Mountain Hardwear Women's Crater Lake Heavyweight Half Zip – Blackberry (Medium) | UPF 50+ Sun Protection

Overview

When mornings on the trail stretch into cool, bright hours, you need warmth without bulk and dependable sun protection. The Mountain Hardwear Crater Lake Heavyweight Half Zip delivers on both fronts with UPF 50+ coverage and a soft grid fleece backing that feels gentle against the skin. The Blackberry color brings a versatile, outdoors-ready look that pairs well with a weather-worn jacket or shell. Wear it as a stand-alone top on shoulder-season walks or layer it as a breathable, toasty baselayer for spring ski days or high-alpine excursions.

The fabric blend balances protection and comfort so you can focus on the scenery—the way the morning air hits your cheeks, the quiet of a quiet ridge, and the sense of steady warmth as you move. This piece is crafted for day-long versatility, from dew-kissed summits to sunlit switchbacks, without demanding a compromise between airflow and insulation.

Protection & Comfort

• Broad spectrum protection against UVA and UVB rays with UPF 50+ coverage
• HeiQ Mint odor control technology helps keep gear feeling fresh longer
• Smooth face fabric with a soft fleece backer for warmth without bulk
• Half-zip design for easy on/off and adjustable ventilation
• Low-profile thumbholes to keep sleeves in place during movement

Versatility & Fit

• Versatile as a standalone top or as a breathable baselayer in variable conditions
• Designed for shoulder seasons, spring skiing, and sunny high-alpine travel

Real-world use emphasizes flexibility: a chilly dawn patrol requires a quick zip for venting, while a sun-warmed ridge ride might call for full coverage to stay protected from glare. The lightweight feel allows for easy layering under a shell when weather shifts, and the overall design supports everyday outdoor activities without feeling overbuilt. The result is a dependable layer that adapts to your day, not the other way around.
