Lefroy Pant Men's

Lefroy Pant

A technical pant designed for hiking and trekking in warm weather, the Lefroy is clear reflection of the Arc’teryx commitment to purpose driven design. It starts with the fabric. Made from Aequora AirPerm™, the Lefroy is lightweight and comfortable next the skin, and allows air to flow for evaporative cooling. The fabric’s nylon content delivers strength and quick drying capabilities, and the elastane fibres add performance stretch. The focus is on hiking and trekking, but the Lefroy’s clean, simple design results in a relaxed aesthetic suitable for travel and casual wear.


Scrambling, bushwhacking, ascents and descents require dynamic movement, and performance clothing needs to work with the body to handle shifts in terrain and topography. Arc’teryx designs with this in mind. The Lefroy’s trim fit is streamlined, but not constrictive, and articulated patterning and a gusseted crotch combine with the fabric’s four-way stretch to deliver exceptional freedom of movement. Pockets are positioned for accessibility and functionality, the waistband is specifically designed to ride comfortably under a pack, and an integrated webbing belt secures the fit.


Balancing durability with weight, the Lefroy Pant is part of Arc’teryx Traverse, a comprehensive collection of products built to explore the mountains and big terrain on foot. Comprised of footwear, packs and apparel, everything works together to deliver Arc’teryx freedom of movement, performance and reliability.

Arc'teryx Fit Guide

Trim Fit

Fits close to the body. These garments are patterned with lower volume for reduced bulk. Most compact, little room for layering.

Regular Fit

Allows for layering and freedom of movement. These garments use complex patterning and shaping to enhance motion and eliminate excess bulk.

Relaxed Fit

Has room for maximum winter layering. These garments rely on both articulation and higher volume patterns to provide comfort and mobility.

Arc'teryx Layering System

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.

The graph shows where this product sits within a layering system. Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
