All day sun protection that never wears off.
A first of its kind, our Summerweight Jersey is the perfect solution to protect your skin from prolonged sun exposure. Like air conditioning for your skin, this weightless fabric allows breeze to pass through while UPF 50+ protection keeps harmful UV rays out, and will actually keep you cooler on the hottest summer days.

No matter how many times we reapplied sunscreen on rides, our skin was still exposed to harmful UV rays which, over time, can lead to melanoma and early signs of aging. We wanted a physical barrier against the sun. Something that didn't wear off, sweat off, or require constant re-application, and the Summerweight Jersey is our solution.
Turns out, this highly breathable barrier also keeps you cooler on the hottest days! By trapping moisture on the skin, it provides an air conditioning effect the minute you start moving and the wind hits your skin.
- Ultra Lightweight fabric that allows breeze to pass right through.
- Moisture Wicking
- Quick Dry
- UPF 50+ protects your skin from sun damage.
- Signature Reflective Details
- Three full sized back pockets to store everything you need for all day rides without sagging.
- Additional secured zipper pocket with moisture barrier for keys and cards.
- Four way stretch for fantastic fit.
- Top quality, self-locking, zippers that lie flat.
A snug fit is crucial to performance!

To get the longest life out of your garment, we recommend washing in cold water with a mild detergent and hanging it to dry. If you need to toss it in the dryer in a pinch, that's okay! Just keep this to a minimum. Overtime, heat can degrade the yarn, resulting in lost compression and durability.
All orders are shipped free within the US, and will include a pre-paid return label for easy returns and exchanges.
If ordering from outside of the US, be sure to check local duties and taxes! Machines does not cover this cost and rates vary country to country.

For cycling bibs and shorts, the HIP MEASUREMENT is the most crucial factor. Measure around the WIDEST POINT of the hips/bum. If you are between sizes or petite (5'3" or under), we recommend SIZING DOWN for a compressive fit. A snug fit is crucial to performance. Check out our FIT GUIDE for more detailed instructions, or pop your measurements into the fit calculator above for a personalized recommendation! (Please note, the fit guide requires chest, waist and hip measurements.)
Fabulous fit and fabric. Highly recommend this jersey. So comfortable in hot conditions and great to know you are sun safe. Thank you.
I love MFF tops they look great and make me feel great. The light weight Lycra is such a delight to wear and the long sleeves are great for sun protection. Other cyclists often compliment me on them….even blokes!
I have another one of these jerseys and love it and looking forward to many comfortable rides in my new jersey!
I have 2 of these jerseys and absolutely love both of them - especially the silky feel of them. And, of course, I get lots of compliments when I wear either of them - the one that you are showing and an earlier purchase which has "palm leaves - blacks, greens, whites and salmon.
I have several MFF jerseys and I love them all. I most recently purchased Midnight Bloom since I am drawn to florals. The rich purple background with its big flowers make this top very special.
