The arm warmers with a proper bit a' Yorkshire about them.  

These Lasses Strong In't Arm Warmers are the kind that fit properly, providing the curvaceous cyclist with more choice  - based on actual arm measurements.  Designed in a super soft, thermal fabric, they'll keep your arms toasty when needed.  Simply remove if you get too warm and stash in a jersey pocket - ready to grab at the next cold spell.

Its breathable and sweat wicking fabric will keep you at a nice temperature, taking moisture off the skin - so you don't over heat and feel uncomfortable.  You'll feel just right.  Plus, with its pill resistance, you can ride bobble-free!  (And we know that can be a right pain in't head).

Who's Behind It?

Fat Lad At the Back was conceived when three 'large framed lads' including founder Richard Bye, rode to the Alps. After years of squeezing into ill-fitting and often unflattering kit, Bye decided to create a range of easy to wear, high quality garments using the best technical fabrics available.

Yorkshire-based Fat Lad At the Back ('F.L.A.B.'!) caters for cyclists who, like the founders, are fighting flab for a fitter body through cycling (their words, not ours!). Inundated by requests from female cyclists following the press and proven popularity of their male collection (including an impressive showing on the BBC's Dragons' Den), Fat Lad At the Back launched a women's specific range of plus-sized cycling clothing in response to the demand.

Launched in 2013 by Richard and his wife Lynn, Fat Lad At The Back and Fat Lass at the Back have gone from strength to strength. They design their garments in the UK and manufacture them primarily in Italy. Their focus on fit and quality is fast becoming legendary, with exceptional attention to detail in their tailoring.

*although we already suspected it, we took guidance both from our customers and from the Fat Lass at the Back themselves as to whether overt use of the brand would appeal to women as much as to men. We quickly realised that demand was strong and that many women have been hankering after plus sized women-specific cycling kit!*
