On-trail or off.

If you're looking for a pair of shorts you can wear before, during, and after your casual trail ride without having to bring a change of clothes or risk feeling uncomfortable, Patagonia understands, and that's why it created the Dirt Craft Bike Shorts. Created with a 2-layer design, the outer shorts are cut slimmer than your standard mountain baggies from a stretchy spandex/nylon blend and finished with a water-repellent DWR coating.

An adjustable waistband, articulated knee, and versatile 11.5in inseam all serve to better adapt the shorts to off-the-bike activities. When you're on the bike, the outer layer pairs with a stretchy, moisture-wicking inner liner, complete with a cushy, 3-layer chamois and mesh paneling to keep you comfortable during long days on the trails.

  • Up your trail/all-mountain comfort with this versatile short
  • 11.5in inseam provides coverage without bulk
  • Slim fit is tailored to follow your body movements
  • Spandex/nylon blend fabric is breathable and light
  • Adjustable waistband and articulated knees customize fit

The Patagonia Dirt Craft shorts are awesome! They are true to size and fit great. The length isn't super long and the shorts themselves aren't to baggy. Awesome buy!

Patagonia, please keep making!

  • Familiarity: I've put it through the wringer

I seriously threw all my other cycling shorts and liners away and bought multiple pairs of these. They are amazing. Breathable, comfortable and just all around actually comfortable.
I need Patagonia to invest more into this line because I will continue buying. I really wish they had a winter lineup for us cold weather riders.

Had to buy another pair

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

My dad loves these shorts so much I had to get him another pair. The fit is true, the quality is superb of both the shorts and the chamois, and they look freakin' sweet.

Awesome shorts

Just like everyone else, I LOVE these shorts. The chamois is super comfy and the shorts are a great material.

My favorite part is that you can wear them casually and they don't look ridiculous like a lot of bike shorts do. They are a little longer than a casual short but not too wild.

Long - Not Crazy Long but Long

  • Familiarity: I've used it several times

Patagonia, easily my favorite outdoor brand due to the standards and mission of the company, enters the bike space with a killer MTB short.

I got the green with the yellow zippers and belt, and the main color is subtle like a seabreeze, while the contrast pops vividly. Now at least I know I look the part, amiright?

Personally, not a huge fan of baggy, or super long shorts. While these are baggy and I knew it, I do feel they're marketed towards before-during-after ride. I would not wear these to work, nor would I wear them to a bar or dinner. 11.5 inch inseams, even for this 6 foot dude, are a bit too long. They still scream, "I mountain biked today, I ride, I'm gnar!"

I really want somebody to nail the non-spandex, non-baggy approach to breathable cycling gear that I can wear around town before or after without looking like I'm an advertisement for the sport. If anybody knows a style/brand where I can find that, please gimme a shout!

Giro makes a few "urban style" overshorts (pair with a chamois liner, sold separately): Ride Overshort 2.0- 9", Venture Shorts-- 11", Truant- 14". Numerical sizing (waist) of Giro shorts is pretty accurate. Hope this helps

Thanks Art, I'll look into that for sure!

Awesome Trail Shorts

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium

I'm 5'11" and 178lbs. Typically a 32 x 32 in most jeans. I got the medium's in these and they fit great. They're definitely on the more athletic fitting of bike shorts, but they are super comfy and breath well. Really happy wearing them when trail riding and fit decently with the Leatt Airflex Pro kneepads underneath!

- I love the fit. They're non baggy baggies and fit right above the knee. Athletic fit is what I'd call it.
- The material is stretchy and breathes well. I'd also be pretty happy wearing these hiking and for casual use. I haven't had many diggers with these yet, but the material seems relatively durable. That said, if you're planning on doing bike park laps or free ride stuff, I might consider something a bit more hefty.
- The liner is pretty spot on for being a first venture to the bike apparel realm. Comfy and keeps you happy on the saddle.
- Though I don't really need to tighten the shorts up at all, the build in belt is pretty slick.
- Pocket situation is fine, two normal pockets and one zippered.

- Only issue I've really had with them is stretching my legs out sideways - it feels just a little tight or something. Not a huge issue, only really noticeable when you're standing up to really hammer and then get back up over the saddle.

If you're in the market for high performance trail short that you can wear off the bike and not look like a bike dork, these are the shorts for you! Photo was taken on the Wasatch Crest overlooking the mouth of Big Cottonwood Canyon.

Awesome Trail Shorts

So Comfortable

    Love these shorts, light weight and wicks moisture while I'm riding.

