Compare the W's Piney Mountain UL Jacket and W's Bearsley UL Jacket from Big Agnes to find the right ultralight down layer for your adventures.
Quick answer
Choose the W's Piney Mountain UL Jacket if you prefer a hoodless mid-layer for layering under a shell; pick the W's Bearsley UL Jacket when you want an ultralight hooded jacket that can serve as your outer layer on cold, dry days.
Hood vs. no hood: the main trade-off
Both jackets share the same premium 850 Fill Power DownTek PFC-free water-repellent down and Signature Diamond Quilting, but the Piney Mountain UL is hoodless while the Bearsley UL includes a hood. That single difference changes how you use each jacket.
The hoodless Piney Mountain UL is designed to be a performance mid-layer for stop-and-go cold-weather sports, slipping easily under a hardshell or windbreaker. The Bearsley UL, with its hood, offers standalone warmth for bluebird days or as a puffy layer when you want extra head coverage without a separate hat.
Weight and packability
Both jackets are built for ultralight minimalists and disappear into your pack. The Piney Mountain UL is slightly lighter because it lacks a hood, making it the better choice for weight-conscious backpackers who always carry a shell. The Bearsley UL adds a few ounces for the hood but still packs down very small.
Trade-offs at a glance
- Hoodless design (Piney Mountain UL): Lighter and easier to layer under a shell; best for high-output activities like skiing or winter running where a hood gets in the way.
- Hooded design (Bearsley UL): Adds warmth and coverage for your head; perfect for casual wear, camp use, or as a standalone puffy on cold, dry days.
- Insulation performance: Both jackets use the same 850-fill DownTek down, so warmth per ounce is identical. The Bearsley UL's hood provides extra warmth for your head. If you always wear a hat, the hoodless Piney Mountain UL saves weight.
