Find my size
Cut no corners, take no shortcuts—the Men's Summit PRO Shell Shorts are our premier mountain bike shorts, purpose-built for riders who demand top-tier performance and technical precision. These men's MTB shorts are constructed from a lightweight yet durable 4-way stretch recycled nylon fabric with PI Dry® C0 technology—a PFAS-free durable water repellent that sheds moisture and trail grit without compromising sustainability.
The ride-tuned fit starts with a wide, low-profile waistband that evenly distributes pressure and stays highly breathable through big efforts. A micro-adjust ratchet waist closure delivers a secure, customizable fit for distraction-free riding, while bonded leg openings eliminate bulky seams for smooth, unrestricted pedaling. Perforated inner thigh panels enhance airflow on hot climbs, and two zippered Trail Access pockets keep ride fuel and tools close without interfering with your motion.
With a pad-friendly cut and no built-in chamois, the Summit PRO Shell Shorts are designed to pair with your favorite liner for a system-level trail kit you can count on every mile.
Match with a PRO Bib Liner Short and Summit PRO Jersey for a complete, peak-performance trail kit.

Great! Sizing is a bit larger then expected
"I’ve worn Pearl Izumi shorts for years and usually size down to a 34, even though their chart says I should be a 36. With the Summit PRO, the sizing is way off, the 34 was huge and would literally fall off while riding. I swapped them for a 32, and even those are borderline too big. For context, I have a 41" waist, so the idea of needing a size 30 is pretty wild. These shorts run much larger than other Pearl Izumi models, so keep that in mind when choosing your size."
Nice short
"Very well made short. Very light but seems tough. Larger than usual. It is a good thing that I ordered a smaller size."
Great shorts
"Good"
Like everyone else says, the waist is large.
"There’s elastic across the entirety of the back, which causes sag. This is impactful when riding especially if you are up and down on the saddle…like with a dropper post. They also run a little long. Past my knee, and I normally wear a 32x32. I took mine to a local alterations shop, and they put a new cinched seem in the back elastic for $16. Easier than a return."
Run large
"Great shorts . . . that said they run larger than advertised and they still have the stupid backwards pockets which I hate"
Size down
"Quality looks good, but the sizing is way off. I wear a large or a 34 in everything but I’m having to size down due to the elastic in the rear."
I am giving these shorts
"I am giving these shorts a poor rating. I purchased 34 size and found them slipping down while riding and bought 32 as thought would be better. Not the case. Still sliding at the back when buckle fully closed. No rubber stoppers on waistband and waistband elastic is too loose. Now have 2 pairs of same shorts that I have to try to sell. Would like to return them for size 30 but used now. Or install rubber on to waistband? Nice fabric but poor waistband design. Not happy, especially for the price and money I have spent. Murray A."
Solid shorts.
"I bought these a size smaller because my Summit Shell shorts were right at the margin of being slightly big. As previous reviewers noted these fit a little large and to size down. They are very comfortable, but even at the smaller size are slightly big. Not falling off your rear big, but just a little loose. I have worn them on a 160 mile ride and they were comfortable I also wore the transfer cargo liner shorts."
Very Different Fit From Summit Shell Shorts
"The back of these shorts is an elastic section. As a result they are much stretchier than the Summit Shell Shorts and wear like an entire size bigger. Disappointed with the fit inconsistency. Material is great, and the length is nice as well. I just wish the sizing was consistent across different products."
Pretty close to perfect
"Great material, great fit. pocket design and shape is good. Would add an ajustable waist band."
