Frequently asked questions

Is this jacket actually waterproof?

Yes. The outer shell has taped seams and meets EN 343 Class 3 (20,000mm water resistance), with a PFAS-free Texpel Splash Eco finish on top.

What does '5-in-1' mean?

The outer waterproof jacket and inner jacket separate, and the inner jacket's fleece sleeves detach, so you get five wearing options from one jacket.

How cold can I wear this in?

It's EN 342 certified for cold protection down to -36°C, with a high-insulation inner layer for very cold conditions.

How many pockets does it have?

Six in total, including two outer patch pockets, an inner chest pocket, two inner side pockets and a concealed mobile phone pocket.

What sizes and colours are available?

Sizes run from XS to 5XL in a unisex fit, in orange/navy, yellow/black or yellow/navy.

Does the hi-vis rating survive washing?

Yes. It's certified to EN ISO 20471 Class 3 after 50 washes.

Can I brand this jacket for my company?

Yes. Embroidery and print branding are both available - ask about trade-account pricing for bulk orders.
