Gamakatsu Padded Pants (Thermolite) GM3601 Black SS

Uses "Thermolite", a hollow functional yarn filling material that provides excellent warmth, mobility, and heat retention.
The main body material is also made of a lightweight material with improved abrasion resistance, making it an item that can be worn in a wide range of situations, not just for fishing, but also as a travel outfit or innerwear.
Uses Thermolite HL1 filling, which has the optimal balance between light weight, heat retention, and a soft feel.
The lining is made of lightweight polyester fabric with high strength and excellent texture.
It slides well and does not hinder movement even when layered with a rain suit or other clothing.
Machine washable

Functional material designed to keep you warm even in the harshest of cold environments
The highly thermally effective macaroni-shaped hollow fibers and ultra-fine fibers retain body heat and prevent cooling due to heat radiation, providing a heat retention effect
When you are hot and sweaty, its excellent evaporation effect suppresses the rise in body temperature and controls comfortable warmth
The fiber itself is made of ultra-fine fibers that are of higher quality than silk, so the surface area is 20 times that of polyester cotton. By trapping more fiber and air in the same volume, it has the same heat retention power with 1/2 the thickness of down.
It dries quickly even when wet, so there is no need to worry about losing fluffiness. It can be easily washed in the washing machine, making it extremely easy to use.
