Use for cycling, 3-75 miles ride. They have the right amount of cushioning without feeling very bulky. The length is perfect, comes to mid thigh (I'm 5' 1 tall). The material really wicks moisture away from you. Just the right amount of compression. If you are in between sizes I recommend sizing up.
I was hoping it was a little more lightweight, to be used as a vest on cool starts that I can easily stow away once it warms up. It is probably a bit more robust than I initially thought, but I have found it great this autumn for rides where I put on the vest and never take it off. I'm a huge fan of vests, and this one is kind of in the Gabba territory in terms of weight and conditions, but it does pack down a touch better to be put in a jersey pocket if needed. Ultimately I probably did not need this vest, but at the price it was going for I could not refuse. I'm 6' and 165 lbs with a fairly small chest at 38 and the vest fits well over a LS jersey and baselayer. Snug, but not restrictive.
Its been years since Ive worn PI bibs. Ive been making excuses for being uncomfortable in the shorts that Ive been wearing recently. Too hot! No chamois cream, etc. No more! I can now do 30 and 40 mile rides, and Im comfortable. PI discourages the use of chamois cream. I was skeptical, but I am comfortable without it. The cuffs stay in place also.
