Here’s my conundrum on the subject. Breathable vs non-breathable or put another way Gore Tex(or equivalent) vs PVC.
If you only care about waterproof there’s nothing better than PVC coated material. If done correctly it’s actually waterPROOF. The Alaskan commercial fishermen are using heavy duty versions of this like Gage or Red Ledge. check out this site: http://www.americanworkwear.com/Rainwear-s/144.htm
That’s a big difference from water resistant. Waterproof breathables like Goretex are really water resistant. The rate them by waterproof up to a certain point. Even the best 3 layer Goretex will let water through under the right conditions. Say for example an all day soaker at Rainy Lake.
for the $125 range and breathables look for proprietary waterpoofing. Everyone seems to call theirs something different. Make sure it’s seam sealed. Sorry, no experience on the Frabill. Most of my stuff has been skiing/climbing/hiking type companies like Marmot.
