Ashlu Merino Sock

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.

Women's Foundation Bike Brief - Sale | Bike Underwear - 7mesh

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

These are great. I did measure to make sure I got the correct size. Working the way I want - padding but also not bulky

Exactly what I wanted!

These are really comfy, I bought a size L to be safe (got a biker booty!), but I found them quite tight the first few rides. They have now relaxed a bit, but definitely go a size up from your usual sizing (I usually wear a M in 7mesh)

Love them - but size up!

Really confortable and when you travel often like me they don't take much place in a suitcase for the confort they bring for MTB

In love

These are my favourite bike short liners. Just enough padding, but doesn't feel bulky.

Love em!

The brief fits me perfectly and is very comfortable. I like the flexibility of being able to wear briefs for a quick ride with my street gear or double up with my regular riding shorts for extra comfort on longer rides. Have a brief is nice as it is cooler in the summertime than wearing a full padded short. It is also easy to clean and is a great addition to my cycling attire.

Padded Brief Comfort

This style seemed like a nice idea, but it doesn’t fit me at all. I’m at the upper end of the medium size range for both waist and hips, and for basic fit the medium feels like it’s either the right size or just slightly small. Problem is the pad lands an inch or two back from my sit bones, making it useless. The leg openings also pinch in the front. I’m not sure what variation of body shape or fit is allowing this to work for some of the other reviewers…

Pad is too far back, leg openings pinch

I've bought two pairs of these and I really like them — they feel really light and airy compared to my usual biking chamois. I'm right in the middle of the size range for an XS, and they fit just right, although the waist band is snug. I could see if you're in between sizes you'd likely want to size up so that the waist band isn't too tight.

I'm a fan

Ibdid not like the brief. The padding felt as if a were wearing a maxi pad. The cut of the brief is uncomfortable as it falls in the crease of the leg. Walking with the brief after the ride also felt unpleasant. I have a boxer as well which fits much better. I wouls still recomend a sligtly longer leg on the boxer

Uncomfortable
