Cycling Weekly Verdict

Kask’s Wasabi helmet offers a quick and easy switch between aerodynamic optimisation and greater ventilation. For the performance minded, that might be reason enough, but there are palpable benefits for more general riding too. With merino wool padding, the helmet is pleasantly warm in wintery conditions, whilst also being notably cooler with the vent open.

Reasons to buy
  • +

    Very warm with vent closed

  • +

    Noticeably cooler with vent open

  • +

    Reasonably light for an aero helmet

Reasons to avoid
  • -

    The vertical adjustment of the retention system doesn’t always stay in place

  • -

    No front sunglasses port

The Kask Wasabi is quite rare amongst the best cycling helmets in promising to increase your aerodynamic performance as well as trapping in heat for cold weather conditions. 

But should things take a turn for the warmer, the sliding front panel allows you to draw in some cooling airflow – with a claimed aerodynamic penalty of only 1 watt at 50kph.

After winning the 2019 National Single-Speed Cross-Country Mountain Biking Championships and claiming the plushie unicorn (true story), Stefan swapped the flat-bars for drop-bars and has never looked back. 

Since then, he’s earnt his 2ⁿᵈ cat racing licence in his first season racing as a third, completed the South Downs Double in under 20 hours and Everested in under 12.

But his favourite rides are multiday bikepacking trips, with all the huge amount of cycling tech and long days spent exploring new roads and trails - as well as histories and cultures. Most recently, he’s spent two weeks riding from Budapest into the mountains of Slovakia
