Kalf Flux Lightweight Jacket

The Flux Lightweight Jacket has been created for mobile weather protection. Created with unpredictable conditions in mind – such as spring rides or adventures in the mountains – the jacket is supremely light and stashable.

The medium size weighs just 130g and the jacket’s fabric is windproof and is rated waterproof to 10,000mm. It is rated 60,000g/m2/24h breathable to JIS standard, with excellent flexibility. Water resistant zips and a brushed polyester fabric inside the collar add to the comfort the jacket provides. An articulated cut with a lower back panel ensures good coverage even in race positions on the bike – and the overall fit is snug (although still highly flexible) to ensure optimum weather protection and aerodynamics. Other details of the jacket include a reflective detail and elasticated cuffs.

Advanced Fabric Permeability

No compromises have been made in selecting the most advanced fabrics that push the envelope of maximum breathability. The highly advanced fabric allows sweat in the form of water vapour to leave at a high rate of transfer through the fabric, keeping you dry, warm and comfortable.

Taped Seams

When sewn, tiny holes pierce the waterproof membrane of the fabric shell. In order to make the garment 100% waterproof, the holes need to be covered using seam sealing tape. The tape is bonded using a specialist machine that uses hot air at a temperature, pressure and speed defined by the combination of tape and fabrics.

Reflective Detail

Our iridescent reflective trims and logos make for a unique aesthetic but also bring visibility to our products without visual assault.
