That is a personal choice :). Castelli do make great products - undoubtedly.
However, we are a different company. Our niche is - Long Distance BibShorts.
When you come to us, we want you to have absolute confidence that what we give to you is a BibShort that is designed specifically for your long ride. No compromise has been made in achieving this end in the design process.
For example, we don't print on our lycra because its a nylon based fabric that's softer and more luxurious than a printable polyester based version. Comfort reigns king over graphics and that's a choice we made happily to achieve the end goal - long distance comfort.
The chamois isn't one that's used by many other brands. We searched for a non mainstream manufacturer. The chamois is manufactured using a Thermic Moulding process - no one else makes a chamois this way and what you get is a plush, breathable chamois that lasts and doesn't flatten out after long hours.
