At first glance, bike shorts and compression shorts might look very similar. Both are form-fitting, made of some material like spandex, and obviously designed for athletes. After looking further, however, the two types of shorts have some fundamental differences that cannot be overlooked. Since we have seen some people trying to use compression shorts as cycling shorts, we thought this article was important. True compression shorts are not to be confused with cycling shorts or triathlon shorts. They are their own animal, and for good reason.
Before we go any further, it is important to note that we are comparing the outerwear-style compression shorts made by makers like Zoot and Pearl Izumi to bike shorts. It is obvious to most people that the less-expensive shorts like UA compression shorts and others are not intended for outerwear or cycling.
What is the Difference?
There are a couple fundamental differences between cycling and compression shorts. First and foremost, bike shorts have padding. This padding is incredibly important as it is what separates you from your bike saddle on a long ride. These pads are usually made of a chamois-like material, so very soft, and can be of various thicknesses. They are stitched in to the short in a very seamless manner so the part of your body that had contact with the pad does not chafe.
The compression shorts normally are tighter, and focus much more on consistent compression throughout the quad, hamstring, and glutes. Because of this, they are specifically intended for athletic performance and recovery, and offer the benefits of compression than you get in high-end compression tights as well. Bike shorts, while form-fitting, do not offer this type of technology. Their main purpose is to be comfortable and effective on long bike rides, not to be a compression short.
As for construction, we usually find that the bike shorts are made of a higher proportion of poly or poly blend, while compression shorts usually have a little more spandex. This helps the compression shorts keep a very firm fit on the athlete’s leg at all times. At the same time, the cycling shorts often have more prominent leg grippers, as there needs to be something that keeps the short from riding up the thigh on a long or intense bike ride. These leg grippers more often than not are made of some type of elastic, and are fitted with an outer covering that makes them easier against the skin.
What To Look for in a pair of Compression Shorts
When buying compression shorts, the name of the game is to get — you guessed it — compression. Most people who want compression shorts are interested in at least some aspect of the technology built in to the shorts that helps blood flow and accelerates recovery. A good compression short will be snug but not so tight it is uncomfortable, and the seems need to be perfect. If a seem is too pronounced or even a little rough, the compression qualities of the short will go unnoticed due to the discomfort of wearing them. Any points of contact with the skin should be snug but also smooth.
Our favorite compression shorts typically come from the makers Zoot, Pearl Izumi, 2Xu, CW-X, and some others. Those makers are in tune with the demands of serious athletes, and we find their compression shorts to be top-notch.
What to Look for in a pair of Bike Shorts
Bike shorts are a different animal than compression shorts when it comes to buying them. Cycling shorts need to be comfortable on a bike ride, which is different than comfort from a compression standpoint. When looking at bike shorts, we like to really focus in on
First, the seat pad is obviously crucial to your comfort, especially if you do rides of more than an hour or 15 miles. The seat pad should be something that doesn’t get in the way of your pedal stroke, feels very uniform on the saddle, and is substantial enough to keep you comfortable even on a long ride or during a grueling spin class. The cushion on your bike seat (or lack thereof) may also have a bearing on how much cushion you look for in your seat pad.
Second, we look at the thigh grips. These elastic pieces need to be strong enough to keep the shorts from riding, but not so strong that you have an imprint for hours after each ride. Worst is a thigh grip that cuts into your skip and causes chafing. One of the first places we notice high-end shorts diverging from the cheapo models is in the leg grips.
Finally, we like to be sure the shorts provide a general level of support without being too tight. As such, we recommend that once you find a pair of bike shorts that works for you, you simply continue to order new ones online – same brand and size – and you will be happy with a consistent feel and fit for years.
