Helly Hansen Alna 4X Construction Pant Class 1 are men’s lightweight and durable construction work trousers designed to meet the demands of the toughest job sites.

These trousers are crafted from a blend of 92% polyester and 8% elastane, with additional shell compositions of 94% polyamide and 6% elastane, and 100% polyamide, ensuring both flexibility and resilience. Class 1 garments have a minimum recommended level of bright background and retro-reflective materials and are worn in work environments where high vis is not crucial but keeps the wearer safely visible.

The Alna 4X Construction Pant features a 4-way stretch fabric that allows for unrestricted movement, making it ideal for active work environments. Cordura® reinforcements are strategically placed in high abrasion areas such as the knees and leg bottoms, providing extra durability where it’s needed most. The kneepad pockets are accessible from the outside, allowing for easy insertion and removal of kneepads, while the hanging pockets offer ample space for all your essential tools. Designed with a broad center back belt loop, these trousers provide extra stability and strength, ensuring they stay securely in place throughout the day. The gusset in the crotch enhances freedom of movement, making bending and stretching more comfortable.

Cordura® hanging pockets with double-lined bottoms and nylon webbing add to the trousers’ durability, while the thigh pocket with fastener closure and multiple compartments keeps your belongings organised and within reach. The ruler pocket, made from Cordura® reinforcement fabric, is perfect for keeping your measuring tools handy. Plastic-covered metal buttons add a touch of durability and safety, preventing accidental scratches or snags. Articulated knees ensure optimal mobility, and the knee pad position can be adjusted by 5 cm for a customised fit. Additionally, these work trousers have the possibility to increase the leg length by 5 cm, accommodating different heights and preferences. An ID card loop adds practicality, making it easy to display identification in work environments.

As a bluesign® product, the Alna 4X Construction Pant meets high environmental and safety standards, reflecting Helly Hansen’s commitment to sustainability. This medium price point offering from Helly Hansen combines quality, functionality, and affordability, making it an excellent choice for professionals. Easy to care for, these trousers are machine washable at 40°C, ensuring they remain fresh and ready for the next day’s challenges.
