I have the vex bibs and like them for the last 2 years. wanted Striker Bibs but just didn't have the monies at the time and my wife got the vex bibs for like $75 at Christmas.
If you are looking for the best I'm voting Striker Predator too
I bought the strike predator bibs a month ago. Was on Winnipeg over the weekend. Was -17 with a 20-25 mph wind and the bibs worked great. Now that I have them I'm glad I spent the money on them!
I run striker as well. I've run other ice suits in the past and the Striker is head and shoulders above all of them. I run predator bibs and a Striker Climate jacket.
I find the Striker stuff to be the least bulky stuff I have worn. It is definitely better than the Clam and Sportsmans Guide Ice bibs I've worn in the past.
I have Frabill I3 bibs. Have only wore them a few times and so far I really like them. They are on super sale most places right now. Prices vary by size/color. I paid about $80 on amazon.
