The Boxer Brief is perfect for rides when you don’t want to commit to full-on padded undershorts. They’re light, quick-drying, and airy, with enough coverage to reassure without restricting movement. A low profile chamois provides plenty of comfort and support and keeps out of the way when you’re off the bike.

Women's Foundation Boxer Brief - Women's Bike Boxer Underwear

Products that blend performance fabrics with highly articulated patterns to create a close-fit that feels like an extension of your body. Skin Fit apparel improves aerodynamics, moisture management and thermal efficiency.

Skin Fit

I had a couple of the foundation briefs already, but the boxer brief is definitely my favourite. I sized up to a medium (I’m a UK 8-10) and find them perfect padding for short lunchbreak rides. Highly recommend.

My favourite for the quick lunchtime blast

Not just great for short rides, I can highly recommend these boxers (and the briefs) for longer rides too! Ok I'll admit, I didn't actually race the 7 stages of BC Bike Race, but I worked on and rode the course all day every day. Imagine being in chamois from 7:00am-5pm. It gets hot! After 8 days, including pre-riding, I still came out feeling fresh-ish and bumpy-free! (With a plug to the NinetyK Nirvana saddle.. as that was the killer combination I had been after for so many years).

7-day stage race in these!

I haven't worn a chamios for years- simply because they're too bulky, to moist :|, and just darn awful so I'd just suffer on those long days or multidays. These are amazing. Like other reviews, its enough to take the edge off and hardly noticeable after if you're out n about. Size wise I was right between small and medium, with advice ordered the small (I also wear small shorts). They are snug but stay in place and don't dig in anywhere when riding. I'm going to order a 2nd pair.

Perfect

Everyone is different but after getting these I have ditched the chamois for all but road and multi day gravel packing ... and even then, on trips where I want to pack as minimally as possible I've chosen these over my bibs. The padding is perfect for keeping my sit bones happy, and the boxers are slim enough that I have no problem hanging out in them after riding for apres or running errands post ride.

Goodbye Chamois!

Perfect layer for short rides or skills sessions where I am out of the saddle or off the bike a lot. The fit is really nice and comfortable. You get a pad for when on the bike but you really don’t feel the pad when you are walking or standing around. Perfecto.

Great for short rides

It took me a hot minute to get used to the Brief style of shorts underneath my baggies but I quickly got over that and now want to get a few more pairs. The fit is on point and comfy. I haven't used this for any longer rides however great for coaching sessions, shuttling/bike park days and easy peasy days on the bike. I am a short human with a huskier hourglass build with powerful quads & glutes and these didn't cause too much issue. 62"/158 cm ~166lbs/75 kg 32" waist, 44"hip/butt usually a medium/large/Size 10 in regular clothes, sized up to an XL for these.

Magic Shorts!

I was so excited to see this new product! I own the Foundation Brief- I have been wearing them to commute for the past year. 
The boxer brief is even better! I love have the extra length on the thigh area.
The chamois is just the right weight and size to keep you comfortable on short rides.
This product is just really comfortable. I like to be able to ride to work in a dress- so you get the comfort of wearing cycling shorts, without looking like you are out to train/exercise.
I am 5'7', 130 lbs and the Medium fits perfectly.

Great Base Layer

These are so great for mtb rides under 1.5 hours. Very breathable and not bulky. Awesome product.

Great for short rides/skills sessions

Perfect for layering or a more laidback vibe, Relaxed Fit products combine articulated patterns with an eased shape that works on or off the bike.

Relaxed Fit

Designed to sit slightly off the body, Trim Fit products provide some room for light layering and feature mechanical (fabric) stretch or elastane, combined with articulated patterns.
