Made with buttery-soft, ultra-breathable four-way stretch and a wide, low-bulk waistband that stays put—so you can focus on the trail, not your gear. A 12.5” inseam gives added coverage and plays nice with kneepads, making it ideal for long pedals, loose descents, and unpredictable days. Dialed details include: two front drop-in pockets, two drop-in pockets in back, and a zippered thigh pocket for low-profile storage. Tailored like a vintage trouser, with a playful pop of color in back.

This short is recyclable which is harder than it might seem. Instead of using spandex for stretch we used a special polyester stretch yarn for performance and fast dry times, with the bonus that it’s easy to recycle. If your Sun Dog Pant reaches the end of its very long, happy life, send it back to us for recycling or repairs, supporting a circular economy.

Full Coverage. Zero Fuss.
Kneepad compatible- for when your curiosity lifts off.
"These shorts fit over kneepads without looking too baggy and oversized, which is a big win. But the real kicker is the soft high-rise waistband. Doesn’t pull or gap when seated on a bike and allows for a lot of movement." - Brita, ★★★★★
"I can't say enough good things about these shorts; the fit and the comfort are there, and I feel good knowing that the people who made them were paid fair wages and worked in good conditions." - NSMB
These shorts are absolute rockstars. The yoga style waistband feels so nice around my belly when I'm riding, stretchy and comfy around my thighs, and so many pockets to choose from! Finally some mtb shorts with a nicely placed side zipper pocket, back pockets, and front pockets. I usually wear a large or XL in most shorts and these in a 12 fit really well.
Perfect combo of function and style. Loving the longer inseam for a good interface with my knee pads. True to size in the waist but slightly slimmer than expected on the thigh. Great stretch and pockets!
Big fan of the comfortable fit. I'm 140, size 8, and these are true to size for me. I'm never going back to button pants again, lol.
These are perfect mountain bike shorts, especially for a plus size rider. The fabric breaths and moves with my body. I’m not worried about fit or feel, it’s just magic!

Truly my favorite shorts for mtb - perfect length, great pockets, comfy waistband, and the color is so so so so pretty, especially in person. Can’t wait for more colors of these one day!
The bitterroot shorts are a great pair of shorts- I mountain bike, but also canoe and I wanted a pair of shorts that would do both. These are perfect- they are stretchy and comfortable- both paddling and biking; they have pockets and they dry quickly (essential for canoe trips).

Love the fit of the bitterroot short. 12 in leg is right on. Fabric is cooling Nice to have back pockets but practically speaking having at least one of those be secure would be great for riding. That aside - I really like these shorts!!
So so happy to find a new cute bike short that has the elastic waist band and fits well. Every time I ride I only want to wear these shorts. I ordered a size 8 and they felt TTS. I’m 5’7, 145 lbs. I’ll be trying the pants next!
Comfortable and stretchy material. Love the pull on waist and overall fit. Purchased the color brown in size 2. True to size but size up if you want a looser fit. Side zippered pocket is deep and roomy enough to carry an iPhone and a few gel packets. The brown color with pink back pocket is stunning. The Bitterroot Bloom are my new favorite. Looking forward to more colors.
These are my new favorite shorts, great length for mountain biking through all the chunky PNW trails! They fit like a dream with the stretchy high waisted band and the pocket placement is top tier! These are confidence inspiring and breathable, my personal go-tos on hot days! I personally wouldn’t change anything about these! I can’t wait for more colors! 🤩
A pair of bike shorts that have room for my big 🍑 & thighs without the waist gap- a dream! I tried on everything at my local shop to no avail. Super comfy! Super cute! Loads of compliments. So great I can easily hop off the bike, drop the chamois and roll right into bringing my kids to all their summer activities all day. I was worried about the length, I don’t like feeling restricted pedaling. I’m normally a Ripton gal for mobility, but took a chance on these. So so glad I did.
These shorts fit over kneepads without looking too baggy and oversized, which is a big win. But the real kicker is the soft high-rise waistband. It’s flattering and soooo comfy. Doesn’t pull or gap when seated on a bike and allows for a lot of movement. I haven’t worn any other shorts since getting these and I’m not sure if I can go back now! Love the colorways, too.
Love these! The new longer inseam is great and interacts well with my knee pads (I don't like a gaper gap!). The waistband is heavenly! Period bloat or hotdog bloat -- don't matter, these are staying comfy the whole ride.
