The Black Diamond Fineline Stretch Shell, previously known as the Stormline, has made its mark as an innovative rain jacket designed for various outdoor activities. Weighing in at just 9.4 ounces, it stands out for its impressive mobility and functionality in wet conditions.
"We loved the two-way stretch woven fabric for a variety of activities, with mobility rarely seen in a hardshell jacket," said Zach Lovell, the review editor. During extensive testing, the Fineline showed its potential in both light and moderate storms, proving to be a reliable companion for outdoor adventures.
The sleek design and light weight, combined with features such as a helmet-compatible hood, make it appealing. However, its sizing can be a minor hurdle, as a slimmer cut may require sizing up for those intending to wear additional layers underneath.
"At the end of the day, the Fineline Stretch is amongst the lightest fully-featured rain jackets we’ve seen yet," Lovell noted, emphasizing its competitive edge in the market.
**Reasons to Consider the Fineline**
The jacket's performance proves strong regarding its weight-to-performance ratio, along with its clean aesthetic and functional features, such as the stretchy fabric. However, some drawbacks are evident. The sizing issue may complicate matters for some users, and while it boasts decent water resistance, it may not withstand prolonged heavy rain.
When evaluating water resistance, the Fineline's BD.dry 2.5L fabric provides respectable protection against light rains but falls short during intense downpours. "Its position in the rankings was notable for those looking for an option that favors mobility,” Lovell stated. "When facing prolonged deluges, it wasn’t quite up to the job, and we got slightly wet."
Test findings confirmed that under certain conditions, such as all-day drizzles, the jacket held up well, while more severe weather led to minor water seepage. For users in typically drier climates, this option may suffice, but for heavy rain practitioners in regions like the Pacific Northwest, alternative jackets would be advisable as they may offer better protection.
Breathability remains crucial for outdoor gear, particularly during rigorous activities. The Fineline Stretch Shell is constructed with a 2.5 layer design, including a liner that positions itself next to the body. "Black Diamond's in-house fabric, BD.dry, boasts improved airflow by incorporating a substantially less 'rubbery' liner than the competition," Lovell examined. The jury is still out, as users experience varied levels of clamminess in humid conditions; some testers reported sweaty skin, although it improved during hikes in cooler temperatures.
"The Fineline offered decent enough breathability for long days outside, though it wasn't as ideal in humid conditions," noted Lovell, underscoring the jacket's limitations on warmer days.
In terms of comfort and mobility, the Fineline Stretch Shell performed admirably. "It delivered excellent results, with little restriction to our movements or lift in our midsections," Lovell explained. While not as flexible as softer materials like fleece, the two-way stretch fabric provided a pleasant level of movement flexibility, enhancing the user's experience during exertion.
Overall, the Black Diamond Fineline Stretch Shell emerges as a strong contender among lightweight rain jackets. With its thoughtful design and features ideal for moderate adventures, this jacket could fit well in an outdoor enthusiast's wardrobe, as long as they remain conscious of its limitations.
In summary, while the Black Diamond Fineline Stretch Shell excels in weight and comfort, potential buyers should weigh its water resistance and sizing challenges against their specific outdoor needs. For those looking for a jacket that balances performance with convenience, the Fineline provides a solid option, particularly for those who tackle less severe weather conditions. As outdoor gear continues to evolve, the Fineline stands as a testament to innovative design, proving that not all rain jackets are created equal.
