DescriptionThe whole story▼
Smoke Blue gives the men's Knox Impass a cool, slightly grey-blue tone that looks more like a mountain jacket than motorcycle kit. It is the same lightweight waterproof shell: a 20k membrane, fully sealed seams and bonded cuffs and hem.
Knox designs the Impass to be worn over its armoured shirts. It carries no CE class and no protectors; its job is to keep wind and rain out, on the bike and off it.
Key Features
- Smoke Blue waterproof shell from the Impass Waterproof Collection
- High-performance 20k membrane: waterproof, windproof, breathable
- Seam-sealed body, cuffs and hem bonded instead of stitched
- Stretchy outer, soft interior, asymmetric main zip
- Zip-off hood with drawcord for off-bike rain
- Central water-repellent pocket with organisers plus a side pocket
- Reflective twin-stitch, integrated piping and branding
Rainproof Without Bulk
Many riders carry a rain suit they rarely put on because it is stiff and noisy. The Impass is meant to be the opposite: lightweight, soft and stretchy enough that you are happy to wear it all day. Knox describes it as a premium all-weather essential that keeps you dry and unrestricted.
Worn over a Knox armoured shirt, it turns a summer protection set-up into a wet-weather outfit in a few seconds.
Technical Details
A 20k waterproof membrane blocks rain and wind while staying breathable. Every seam is sealed, and the cuffs and hem are bonded to avoid stitch holes. The outer fabric is a soft stretch nylon blend and the inside is a smooth, brushed polyester-spandex material.
Drawcords at neck and hem and the Lift & Lock cuff closure let you seal the jacket over gloves and around the collar.
Built Around the Rider
The asymmetric main zipper reduces bulk around the collar, which Knox says makes it more comfortable on the bike. The waterproof hood zips off: useful when walking from the car park, removable when riding so it doesn't catch the wind.
The cut is designed to fit over your Knox protective layers without pinching at the shoulders or elbows.
Pockets and Visibility
A large central water-repellent zipped pocket includes organisers for phone and keys, and there is an extra side pocket. Reflective twin-stitch details, dark integrated reflective piping and reflective Knox branding catch headlights after dark.
Choosing Your Size
The Impass is cut to sit over a Knox armoured shirt, so order the size you wear in Knox upper-body garments. Knox's men's table lists chest and waist from S upwards; this colour stops at 3XL. Measure close to the body, not over a jumper, and size up if you are on the border between two sizes.
Knox's own visuals show the Impass worn over the Urbane Pro Move and with the matching overtrousers, which gives a good idea of the intended fit: relaxed enough for the armour underneath, but not baggy at speed.
Care
Rinse off road salt and grime after wet rides and wash according to the care label; a clean membrane breathes better.
What You Should Know
The Impass is a weather shell, not protective clothing: no CE rating, no armour, no armour pockets. It has no insulation, so add a warm layer in cold conditions.
Smoke Blue is available up to 3XL. Matching Impass overtrousers are sold separately.
Colour
Smoke Blue is a muted, greyish light blue. It stands out more than black in rain and fog without looking like hi-vis, and it suits travel and walking off the bike. The lighter tone shows road grime sooner than black, so a rinse after wet rides keeps it looking fresh.