    The Patagonia Dirt Bike Short is incredible. Starting with the chamois. Very soft, very comfortable, very padded. Even better they vent like a champ as well!

    The outer short is stylish, and really light, but able to withstand a beating. I've done quite a bit of field research and these shorts have held up throughout. They're an easy short to wash. Haven't had any issues with DWR treatment, repels water nicely.

    These shorts are great. The overshort is well tailored for the active cyclist. The leg openings are appropriate to not get caught on the seat or the wind. The waist is more fitted so a medium fit's my 32in waist on point. The pad is just ok, but on par with other shorts in this price range, however, the liner short material is very nice for the money.

    Game Changer

    awesome mtn bike shorts with chamois. compared to a lot of the fox and tld stuff these seem to be of higher build quality and the chamois is super comfortable. only used a handful of times but would highly recommend. wear a 32 and bought a 32 and they fit great.

    Wicked comfortable

    • Fit: True to size

    I love my Patagonia Dirt Craft Bike Shorts. They are incredibly comfortable and the various pockets work great.

    The only thing that I'd change is that they're a bit longer than I'd like.

    Best Baggy-Chamois Kit there is!

    The Patagonia Dirt Craft Bike shorts are so awesome. For one, the shorts themselves are so well designed and don’t look like a weird motor cross style. I live in them in the summer time. They are great for hiking, swimming, smoking the magic grass in the park, and of course, killer on the bike. This design has Patagonia’s legendary quality stitching and button along with an adjustable waist. The chamois is something to really write home about. If you have ever used Patagucci’s Capilene underwear, you will already understand what Patagonia is doing with this bike short liner. The waist band is extremely comfortable, the fit is on point and the pad itself is thick and cushy. Five stars for Patagonia getting into the bike space!!!

    Nailed it

    Patagonia definitely nailed their attempt at making great biking shorts. I wanted a pair that wasn't too long like most biking shorts, so I purchased these. I am 5'11" and they fit just above the knee. The fabric is comfortable and breathable. It fits amazing and works great for mountain biking. The liner that comes with it is also great. It is tight and makes the longer rides more comfortable sitting on your seat. Would definitely recommend these for mountain bikers looking for a good pair of shorts.

    So Patagonia finally got it right. A comfortable, basic looking bike short that performs. They also managed to create one of the best shammy's i have used to date. So far the best shorts for longer days in the saddle. The material is really durable for the amount of brethability which is another difficult part of designing a bike short. Finally sizing. Now Patagonia is a little wild on sizing but i would say they are true. I am 6 foot 185 pounds in a 34 waist . I am a huge biker and love helping people build clothing kits, bikes, or help in any way to keep you rolling. If anyone has questions feel free to give me a call or shoot me an email.

    These Rock

    I wore these all last season. It felt different switching from a road bib but once i got used to that it was way easier to move about on the bike and they look pretty good for food/beer after your ride

    I've taken a few tumbles and they still come out of the wash looking like new.

    There's a big difference between the size of the liner and the short. Once you have them on you dont notice either any more.

    I had all but given up on baggies. Typically what happens is I get a new set of baggies and after one ride throw the liner away because it is total junk. While I am still left with a reasonably nice pair of shorts they are not riding shorts. I waited a while to write this to make sure I really gave these a good shake. The liner is amazing. As comfortable as my best bibs. I even wore these on few long trainer sessions to really check them out. I figured the trainer is the best test since I tend to not stand and if there were any trouble spots they would show here. They never did. With the current run of warm weather here in the Wasatch i have also taken them on a number of road (one over 3 hours) and dirt rides. Again no complaints as to the way they ride. Super comfy the whole way.

    A few little things. The front pockets are comically shallow. My phone sticks out and there is no way I would carry anything in them while riding, or even just walking around for that matter. The side zipper pocket is really nice though. Next, and this is more a comment about baggies in general. They are pretty hot. It is early spring here so it is not a problem but I don't think I will be doing much riding with them come summer. I guess if I rode charlifts at resorts they would be fine for that. Most of my riding is of the long XC type so I suppose I am not really the target buyer for these anyway. That said these are really nicely made and they are super comfortable.

    Patagonia MTB shorts.

      The only "bad" thing or issue I can say about Patagonia's first foray into MTB shorts is that they made to few and sold out before the season even started! I purchase both colors and they are my go to shorts everyday. I have a lot of expensive riding shorts, brands like Kitsbow, TLD, Gore, Club Ride etc. and none of them are as comfortable as the Pats. The only rub and hopefully next years shorts this will be corrected is that they need to make the two front hand pockets deeper, besides that, my go to pieces for the 2016 summer!
