I just got my Guide Gear bibs a couple of days ago...Loved them except that they were too small.I'm 6'0 260 42" waist about a 31' leg in Levi jeans.The bibs did'nt fit my gut,could barely zip the ,forget about layers,and the other thing is the way they fit on your "trunk" was getting a wedgie trying to pull the up and the bib part barely came up to the bottom of my tits!
It is/was my first pair of bibs so I don't know if this is how they are supposed to ride???I sent them back and ordered a set of Arctic Shield bibs in 2x.Got them today and the fit much better but the crotch thing seems to still be going on,must be me although it is 100% better.I loved the Guide Gear bibs,material seemed tougher ,but the Arctic Shields are 100% warmer.
