Helly Hansen Men H1 Base Layer 3/4 Pants – Navy NSF

The Helly Hansen Men’s H1 Pro Seamless Graphene 3/4 Pants are a technical, high-performance cropped base layer engineered specifically for skiers, racers, and winter outdoor professionals. Utilizing a seamless, body-mapped construction that eliminates lower-leg bunching inside ski boots, this three-quarter-length thermal pant integrates advanced graphene fibers directly into the textile matrix to deliver active thermoregulation and natural odor control during high-output mountain activities.

Key Features

• H1 PRO LIFA® seamless construction engineered to eliminate structural seams across major friction zones, completely preventing chafing and next-to-skin irritation.

• Advanced Kyorene® Graphene Fiber technology woven into the yarn to provide natural, long-lasting odor control and high-efficiency core thermoregulation.

• Specialized boot-fit architecture utilizing a 3/4-length cropped design that ends precisely above the calf to prevent uncomfortable pressure points inside tight ski boots.

• Precision anatomical body-mapping technology integrating targeted ventilation zones and insulation panels based on the body’s natural heat-release patterns.

• Extended protective silhouette featuring an elevated high waist configuration for extra thermal core coverage, kidney warmth, and secure layering lock.

Construction & Fit

• Precision fitted silhouette designed to sit flush against the skin, maximizing rapid capillary moisture transport away from the body during intense runs.

• Technical composite fabrication crafted from a highly flexible, moisture-resistant blend of 47% Polyamide, 37% Polypropylene, and 16% Elastane for multi-directional stretch.

• Secure perimeter retention featuring a low-profile ribbed bottom hem that anchors the cropped leg cuffs comfortably in place to prevent riding up.

• Lightweight alpine build weighing a minimal 310g, engineered to ensure high breathability, fast drying times, and zero structural restrictions to lower-body mobility.
