1. Underwear: Cycling bibs and shorts are meant to be worn without underwear.
2. Budget: Cycling bibs and short can range from $20 - $300, so try to set a budget before you shop based on how you intend to ride. The higher the price, the more technical the fabrics and better the chamois.
3. Tight or Baggy: Tight-fitting shorts are best if you are primarily cycling on a road bike and/or for long distances. They offer the most comfort and aerodynamic fit. If you spend time off the bike, touring or commuting by bicycle, need pockets, or are more concerned with the look of the shorts than your speed on the bike, then "baggy" Mountain Bike Shorts with a liner may be your best choice.
4. Padding: Padding ranges from thick to thin, with triathlete shorts having the thinnest pad so athletes can swim, bike, and run in the same shorts. Spending a few extra bucks for a better chamois is never a waste of money, since the difference in quality, durability, and comfort may increase exponentially with each dollar spent. But, always read the customer reviews to make sure your money is well spent before you make an upgrade commitment. Properly designed cycling shorts will always have chamois that are designed specifically for men and women, so you should never buy a unisex cycling short. You'll be sorry you did.

5. Panel Construction: Less expensive shorts usually have fewer panels of fabric, while the more technically designed and form-fitting bike shorts can have up to eight panels. Just being aware of the construction of the short will help you to have an expectation of the comfort and performance.
6. Waist Band or Bib: Bib shorts that offer shoulder straps, rather than an elastic waist band, are the choice of all professional and elite cyclists. They decrease binding and discomfort around the midsection and will never feel as if they are moving or shifting (sliding down) while you are riding. While some people prefer bib shorts, others choose regular shorts. It's completely up to the individual and their preference. Those that choose traditional cycling shorts may want to try them with a yoga-style waistband, which are designed to be cooler and less binding. Read more on why cyclists choose bib shorts.
