Portwest KX3 Flexi Stretch Workwear
KX3 is Portwest's flexi stretch range, a slim fitting, athletic take on workwear that swaps stiff fabric for incredible comfort and flexibility. Work joggers, hoodies, softshells and bodywarmers carry practical reinforcement while looking and feeling closer to sportswear.
Lightweight stretch fabric with elasticated hems and ribbed waistbands gives a universal, move-with-you fit all shift long.
A modern slim cut that works on site and off it, popular with younger trades who want workwear that does not look like workwear.
Reinforced, articulated knee panels and holster or cargo storage keep the practicality despite the sporty cut. 31 KX3 lines available.
Sportswear comfort, workwear function. Free UK delivery on orders over £75.

About the KX3 range
KX3 reimagines workwear as athletic wear. The joggers are slim fitting with reinforced, subtly articulated knee panels for freedom of movement, a ribbed waistband and elasticated hems for a universal fit, and enough storage to stay practical. The hoodies, softshells and bodywarmers carry the same lightweight stretch comfort, so a whole outfit feels like kit you would choose to wear rather than have to.
It suits electricians, installers, delivery and warehouse roles, and any team that wants a modern look without giving up durability. Browse the range on the products page, or compare the heavier duty option in our DX4 stretch collection.
