These trekking pants are suitable for 3-season use, ideal for climbing the Japanese Alps during the snow-free season. The material uses Primeflex, achieving both lightweight construction and supple stretch with excellent kickback. Since it doesn't use polyurethane, it maintains its performance over a long period. In addition to the water-repellent "Omni-Shield" function that repels light rain and mud, it also features the sun protection function "Omni-Shade" to block UV rays, providing the necessary functionality for trekking. The silhouette is a neat, tapered design with moderate room around the hips and thighs, allowing for easy leg movement. The three-dimensional cut, which conforms to the shape of the knees, allows for smooth bending and leg lifting. The front pockets have zippers to prevent items from falling out, and there are smartphone-sized pockets on the right hip and the back of the left thigh. The item is meticulously designed, with an elastic waistband at the back for a comfortable fit and a nylon belt that can be adjusted with one hand. 【Features】 ・Columbia's proprietary water-repellent function "Omni-Shield" ・Columbia's proprietary sun protection function "Omni-Shade" UPF50 ・Polyurethane-free Primeflex material ・Lightweight, supple stretch, and excellent kickback ・Long-lasting performance ・Neat, tapered silhouette with moderate room ・Three-dimensional cut that conforms to the shape of the knees ・Zippered front pockets ・Smartphone-sized pockets on the right hip and back of the left thigh ・Elastic waistband at the back ・Nylon belt for one-handed size adjustment ・3-season item suitable for climbing the Japanese Alps during the snow-free season Thank you for viewing.
