Sorpasso RoS Wind Bib Tight

When subfreezing temperatures come to town, the list of your basic needs moves into bold text with lots of underlining. Castelli aims to keep you rolling through harsh, winter base miles, regardless of the conditions with the new Sorpasso RoS Wind Bib Tight, which acts as cycling’s equivalent of a windshield and a deep-winter heater. GORE-TEX Infinium Windstopper fabric is sewn into the frontal area and thighs, providing wind protection for your quests down to 23-degrees F. Making up the rest of the RoS Wind is a mix of Nano Flex 3G and Xtra Dry to hold in the warmth while maximizing breathability and water-repellency from passing showers or sleet. Castelli claims these are the best tights fabrics they’ve engineered, and with sub-freezing protection that also breathes enough to perform up to 46-degree F, we certainly would agree.

Castelli uses the performance-tuned Progetto X2 Air chamois to help you with the extended base miles January requires, and the lie-flat bib straps with mesh backing add to the hours-long comfort you’d expect from Castelli. Low-light visibility is enhanced by the reflective calf stripes, which double as zipper guards.

I am 6'2", 190# and bought a XXL based on other Castelli bib tights I have owned in the past. Tights work great for rides mid 20's. Paneling on upper thigh is Gore windstopper material and works great at keeping me warm. Typically, when cycling in conditions in the mid 20-mid30's, its the glutes, abdomen, and upper thigh that gets cold. Not in these, looks like Castelli has more robust materials in those areas, so great design there, However, the leg length on these is way too short. I may be an outlier in terms of inseam at 34.5", but these tights are at least 2-3 inches short. Not even long enough to cover my shoe booties, so I have a gap that allows air, and more importantly, water to get in. Overall fit with the XXL is not compressive, barely snug, but I couldn't imagine getting any shorter leg length. Can never understand why these cycling clothing companies can't get the lengths correct on their gear. I mean what is the issue with making the leg length on a pair of winter cycling bibs longer to insure that there is maximum coverage down to the ankle?

First ride was in 25F weather and these kept me warm from the waist down. I could see these comfortable for me down into the 15-20F range. Fit is pretty good if not just a bit short for me but I felt a XXL might get baggy. Wish the bib was cut a little higher so there was some abdominal coverage. Would buy again.

Have ridden several hundred miles in these Material choices and construction are superb. I prefer these for warmth and for flexibility to both of the Gore Bike Wear winter bib tights I've owned. I've ridden them up and down long climbs in temps from 33F to about 54F and remained comfortable, though at 54F I did unzip the ankles and roll the legs into knickers. Now for fit. In slacks I buy 32" waist, 30 or 31" legs. My height is 5' 4 ¾", though before old age disk degeneration I stood a bit over 5' 7 ½". Weight is 136 lbs. In cycling bibs I usually have bought medium, though in some brands small is better. Based on Castelli's size chart my circumference at the hips is perfect for their small bibs. I bought the small. Indeed the volume of the seat and hips is fine, and the shoulder straps are just a bit on the tight side (which is better than too loose, to hold them up). However the legs are not long enough. Leg length is OK when standing, but when seated and pedalling the anterior side of the legs must stretch a lot as the knee flexes. Combined with the thickness and stiffness of the anterior wind resistant fabric I quickly developed bursitis above the knee caps (suprapatellar bursitis). Solution was to have a seamstress insert 2" of soft stretchy Polartec into the seam between the front knee panels and the front thigh panels. Probably I would have been better served with size medium, putting up with some bagginess over the butt.
