OP=OP Helly Hansen Lifa Thermal Pant 75505

When you're working in warm conditions and need a base layer that actually performs, the Helly Hansen Lifa thermal pant delivers exactly what you're after. This isn't just any long underwear - it's engineered with Helly Hansen's proprietary Lifa Stay Warm technology that actively pulls moisture away from your skin, keeping you dry and comfortable even when you're putting in the hard graft. Constructed from 100% polypropylene at 125 g/m², these active long underwear trousers offer a reliable foundation for your work wardrobe. The solution and spun-dyed construction means the colour's built into the fabric itself, maintaining its integrity through repeated wear and washing. At just 151 g/m² in total weight, they're lightweight without compromising on durability. The flat seam construction eliminates chafing, whilst the seamless design removes pressure points that can irritate during a long working day. Pair these thermal pants with the matching Helly Hansen Lifa Crewneck for a complete moisture-management system.

Key Features

• Lifa Stay Warm technology pulls moisture away effectively
• Flat seams eliminate chafing during extended wear
• Seamless construction for uninterrupted comfort
• Lightweight yet durable polypropylene base layer

Recommendations from our Unishore Expert

These thermal long johns excel when you're working hard in warm environments where moisture management is critical. The fabric composition ensures perspiration moves away from your body rather than sitting against your skin, which is especially important during physical work where comfort directly affects your productivity. The seamless and flat seam design means you'll experience zero irritation, even when wearing them under tight work trousers for extended shifts. We'd recommend these for anyone who experiences discomfort from standard base layers bunching or creating pressure points. They work brilliantly as a standalone base layer or layered under your regular work wear, giving you flexibility depending on conditions.
