Overview

Men’s outerwear hunting pant combining mid-weight ripstop merino panels with stretch-nylon reinforcement in high-abrasion areas, articulated construction, removable suspenders, DWR-treated nylon and zippered storage.

WHAT MATTERS

Ripstop merino body
Mid-weight ripstop merino panels provide the principal body fabric and are designed for temperature regulation, quiet movement and odor resistance.
Reinforced abrasion zones
Corrugate Guide nylon reinforces the seat, knees, lower leg/cuff and crotch gusset.
Articulated stretch construction
Built-in stretch and articulated shaping support movement in the field.
DWR-treated nylon
Nylon reinforcement panels receive a durable water-repellent treatment.
Removable two-point suspenders
Updated removable suspension system is included with reduced hardware/contact points.
Triple-needle construction
High-stress construction uses triple stitching.
Low-noise zipper hardware
Closed-crown paracord zipper pulls reduce hard-hardware noise.
Zippered rear storage
Two rear pockets use zip closures for security.

GTW TAKE

“

Workhorse and surprisingly durable for a lighter weight pant

After roughly three seasons and 30–40 wears, the Obsidian Foundry has become my specific choice when conditions are warm enough that I don’t want a heavy hunting pant but the terrain or cover still demands more durability than an ultralight option. It earned that role on a warm Idaho elk hunt around 8,500 feet and has continued to hold up through whips and thick Maine underbrush. I would still reach for the Trace Pant in true 80°F-plus heat when rough cover isn’t a concern, and below roughly 50°F with extended stationary time I’d want more warmth. My main missing feature is thigh ventilation for dumping heat.
Warm-weather plus rough-cover sweet spot.
Strong durability-to-weight balance over three seasons.
The Trace remains the hotter-weather choice when abrasion protection is not needed.
Limited warmth for colder stationary use without additional layering.
Thigh vents would materially improve heat management.
