Black Diamond’s Performance Rainwear 

Black Diamond is an outdoor adventure company that has proven themselves to be high quality and innovative, over and over again. Like most of the best outdoor apparel and gear companies, Black Diamond was started in a backyard with nothing more than a vision and a tool kit. Today they are a global company with offices on three continents. Black Diamond is all about climbing and skiing, but their gear is not just for climbers and skiers. They dream of innovation and apply this dream to products that will showcase their values and technical skills. Since the 50’s Black Diamond has been working on creating gear that doesn’t just meet the standards in each area, but exceeds them, lifting the bar for all to reach.

Black Diamond is a company that has shown they will not stop pushing the envelope of innovation and creativity. Because of this, their gear is some of the best on the market. Like the best in the industry, Black Diamond fulfills its obligation to protect the environment it is designed to enjoy. Their sustainability mission is rooted in the combination of conservation, preservation, and access to mountain, crag and canyon environments all while minimizing their environmental footprint. At their headquarters in Utah they utilize a solar photovoltaic system that produces efficient and green energy to power their production. They are also a founding member of the Outdoor Industry Association’s Climate Action Corps which advocates for sustainable recreation practice, trade policy, ethical business innovation and increasing outdoor participation for all (LINK).

Environmental responsibility goes hand-in-hand with social responsibility for Black Diamond. They aim to tackle the need for greater education of best practices in social compliance in the outdoor industry, through their work at the Outdoor Industry Association’s Fair Labor Working Group.

Black Diamond’s Rain Performance Gear 

Black Diamond Equipment has long worked to better their products and their environmental and social impacts. Their Rain Performance Gear perfectly showcases their innovation paired with style, and technicality. Here are some of our favorite pieces from the Rain Performance Gear Collection. 

Treeline Tree Shell

Coming in both men’s sizes and women’s, this shell is a great buffer layer to fight any rain you may encounter on your adventure! Black Diamond utilizes their BD.dry(tm) waterproof, windproof, and breathable solution to equip the shell to shield you from those mountain showers while you’re cruising the trails. It is fully seam-sealed, so water does not have a chance to sneak in. It comes in six colors, so you can match it to your outdoor wardrobe. 

Key Features: 

  • BD.dry ™ technology 
  • 10,000mm waterproof rating 
  • Single-adjust climbing-helmet compatible hood perfect if you find yourself needing a rain layer while climbing 
  • Back vent with mesh pockets for additional air flow

Stormline Stretch Rainshell

The Stormline Stretch Rainshell comes in both women’s and men’s sizes. This one is a favorite because of its versatility. This is the perfect layer from spits of rain in the mountains to downpours in the city. The Stormline Rainshell is designed to handle anything thrown at it. It is not too heavy that it would be uncomfortable to wear during a light rain in the mountains, but is heavy enough to keep you dry in a complete downpour. It comes in 9 colors, making it easy to match to your style, both on the trail and in the city. 

Key Features:

  • Built with BD.dry ™ technology, Black Diamond’s engineered waterproof, windproof, and breathable material 
  • Stretch shell fabric designed to increase durability and comfort
  • Underarm gussets for additional mobility if you find that you need it 
  • Extremely easy to pack, it folds into its own pocket, making it easy to bring along anywhere you may need it.  
  • Adjustable cuffs and hem

Fineline Stretch Rainshell 

The Fineline Stretch Rainshell is a similar design to the Stormline Stretch Rainshell. Coming in both men and women’s sizes, the Fineline shell is a great layer to bring along with you no matter what outdoor activity you are participating in. Black Diamond called this rainshell Fineline because sometimes when you are in the mountains, there is a fine line between perfectly blue skies and down pouring thunderstorms. This rainshell is designed to perfectly protect you during these storms, while staying lightweight and comfortable enough to allow you to continue your outdoor activities! 

Key Features: 

  • Made with BD.dry technology engineered to shield you from whatever the weather has in store 
  • Optimized for mobility by utilizing underarm gussets and a stretch fabric 
  • Comes with an adjustable, climbing compatible hood that you can utilize at any second

Stormline Stretch Rain Pants 

The Stormline Stretch Rain Pants come in both men and women’s sizes. These rain pants are extremely lightweight, allowing for maximum mobility and protection when the weather takes a turn for the worst. These pants are extremely sleek and packable, while also durable and versatile. You can utilize these pants while hiking, backpacking, and even climbing. 

Key Features: 

  • Equipped with a gusseted seat and roomy knees, these pants will not hold back your mobility at all
  • Comes with a 1/3-length zipper on either leg with a snap-adjust bottom hem and an elastic waist with a drawcord, to give you a customized fit
  • Back zippered pocket to keep your valuables secure

No matter what you find yourself missing for this season, you should head to Black Diamond Equipment and check out their gear. They have earned their reputation as a trusted and valuable company in this industry and their Performance Rainwear Collection shows that.

The Black Diamond Treeline Stretch Rain Shell

By utilizing their BD.dry™ waterproof/breathable/windproof solution, the Treeline Rain Shell comes at a value and is engineered to shield you from mountain showers while cruising the trails. Featuring a 2.5-layer 10K/10K stretch fabric that’s fully seam-sealed, the Treeline is breathable and moves with you while on the go but remains 100% windproof and waterproof. A Vislon™ waterproof front zipper keeps moisture out, while the DWR pit zips add ventilation. Black Diamond also included two backpack-friendly zip hand-pockets to store your on-trail essentials. The StormForm™ single-adjust hood protects you in the heaviest downpours while the adjustable hem and cuffs dial in the fit on the move.
