I bought a 2XL in the Trekker bibs. I'm 6'!" and 250ish. I bought mine in store so was able to try it on. They told me the Predator runs smaller so I would have needed to buy a 3XL but they didn't have any in stock. Didn't try on the jackets so I can't help with sizing. From what I've read, there are very few complaints about the Striker suits and their features. Most of the ice fishermen up this way wear Striker gear.
