My first pair of bibs, and I wish I had converted sooner - I warmer and more comfortable. Patagonia really nailed it with the Powslayer's.
I've always loathed trying on ski pants, it's like trying on jeans, too tight in all the wrong places, too loose in other spots, but I was surprised to find that the fit here is spot on, maybe a touch roomy. I purchased a Medium, I'm 5' 8" 150lbs, wear an 8/10 in most pants, bigger in the hips, narrow, high waist. These have plenty of room around the hips and thighs, are tailored to be feminine around the waist, but roomy enough for a couple of layers.
Oh the ease of getting your pants down when you have to go. The two snaps on either side are super easy to undo with gloves and the panel unzips with ease. The side zips work in either direction to allow back of the knee venting. Pockets on the legs are wide enough for a big phone or trail map, and pockets at the waist are perfect for a pass or cash. The bib straps are Velcro, so very adjustable, and the circumstance at the bottom of the pant leg is wide enough for a snowboard boot.
Been out and about in these on storm days, sunny days, touring up hill, and riding lifts. Thus far, STOKED. Note that these are single layer pants, on really cold days your going to want a thicker layer underneath. I've been using Arc'teryx Phase SV bottoms for most days, planning to find something thicker for low temps and to keep the bum warm are chilly lifts.
