Have a question? We'd love to hear about your next adventure.

Model is: Height 5’7”, Hip 36.5" and wears a small.


Made with a free-feeling low profile chamois, Foundation invites refreshing airflow right where it’s needed most, and dries fast under intense efforts in hot conditions. Designed for short rides, gravel grinds, park days and anything that ends with an extended après, the Foundation Brief supports with “just enough” cushion, providing comfort for those who don’t want to commit to full padding and coverage. A minimalist waistband keeps the brief in place but doesn’t dig in when you’re digging deep.



  • Body: 62% nylon, 18% polyester, 20% elastane
  • Lining: 100% polyester


  • Ergonomic padded brief
  • Lightweight protection
  • Minimalist waistband

  1. Love Riding

    Lightweight and comfortable

    These would be great for short rides to run errands, or for the bike park, but I personally would find the padding too thin for longer rides, especially if there is a lot of sitting involved. I've used them only for a couple of 30 minute indoor trainer rides but for anything longer, I would ...

    Great product!

    I wanted something that could go under some capris I had; mostly for indoor spinning. Have used them a few times and works really well! Pretty seamless also which is great. Thiner padding, comfortable. Canadian company!!

    These Briefs are perfect

    So comfortable and lightweight. They are great even on longer 2+ hour rides.

    Lightweight and breathable

    The perfect amount of padding when you need a little but don't want to feel like you're wearing a diaper. Stays in place, dries quick, washes well. I wish there were more garments with thin chamois like this - if the WK3/WK2 had a lightweight option like this, I'd buy multiples!

    These are perfect!

    These are my first bicycles "pants" and I'm excited :) They are thin but functional, nice and my body like them. I was afraid they wouldn't be for long trip, but they are very perfect. Thank you for other great product.

    LOVE these for rides around an hour. Comfortable and lightweight - easy to run errands in afterwards. I'm a size 6 and the M is perfect.

    These are great!

    These are exactly what I have been looking for to wear while riding on the trainer indoors, for shorter/hotter rides, or on bike park days. I would agree with the other reviewer. As a fuller figured gal, I’d appreciate a bit more coverage. Perhaps a higher rise, or boy short? That said, these are ...

    Does the job! Like, better than I ever expected.

    Not flattering for the full bodied gal; wish they made a boy cut rather than a brief. However, once I put my mtb baggies over top I forgot that I looked like a marshmallow because these felt so good! Went for a quick spin - about 40min 9km singletrack- mix of sustained climbing and tech dh. And ...
