Our Bike Short runs true to size, but is extremely fit flexible, meaning you may fit comfortably in more than one size. If you’re between sizes, prioritize your hip measurement for a squat-proof fit.

How to Measure

Bust:
Measure around the fullest part of your chest, while keeping your tape measure parallel to the floor

Waist:
Measure around the narrowest part of your midsection, while keeping your tape measure parallel to the floor. This is typically where your body creases when you bend side to side, and usually lines up with your elbow crease. Your belly button may be lower than your waist.

Hip:
Measure around the fullest part of your butt, while keeping your tape measure parallel to the floor.
This is much lower than the top of your underwear, and is typically just above your crotch.

Why we made this

The need for activewear doesn't end at the water, what if you want to paddle board in peace without a wardrobe malfunction?

We chose activewear seams and specialty construction to create a super soft waistband, and a leg trim that wont roll or ride up during your workout. We performed rigorous testing so you don't have to worry about chlorine, seawater and UV rays wreaking havoc in the water. With our lightweight fabric, they're also perfect to wear under skirts and dresses to prevent chafing, or a Marilyn moment. We also added side pockets in just the right size to stash cash, cards, lipgloss or a phone -just remember to remove before you dive in!

We sweat the small stuff

With purpose-built products, every detail is designed to perform. So go ahead and pack light- we did the overthinking for you.

Flatlock Seams

Low-profile seams that stretch with you and reduce bulk.

Reflective Logo

Stay-Put Leg Band

Stash Pockets

Side pockets to keep your belongings secure.

Functional Fabric Innovation

We engineered our fabric from the ground up, for unmatched performance, durability, & all-day comfort.

Premium Polyamide 66

Superior strength, durability and abrasion resistance to withstand wear after wear without wearing out.

Interlock Structure

Half of our polyamide 66 is made from post-industrial recycled materials, and nearly all of our polyester is made from post-consumer recycled sources.

Our fit is generally true to size. We recommend checking our Size Guide, which contains measurements and notes to help you find your perfect fit. However, if you’re between sizes, we recommend sizing up. Because of the lightweight, high-stretch nature of the fabric, you may fit comfortably in more than one size. Our Product Fit Guide is also here to help you understand what the perfect fit should look and feel like, but please don’t hesitate to contact us if you need help figuring out the best size for you!

Yes! All of our products are rigorously tested to ensure they can withstand normal exposure to chlorine, seawater, sweat and UV rays. However, to prolong the lifespan of your garment, it’s recommended to rinse thoroughly with fresh water after a swim or sweat.

We categorize workouts by impact, meaning the literal force of impact (jumping) a type of workout typically includes. This influences how much compression and support the wearer may require to perform their best. Here are some examples:

Light impact: Yoga, Barre, stretching, walking, swimming.

Medium Impact: Pilates, spin, strength training, hiking, cycling, light cardio.

High Impact: Running, mountain biking, HIIT workouts, boxing, CrossFit.

Machine wash cool, gentle cycle. Tumble dry low. Non-chlorine bleach if needed. Do not iron.

Hand washing and air drying are also encouraged.

For best results, rinse clean after exposure to chlorine, sweat, salt water or sunscreen, and allow to dry thoroughly before storage.

The quick-drying fabric performs well in various conditions. While drying times can vary significantly with high humidity, it should dry much faster than traditional cotton underwear and most swimwear.

Yes! If fit correctly, our shorts should maintain opacity at all times. However, due to the lightweight, high-stretch nature of the fabric, you may fit comfortably in more than one size. We recommend prioritizing your low hip measurement on our size chart, sizing up if you’re between sizes, and choosing a neutral color of underwear. Please don’t hesitate to contact us if you need help finding your perfect fit!

No, cotton is highly absorptive, which makes it a great choice for underwear, but a poor choice for quick-drying swimwear. Our gusset fabric (aka, crotch lining) feels like cotton, but is made from a recycled polyester/spandex blend, with perforation for high breathability.

If you are prone to imbalances from synthetic underwear, these might not be the right choice for daily wear, but are a much more breathable option than traditional swimwear!

We offer returns on unworn items within 30 days of delivery. Please see our full Returns & Exchanges page for details and instructions.
