I so wanted to fall in love with these bibs, but just can't. I ordered a Large (5'9", 147lbs, hips measure 39"), but could barely pull them up. These were the 12-hour chamois bibs in the outlet, which weren't returnable, but talked to a Patctimo Ambassador and was able to exchange for the XL, which fit, so I'm wondering if the original pair ordered was mis-sized? Thank you, Pactimo for allowing me to exchange them! I've worn them twice, once on a 35-mile ride and today on a 45-mile ride (2.5 hours of riding). They left me sore and wishing I had my other bibs on. I'll wear them on shorter rides, but definitely won't wear them when I'll have more than an hour in the saddle. The quality of the bibs is excellent, the chamois just doesn't work for me.
