Polartec Power Grid: The Tried-and-True Workhorse
Polartec Power Grid has been a staple in NW Alpine’s lineup for years. If you’ve worn our Black Spider Hoody, you’ve experienced its durability and performance firsthand. We’ve had customers using this fleece for over 14 years, and it still looks and performs like new. This is the layer I wear damn near every day..
Key Features:
- Breathability & Moisture Wicking: The signature grid pattern allows air to pass through while pulling moisture away from your body.
- Warmth-to-Weight Efficiency: Provides solid insulation without excessive bulk.
- Durability: Rugged and long-lasting, making it ideal for extended backcountry trips and high-intensity activities.
- Versatility: A reliable mid-layer that performs well in a variety of conditions.
Best Use Cases:
- When durability is a priority
- Rugged alpine environments
- High-output activities where breathability is key
For those needing a bomber piece that can withstand abrasion and years of use, Power Grid is a top choice.
Polartec Alpha & Alpha Direct: Ultralight Warmth and Breathability
Polartec Alpha is a newer innovation that revolutionizes insulation. Originally developed for U.S. Special Forces, Alpha provides high breathability and excellent warmth-to-weight performance.
There are two main types:
- Polartec Alpha: Requires an outer liner for durability and wind resistance.
- Polartec Alpha Direct: A more breathable, next-to-skin version with an open-knit structure that eliminates the need for a liner.
Key Features:
- Extremely Lightweight: Alpha Direct hoodies can weigh as little as five ounces.
- Unmatched Breathability: Ideal for ultralight backpackers and high-output pursuits.
- Fast-Drying & Moisture Management: Keeps you warm even when damp, making it a great alternative to down insulation.
- Layering Versatility: Pairs well with a wind shell to maximize warmth and adaptability.
Best Use Cases:
- Ultralight backpacking (PCT, Appalachian Trail, etc.)
- Fast-and-light alpine missions (think of this as more 3 season)
- Situations where warmth-to-weight is critical
- Where the MOST breathability is needed
The trade-off? Alpha Direct is more fragile compared to Power Grid, so if you’re in a high-abrasion environment, you may want something more durable.
Which One Should You Choose?
If durability is your priority and you need a reliable, long-lasting piece, Power Grid is your best bet. If you’re counting grams and need the lightest, most breathable option for high-exertion activities, Alpha Direct is an excellent choice.
Both fabrics are incredible, and we’re excited about some new pieces coming soon that incorporate these technologies. Stay tuned for upcoming product releases that will help you gear up for your next adventure!
