Our redesigned Femme 400-Mile short will provide ultimate comfort in the saddle. We increased the pad thickness from 6mm to 14mm and kept all the same great features you loved in the prior model. 

Sizing: Please refer to the size chart button above for sizing guidance. 
Fit Type: Form-Fitted
Fit Note: Please do not assume your size is the same as previous years, please use our size chart and if in doubt, email us at: Bike shorts are meant to fit tight, next-to-skin. This is to eliminate potential chafing. If you’re not comfortable with this type of fit and or are between sizes, we recommend sizing up. Garment will fit the most snug the first time you put it on, it will relax slightly once wet. 

New Features:

  • Updated Femme 400-Mile Pad is now 14mm in thickness to provide supple comfort while in the saddle. Pad is still antimicrobial, moisture-wicking and quick drying. It conforms to your body with 4-way stretch and seams are strategically placed away from contact points to reduce the potential of chafing. 
  •  Wideband elastic wraps around the backside to keep the short up and soft non-elasticized fabric is placed in the front for complete comfort while in the riding position = 2/3 comfort waistband eliminates pressure on the GI
    • Please see image to the left - the elastic has been extended an inch towards the center so it does not hit the hip bone. We added a drawcord to allow adjustability, but if you prefer the short without it's easily removable. Note - If you like the drawcord we recommend knotting it prior to washing.

400 mile shorts, a comparison to previous versions

My first pair of 400 mile shorts were worn until the inner thigh seam rubbed through. They had lightly ribbed fabric and a thin elastic waist. And I liked them. My second pair of 400 mile shorts just never fit as well as the first - they had been redesigned - the fabric was different, the waist was different. They tended to roll down in the front waistband. I just wasn't as big of a fan of the 2nd pair I bought. But I kept wearing them, as they were still my most comfortable shorts to race in. Now the 3rd pair, redesigned again. I can now honestly say the changes are great. At first I thought the pad, now thicker, was going to be an issue. It felt too wide and baggy. I felt like I was wearing a baggy diaper. I was worried I would chafe while running. I wore them on 3 training rides and I have to admit, the waist is better than both the previous models, and the extra padding really did feel better. Still I had my concerns with how they would work on the run. I can tell you, I finally raced in them, and these shorts were absolutely fine. I didn't notice that pad at all. The waist is high enough I don't get that horrible muffin top that so many other tri shorts give. I wear these for training & Adventure Racing. Triathlon shorts are the shorts of choice for adventure racing, however the pockets on most tri shorts are just too small to stash items in. These shorts have 3 perfectly sized pockets. Large enough pockets to hold extra food, compass, punch card, etc. I did size up in these shorts based on the size chart and I think that was a good choice.

A short that is helping solve problems

A Facebook group was asking: what are the best bike shorts and desotos name came up enough that I thought I'd try them! Man, they are comfy! Less saddle issues and a happier me while on the bike. I wish I had found them during my IM training but better late than never with these! So happy with my purchase

400 mile high cycling shorts

These are the best cycling shorts by far. In this case you pay for what you get and my nether regions are worth every cent that these shorts cost. Size fit excellent. I’m 5’5” 148 lb and a large fit nicely.

The shorts are comfortable for long rides. They’re the most comfortable of all my bike shorts.

400 mile shorts

I purchased the 400 mile cycling shorts in early July. Love the fit. They are so comfortable for long rides and I have even used them for some of my brick runs with no problem. They are great quality, but have developed a small tear in the seam. I have reached out and customer service has been amazing. Sending them back for repair or replacement. I can't wait to get them back for my next ride. Maybe I will order a 2nd pair so that I have them ready to go?

The size chart above should serve as a general guide. If you would like assistance in determining the proper size, please send the following information to

BUST - Fullest part of breast, measured as the largest part of circumference right over the pectoral muscle.
WAIST -  Circumference measured at the belly-button line - this is NOT the same as your pants waist size.
HIPS - Circumference measured at the widest point, NOT at your hips where your belt may go. Typically this will measure just a few inches below your hip bones and around the largest part of the glutes.


If you do not have a tape measure and you need something to measure with, use a belt, or smart phone power cord, and a ruler.
