Using Bib Tights reduces a layer of clothing for my legs. I used to use inexpensive thin tights under my shorts but it becomes a hassle to use and the seams can be uncomfortable on longer rides. Even though the Entrata is an entry level Castelli Bib Tight it is comfortable to wear and fits me perfectly. The material is stretchy yet provides good support with a nice pad. At 5' 10" 180 lbs. I use Castelli XXL Bibs and Bib Tights and they fit just right. I am a daily rider usually 1.5 hours. On colder mornings I had to balance the layers vs the temperature changes throughout the day. I found that I can tolerate warmer legs than too many layers on my upper body. As a result I have been using the Bib Tights much more than I first thought.
I have been using this bib short just like the previous version, on road and gravel. The legs are long for protection with good compression and the grippers are wide and hold. The pockets are secure and large enough to hold my iPhone and easy to access while riding. The pockets are close to the thigh when empty and easy to stash wrappers while riding. I actually had to look if my phone was on my thigh because it was so comfortable. This short has everything I need for comfort and ride protection. The chamois is very comfortable and the shorts are abrasion resistant.
In Large,these bib knickers fit my 5'7",170lb bod absolutely perfect! They are tight as a second skin. Long enough to go about 6" over/above the calf, of my compression socks. No cold air leaks allowed. Just enough chamois to cushion my sit bones. The chamois could be a bit thicker, but my first 30 mile ride in them yielded terrific comfort. No creeping of the legs or suspenders. They stayed in place until the very end of my ride. At the under $100 price I wish I'd bought a 2nd pair. LG makes great products.
I've long been a big fan of Castelli's top-line bibshorts and tights. The use quality materials that last forever, and, unlike some other major brands I've used, I've never had a problem with stitching coming undone or materials fraying - and I have some Castelli bibs that I've used way longer than intended. The Unlimited Endurance Bibshort is my favorite yet, with more supple materials and very usable pockets which are fantastic for long days out or for quickly accessing a phone or gel. My favorite part is their Progetto chamois.It is thin enough that you never have that diaper-like feel you get with some bulkier chamois, but their blend of densities works great for anything from a short spin to extremely long days out. I recently used these for one of my longest, most strenuous days yet 9 11 hours and over 11,000 feet of climbing. I was sore in a lot of ways, but not in any that had anything to do with these bibs. I have two pair so far, and will ad more, and bought a pair for my wife, and she loves the women's version too. Just remember to size up at least one full size from most other brands, as Castelli run small. Hugely recommended.
