  • From day one, our Chugach Rain Gear System has earned its keep on tough unsupported backcountry hunts when staying dry, covering miles of country, and keeping overall gear weight to a minimum are crucial. The redefined Chugach TR is now more waterproof, stronger, and lighter than ever before.

    Revamped with Toray's Torain (TR) Waterproof Technology, the new Chugach rain gear system performs better than ever.
    • Nearly 20% reduction (5.4 oz) in combined jacket and pant weight
    • 400% increase in abrasion resistance
    • 20% increase in tear strength
    • Improved hydrolysis resistance for extended garment life
    • Instantaneous and more balanced breathability
    • Ultra-fast dry time
    The result is a packable rain gear system with the durability for extreme mountain hunts, plus excellent breathability and stretch to keep hunters comfortable even at high levels of exertion. This full-featured rain pant includes an adjustable waist with built-in belt, full-length side zippers for easy on/off and ventilation, articulated knees for unrestricted performance, gusseted crotch for mobility, and Bemis overlay film scuff guards for added durability.

    The seams in any garment add weight, introduce potential failure points, and are less water resistant. The new Chugach TR leverages a strategic build to eliminate seams wherever possible. This streamlined design is more durable, lighter weight, and has less bulk while packed.

    Featuring comfortable 4-way stretch Primeflex Nylon fabric, the Chugach TR does not restrict your movements, keeping you free to step over downed timber and climb in steep terrain.

    • Adjustable waist with built-in belt
    • Zippered fly
    • Full-length side zippers
    • Articulated knees
    • Gusseted crotch
    • Bemis overlay film scuff guards
    • YKK Aquaguard zippers
    • Fully seam taped
    Built with an outer-layer fit, the Chugach TR Rain Pant is ideally worn over a base layer and an insulating mid layer or over your main outer shell all in your same measured size. Layering example for cold and wet conditions (All size Large):
    • Base Layer: Peloton 118 zip-off bottom
    • Mid Layer Insulation: Kenai Pant
    • Rain Shell: Chugach TR Rain Pant

    Built-In Technology


    Unlike ordinary waterproof fabrics, Torain combines premium spandex-free Primeflex face fabrics, with a highly breathable Dermizax HDM microporous hydrophobic membrane, and circular knit backer. The fully seam-taped system provides waterproof performance the competition can’t match. You get enhanced breathability, lower water retention, increased hydrolysis resistance, and better long-term durability.

    • Torain 3-layer fabric: 130 g/m²
    • Face fabric: Toray Primeflex Nylon 6/10, 50D
    • Membrane: Dermizax HDM microporous hydrophobic membrane
    • Torain seam taped waterproof construction
    • 4-way stretch
    • K-DWR water resistance
    • 30,800mm waterproofness
    • Breathability (A1 test): 10,000g/m²/24hrs
    • Breathability (B1 test): 18,400g/m²/24hrs

    Fabrics that get their stretch from as much as 10% elastane, spandex, and Lycra® materials are heavy, slow to dry, and don’t last. Primeflex Nylon fabrics solve the problem of restrictive clothing by utilizing a patented spiral yarn that allows the fabric to stretch and recover without using water-absorbing spandex. Primeflex fabrics are quick dry and offer durability, comfort, and stretch without the weight.


    Once a fabric is soaked, insulation and breathability are compromised. K-DWR treatments bead and resist water, keeping it from penetrating the outer layer. This increased breathability and performance allow waterproof membranes to evaporate your sweat while blocking out moisture. K-DWR also enhances dry-time and protects from light rain or dew-soaked vegetation on non-waterproof products.
