The Kaipak Trousers from Fjällräven are a sturdy pair of men’s outdoor pants designed for hiking, trekking and general outdoor use. They balance durability with mobility, making them a reliable choice for anyone spending long days on the trail or around camp.
These trousers feature Fjällräven’s G-1000 Eco fabric—a blend of recycled polyester and organic cotton—paired with panels of quick-drying polyamide and elastane. The regular fit gives you room to move without feeling bulky, while the fluorocarbon-free impregnation adds water and dirt resistance without relying on harsh chemicals. Together, these details help the pants stand up to abrasion, speed-dry after a stream crossing, and keep you comfortable during changing conditions.
G-1000 Eco is a hardwearing textile that combines the breathability of cotton with the strength of recycled polyester. The polyamide (nylon) content in the stretch panels helps the fabric shed moisture and dry more quickly, and the elastane delivers greater flexibility at key points. The fluorocarbon-free treatment repels light rain and grime but can be refreshed with a wax or reproofing spray to maintain performance season after season.

Hardwearing trekking trousers in G-1000 with recycled polyester/organic cotton – Kaipak Trousers M are casual yet technical trekking trousers that work just as well on the trail as for everyday use. They are slightly wind and shower resistant, and readily release moisture when the pace picks up. The hybrid construction has stretch panels at the waist, crotch and back of the knees, and the articulated cut with pre-shaped knees and rear provides good freedom of movement. Two large leg pockets with discreet bellows, two hand pockets and leg endings with adjustments and boot hooks.
