Save up to 12 Watts

Athletes can now benefit from the watt saving technology found in our record-breaking Aero-Bridge Undervest. Compared to aero socks, the extra calf coverage gives even greater aerodynamic and time savings. Saving up to 12 watts, these Calf Sleeves are the best investment on the market, with the highest £/watt aero gain.

Developed Alongside the World's Greatest

Utilising the same technology as our Aero-Bridge Undervest, the 3:Sixteen Calf Sleeve is born. Developed at the Silverstone Sports Engineering Hub and Derby Velodrome alongside the World's greatest engineers and riders. 

The Calf Sleeves were first introduced to the sporting World during the Sub7 / Sub8 challenge, with the design and name 3:Sixteen as a nod towards the 3-hour 16-minute bike leg that was achieved to help guide Joe Skipper to a sub 7-hour Ironman. The team comprised of some of the World's best time-trialists, including Alex Dowsett and recently crowned UCI Hour Record holder Dan Bigham, who crushed the opposing team to deliver one of the most incredible time trials of all time.

Patented Aero-Bridge Technology - How it Works

By stretching smooth fabric over ribbed fabric (raised ridges form a suspension of material like a suspension bridge) to disrupt the airflow by the ridge and then further alter it by the suspended fabric, causing minuscule air particles to enhance displacement of the boundary layer. 

Calf guards can be worn in triathlon competition under your wetsuit and for the duration of the event.

  • Up to 12 Watt saving.
  • Designed for the Sub7 Sub 8 record-breaking challenge.
  • Dan Bigham designed and enhanced.
  • Precisely patterned to maximise aero gains.
  • Aerodynamic materials.
  • TT and track proven.
  • For sizing, measure the widest part of the calf.

Best facial sunscreen I have used
Coola makes the best facial sunscreen, and I have tried many brands previous to using Coola. The texture is light and creamy without being oily, absorbing well and leaving no white residue. It does not clog my pores and nor cause those white bumps that last for months. Coola sunscreen works well to protect my skin from sunburn and from making more freckles and dark spots. It has no perfumy fragrance, much to my relief. Once it has dried, I can apply concealer or powder over it. No oily streaks or caking of other make-up so I have no excuse to avoid wearing this sunscreen every day. I have recommended Coola facial sunscreen to my friends who had laser dermabrasion. Their skin is more sensitive to both perfumed chemicals and sun exposure, and they have given good reports too.

Pricey, but worth it.
Coola products were included in a swag bag for a work vacation at a resort & I’ve not looked back. (The smell of the body spray sunscreen made me wish I could eat it, tbh.) This product has become my daily sunscreen as it’s the only one I’ve tried that doesn’t cause my skin to break out. I love the natural ingredients in their products AND that it doesn’t add to reef barrier breakdown. I only wish the brand wasn’t so pricey, but the benefits are worth it to me.

Terrific sunscreen!
I found out about the Sun screen from a youtuber who does Amazon favorites videos. At first, I thought she was nuts for advertising a $32 sun screen especially for the size it is. I really wanted an everyday sun screen that wasn't thick and goopy. I don't mind of I'm going to the beach or pool but a lot of them are a little much for every day use. Im trying to be better at protecting my face.. When I came across this I decided to splurge and try it. I hate to admit it but I'm so glad I did! It has a slight scent but nothing over powering at all. Its truly a weightless sunscreen that is perfect! I put it on before work and it doesn't make me look greasy or anything. You could probably use it under make up of you really wanted to, I just haven't tried it yet. My only complaint is the price but I haven't tried anything as good ad this! I've seen Ulta have sales on it every once in a while.
