What we measured
Why this score?
The Black Diamond Fineline Stretch is a highly regarded, lightweight, and mobile rain shell that offers excellent value for hikers, climbers, and backpackers.

Pros
- Excellent mobility and comfort due to stretchy face fabric
- Very lightweight and highly packable for backcountry use
- Includes useful features like pit zips, helmet-compatible hood, and carabiner clip loop
- Competitive price for a feature-rich technical shell
Cons
- 2.5-layer construction is less durable and loses waterproofing faster than 3-layer jackets
- Breathability can feel limited during high-exertion activities despite pit zips
- Interior fabric can feel slightly sticky when wet
- Slim fit may restrict heavy layering underneath
⚠ Red flags
- Contains PFAS in some versions; cannot be shipped to certain US states (CA, NY, CO)
- Past season/outlet items are often final sale with no returns or exchanges
Better options
Why switch: Uses a more durable 3-layer construction which typically offers better long-term waterproofing and longevity compared to the 2.5-layer Fineline Stretch.
A higher-end option if looking for more advanced technical mountain performance, though at a significantly higher price point.
