Eberlestock Thunderbolt Mountain Parka - PrimaLoft Gold, Waterproof 10K

Overview

The Eberlestock Thunderbolt Mountain Parka is designed as the essential mid- and late-season piece when warmth and compressibility become indispensable. Built for mountain approaches, hunting, or extended cold-weather observation, it combines technical PrimaLoft Gold insulation with 10K-rated weather protection. A versatile garment that can be worn alone or as a mid-layer under a shell in severe cold.

Technical Features

• PrimaLoft Gold Insulation: 133g at the torso and 80g in the arms and hood, delivering targeted warmth exactly where it's needed most without excess bulk
• 10K / 10K Rating: 10K breathability and waterproofness with fully taped seams, for reliable protection against rain and snow
• Underarm zippers: allow quick heat venting during sustained physical exertion
• High-mounted hand pockets: accessible even when wearing a hip belt, with external and internal zips granting access to mid-layer pockets or a concealed holster
• Two shoulder pockets and an interior chest pocket: extra storage capacity for the essentials
• Brushed fabric: reduces friction noise while maintaining good durability
• Extended back length: elongated cut at the lower back to prevent exposure while seated, ideal for watch or observation posts

Benefits

• Consistent, long-lasting warmth, tested in extreme conditions: an Alaska hunting guide used this parka during a 60-day expedition beyond the Arctic Circle and praised its performance
• Compressible design, easy to pack away in a backpack between uses
• Pocket access designed for the active user, even when equipped with a belt or harness
• Valuable sound discretion for approaching in the natural environment
• Adaptability to changing conditions thanks to adjustments at the cuffs, hem, and hood

Use and Care

This parka works equally well on its own in moderately cold weather or as a mid-layer under a waterproof shell in harsher conditions. The DWR coating requires regular maintenance to preserve its long-term effectiveness. The Thunderbolt Mountain Parka is available in six colors (Mirage, Mountain, Skye, Dry Earth, Gunmetal, Fall Green) and sizes S to XXL, currently in stock.
