Crater IV HS Hooded Jacket

The Mammut Crater IV HS Hooded Jacket is a workhorse shell built for serious weather, featuring 3-layer GORE-TEX construction. This isn't a jacket for fair-weather hiking; it's designed to keep you dry and comfortable when the skies truly open up and the wind howls. The 3-layer laminate offers robust waterproofness and breathability, a critical balance when you're exerting yourself in wet conditions. Mammut has done well with the cut, allowing for layering underneath without feeling overly baggy. It's a jacket that feels substantial without being overly heavy, aiming for that sweet spot of durability and packability.

In the field, the Crater IV performs as expected from a high-quality GORE-TEX shell. The hood is well-designed, offering good coverage and adjustability to batten down the hatches against driving rain without impeding vision significantly. The zippers are robust and easy to operate, even with gloves, and the pit zips are a welcome addition for dumping heat quickly on the ascent. While it’s not the lightest or most packable shell on the market, it prioritizes reliable protection over minimal weight, which is a sensible trade-off for its intended use. You'll notice the durability in the ripstop face fabric and the overall construction quality; this jacket feels like it will stand up to years of abuse.

Compared to ultra-light shells, the Crater IV offers a significant step up in bombproof protection and longevity. It sits squarely in the mid-to-upper tier of hardshell jackets, competing with offerings from brands like Arc'teryx or Patagonia in terms of performance and build quality, often at a slightly more accessible price point. This jacket is really for those who demand reliable waterproof and windproof protection for multi-day trips or in areas known for unpredictable, harsh mountain weather, rather than someone looking for an emergency-only layer for day hikes.
