The perfect athletic underwear doesn't ex.................. <insert stunned silence with a gaping jaw>

Introducing Pyka Pants... the world's first hybrid undershorts for anybody who squats when they pee. Pyka pants started as an idea in 2008... and have been in the design process since 2018. 

Pyka Pants features an original print by Kula artist and creative director Amanda McIntyre. This crevasse print was meant to capture the feeling and movement of goacial ice.

We have put a lot of love into the design of our Pyka Pants - and they are all made right here in the USA. We hope you love them as much as we do, and we can't wait to see them on your adventures. 

How can you use Pyka Pants?

They are meant to be worn under normal hiking pants as your underwear... but they also work as standalone shorts for any athletic activity (or even just lounging around!). You can use them as a swimsuit for alpine lake dives... and they also work *perfectly* under a hiking dress or skirt. 


- single layer wicking fabric on 'body' of shorts (i.e. black fabric) is quick drying and moisture wicking. These will not feel like a standard, thick spandex yoga short - so they are perfect to wear as your underwear and will fit easily under your hiking pants.

- smooth, high waistband prevents chafing from hiking pants or backpack

- pocket in waistband at back is the perfect size to stash keys, a bar or even a cell phone

- made in USA

- can be used as shorts or underwear

- gusseted crotch for ease of movement

- size XS weighs approx 2.64 oz

Pyka Inseam is 6” size XS-L, 6 1/8” XL, 6 3/8” 2XL, 6 ½” 3 XL, 6 ¾” 4 XL & 7” 5XL. This is measured from the center of the crotch panel.

Materials: Single layer wicking fabric (body of shorts) is 100% polyester. Waistband and side stripe are 84% micro poly and 16% Spandex - Ultra-Light Performance Body Flex.

Care: Machine Wash Cold, Gentle Cycle, Remove Promptly. Line or Tumble Dry.

Sizing info below - please take measurements and use our size chart when determining the proper sizing for your Pyka Pants. 

A note on sizing: After testing, it is our understanding that the shorts run true to size. If you are between sizes, we recommend using the size that fits your low hip and thigh measurement most accurately.  So, if your waist is a 34 but your hip is a 43 - we would recommend sizing up to the large.

Love the fit!

I’m a big fan of the pyka pants. I got them for backpacking this summer. I’ve used them a few time snowshoeing and honestly lounging around the house and they are so comfortable! They are compatible with gnara hiking pants too! They hug all the right spots and I’m not constantly adjusting them (as I usually have to do with other boxer like underwear). I highly recommend! Will definitely be getting more this summer!


Awesome pants!

Love my Pyka pants so much. I've worn them standalone and as an underlayer. Only thing I would note is they ride a little low in the back, so if you have a bigger booty maybe order a size up!

Pyka pants awesom comfort on horseback

I believe they are great in winter for chilly days under my jeans horse back riding . No itchy seems maybe a little bit on the lower side on my bumm where the two fabric colors meet but for the most part awesome comfort the rest of the seems! Sometime regular undies have seems in sensative location on the front of the crotch that can be very annoying! Not these however the polyester is too warm for summer i dont do well on warm days with poly!
