up the quality. In fact, I don’t really know when I’ll even need a new set, because they hold up so well.
I owned a Outlaw X5, not a frameless model, but I can vouch for the quality. They took a while to ship it to me, but it was a great boat and put together really well.
Just for another opinion, last fall I decided I wanted to replace my Scadden pontoon with something I could safely bring my two little boys in when I fished.
