This vs. That features a comparative analysis of two trending products, offering a technical review of both items and cutting through internet discourse with authority. For this installment, we compared Free People’s newly popular Carpe Diem shorts against the Good Karma Running Shorts to determine which are most comfortable for a run. Read the full review below.

I’ve been running in compression shorts or bike shorts — whatever you prefer to call them — for about 12 years. I always presumed that the formfitting material applying pressure to my lower body stabilized my muscles and offered me added support. So, I never really thought about testing a different silhouette until I caught wind of Free People Movement’s newly-launched Carpe Diem style ($40). Released the second week of February 2024, over 75 percent of units were sold within three weeks, according to a brand rep. In addition, the 4.8-star rating speaks volumes, with plenty of shoppers praising the comfortable, flowy fit and begging for more colorways. My first thought amid the never-ending heat wave in New York? “Hmm, I wonder if the loose leg would give way to better air flow during my runs.” I had to find out.

Since I’d also never tried Free People Movement’s running shorts specifically, I chose a bestseller of equal value: The Good Karma ($40). These are lightweight and breathable like most of the compression shorts I own, but with the bonus of SPF 30 UV protection. The FP Good Karma collection is comprised of non-bulky basics that are described as having a “barely there” feel, which sounded right up my alley when it comes to workout clothes. I chose the Sour Citrus color, finishing with the Can’t Lose Bra ($30) in Limeaid, which made for what I’d describe as my typical running outfit.

Once I also got my hands on the buzzy Carpe Diem Shorts in black and white, I went for a few runs to compare how I felt in both styles. Ahead, read my full review.

Differences Between the Free People Carpe Diem Shorts and Good Karma Running Shorts

There are many differences between the Carpe Diem Shorts and Good Karma Running Shorts, starting with how they feel. While they both have a ribbed, high-rise waistband, the Carpe Diem’s knit material is way more relaxed in comparison to the Good Karma’s band, which is described as designed to “hold you in.” That being said, the compression was less than I’m used to and ultra-stretchy on the Good Karma. (You’ll notice that some of the models in the styling pictures easily fold them over for more of a low-rise hot pants look.)

Of course, it’s like day and night describing the difference in tightness around the thigh. Whereas the Carpe Diem is more-than-roomy, with a curved hemline that blows in the wind as you run, there’s compressive ribbing on the very bottom of the Good Karma that cinches the upper thigh. According to the product description, this is so that the shorts don’t ride up while you work out (a thoughtful bonus), but I didn’t love the feeling of the tighter strip so snug around my thigh. In fact, during my run I honestly felt like the crotch area was a bit baggy in comparison. This lack of consistent compression gave the Carpe Diem a leg up in the competition. (See what I did there?)

What’s Worth Noting About the Free People Carpe Diem Shorts and Good Karma Running Shorts

The breezy feel of the Carpe Diem Shorts is definitely what stands out to me, especially in humid weather. While I didn’t experience chafing personally, it’s important to remember that the fabric moves with the wind and your own motion, so if you don’t love your upper thighs becoming exposed on a run, these may not be for you. But you need not worry about a full reveal — the Carpe Diem comes with built-in briefs for added coverage, and I found them to be quite comfortable. Also, my white pair isn’t sheer, so you don’t have to attempt to hide your panty lines. If you are concerned about a look that borders on too leggy, size up, as many reviewers suggest this helps with length.

Meanwhile, many shoppers found the Good Karma Running Shorts to be unflattering, particularly where I took issue with them — at the thigh compression band, where some people also reported the fabric rolling. Some folks also wrote that the material is flimsy and even see-through, but this may be due to multiple wears and washes as this wasn’t an issue for me.

Who Are the Free People Carpe Diem Shorts and Good Karma Running Shorts Best For?

The Free People Carpe Diem Shorts are for those who like to run in non-restrictive shorts that have built-in underwear and roomy legs for added air flow. They are short, so make sure the 3-inch inseam is long enough for you. The Good Karma Running Shorts, measuring a 2.75-inch inseam and 9.5-inch rise, are for those who like versatile bike shorts that you can wear with the waistband extended or folded over. If you’re going for the Good Karma, you must be comfortable with a tighter fit, although the compression is medium and on the stretchier side.
