Black Diamond Fineline Stretch FZ regenbroek heren zwart maat M

A sudden storm hits the ridgeline and you're miles from camp. The Black Diamond Fineline Stretch FZ Pants keep you moving. Built for climbers, hikers, and backpackers who refuse to let wet weather slow them down, these men's rain pants combine a stretchy, athletic fit with fully waterproof protection. The BD.dry™ 2.5L membrane delivers 10,000 mm waterproofing and 10,000 g/m²/24hr breathability, so you stay dry from both rain and sweat. Full-length side zippers let you pull them on over boots in seconds or dump heat on a tough climb, while the elastic waistband with internal drawcord ensures a secure fit. When the sun returns, the pants pack into their own rear pocket, disappearing into your pack until the next downpour.

Key specifications

• Waterproof and breathable BD.dry™ 2.5L membrane (10,000 mm / 10,000 g/m²/24hr)
• Stretch nylon fabric with DWR finish for mobility and weather resistance
• Fully taped seams keep moisture out
• Full-length side zippers for easy on/off and ventilation
• Elastic waistband with internal drawcord

• Slim, athletic fit designed for layering

Why choose it

The Fineline Stretch FZ Pants are built for dynamic movement in wet conditions. The stretch fabric moves with you while climbing or scrambling, and the 2.5L membrane balances waterproofness with breathability, preventing that clammy feeling common in cheaper rain gear. The full-length zippers are a game-changer when you need to quickly pull them over boots or dump heat on a steep approach.

Ideal use cases

• Alpine climbing and mountaineering in unpredictable weather
• Backpacking trips where weight and packability matter
• Hiking in rainy or windy conditions
• Emergency rain protection for trail runners and fastpackers

Good to know

The pants pack into their own rear pocket, making them easy to stash in a pack or clip to a harness. The slim fit layers comfortably over baselayers without restricting movement, and the DWR finish sheds light precipitation between washes.
