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.

The Perfect Ride!

Finally someone got it right! The first time I wore the Desoto 400 Mile, I went for two long rides - 80 kilometres in two days. The shorts were perfect and were the one thing I didn't have to worry about it. Everything stayed perfectly in place. The pockets are one of the best features as I could keep my phone in the leg pocket while setting up the bike without any risk of it falling out. The only issue was that the shorts were more generous in size than I expected and I will buy one size smaller next time. Overall, I give it a huge tick of approval!

Cushion for the long haul!

I was a little hesitant when De Soto revised my favorite bike short. How could they make it any better? I already found it to be the perfect short - great pad, comfort waistband, quick drying, lots of pockets and reflective elements. I wore the updated Femme 400-Mile shorts recently for a century ride with a lot of climbing (around 6k). I had to pace myself and decided to do most of the climbing in the saddle. I never felt the pad or short shift out of place. It provided supple support and kept me cool, dry and comfortable in a very sensitive area. I couldn't imagine doing any long ride without these shorts.
