The alternative to the rainy Nanoflex+ warmers. The Thermoflex warmers concentrate on getting everything just right. The fabric is extra warm and stretchy, the fit eliminates any extra fabric, the silicone gripper at the top prevents the warmers from falling down, and the cross-wrap cuff at the bottom gives a touch of extra comfort to keep the chill off your arms on cooler days. Perfect for chilly mornings.

Who's Behind It?

Q. What do a 19th century Italian tailor, a designer for the Milan Ballet and the first ever lycra cycling shorts have in common?

A. They are all part of a rich 140 year history that's led to today's most recognised brand in cycling: Castelli.

Throw in a heart attack on a famous Italian climb, family feuds, Olympic gold medals and controversy in the pro peloton and it begins to sound more like a Sicilian soap opera than the backdrop to a cycling brand. But then again Castelli is no ordinary brand.

Today, Castelli's scorpion emblem is arguably the single most recognised in cycling. Iconic is an overused word these days, but the Castelli brand surely qualifies.

We first discovered Castelli on our year long ride through the Americas in 2010, when our founder Liz (pictured) wore Castelli shorts and loved them, so stocking them seemed an obvious choice. But we're almost as captivated by the story behind the name as the kit itself!

  1. Amazing product and brilliant service

    Review by MJ

    I am a man but a small man (although much to my Wife's amusement our twin boys who are 3 1/2 say I am big) I had bought arm sleeves but they kept falling down. This product is just perfect, does not come down, feels secure and keeps you warm, What more can you ask for. I was also really amazed by level of service, I ordered on 48 hour delivery and checked on line order was 'processing' I emailed and was contacted straight away saying they would put order on next day delivery which they did and it arrived as promised.

    VeloVixen Says: MJ - we're very flattered and delighted that they're working for you! x
