Perfect Fit

Great pockets but tough zippers
Love the multiple zippers and ways to get this on and off. Pockets are roomy and well placed too. Knocking down one star because the zippers are tough to pull, especially with gloves on. The fabric also stained really easily from mud the first time I wore it.

Love the fit!
I am so excited about these!! As someone with larger thighs it has been impossible to find bibs that fit without being either too tight on the legs or massive around the torso. These are exactly what I’ve been looking for- plenty of pockets and extra room to move around the hips and thighs! I would say they run a bit big - I am usually a size large in many brands but went with a medium here. For reference my measurements are 29” waist, 43” hip, and 26” thighs.
