NASH ZT Polar Second Skins Thermal Underwear

Product benefits

The NASH ZT Polar Second Skins are thermal underwear for fishing engineered to deliver reliable warmth during your sessions at the water's edge. Worn directly against the skin or as a base layer under bulkier garments, they provide effective insulation without excess bulk—ideal for carp anglers and all static fishing exposed to the cold.

From an improved generation, this range features a finer fabric that offers better heat retention and a finish that resists pilling to maintain a neat appearance over time. The crew neck enhances thermal performance by limiting heat loss around the neck, while the considered cut allows matching tops and bottoms to fit perfectly under your outer layers.

Technical specifications

• Finer technical fabric with high insulating capacity to retain body heat in cold, waterside conditions.
• Cut specifically designed as an undergarment to be worn close to the body beneath fishing trousers or a loose jacket without restricting movement.
• Pill-resistant finish that limits fuzzing and preserves comfort through repeated use and washes.
• Crew neck design that helps retain warmth around the chest and neck while remaining compatible with most fishing jackets and hoodies.
• Range designed for anglers seeking a high-performance thermal base layer suitable for short sessions as well as extended stays.
• Suitable for use as an underlayer beneath different outer garments so you can easily adjust insulation according to season and weather.

Advantages and key points

By choosing ZT Polar Second Skins, you invest in a base-layer system that optimizes thermal comfort without compromising freedom of movement. The thin-yet-warm feel makes it easy to layer other technical garments without adding bulk, which is essential for casting, striking, and handling fishing gear with ease.

These technical garments for winter fishing are especially appreciated by anglers who spend long hours seated or motionless, exposed to wind and ambient moisture. By holding heat close to the body they reduce fatigue caused by cold and help you stay focused on detecting bites, day or night, whether on a lake bank, riverbank, or private water.

Usage advice

To fully benefit from these undergarments' performance, wear them directly against the skin to create a uniform first thermal barrier. Add a looser mid-layer if temperatures are very low, then a windproof, waterproof outer layer. This layering principle allows you to easily adjust protection by removing or adding layers as weather conditions change.

Be sure to dry your thermal underwear after each use in a well-ventilated area and follow typical care recommendations for technical textiles (gentle washing; avoid excessive drying temperatures). Regular maintenance preserves insulating power, fabric softness, and fit across seasons to reliably accompany your fishing trips.
