KLIM Men's Inferno Mid-Layer Jacket - Lightweight Fleece Midlayer

In this review the KLIM Men's Inferno Mid-Layer Jacket is judged as a practical, low-bulk insulating layer for colder rides and winter activity. The bottom line: it is for riders and outdoor users who need a warm, breathable midlayer that fits neatly under outer shells and motorcycle jackets; the single biggest reason to buy is its balance of warmth and mobility thanks to a 4-way stretch polyester fleece construction that moves with you without adding bulk. The jacket reads like a purpose-built mid garment rather than a heavy standalone coat.

Key Features

• Polyester Fleece/Spandex Construction: Delivers a flexible, close-fitting layer that stretches for comfort while maintaining shape under a shell.
• 310 Gram Weight: Provides substantial insulation for a midlayer while staying lightweight enough to avoid trapping heat against outer layers.
• Low Bulk: Designed to layer easily under protective motorcycle or snowmobile jackets without restricting movement or fit.
• Anti-Pilling Fleece: Keeps the fabric looking newer longer when worn under gear and after repeated use.
• Highly Moisture Wicking and Breathable: Moves sweat away from the body so it works well during active rides or snowmobiling days when you need climate control.

Who It's For

The Inferno mid-layer suits motorcyclists, snowmobilers, and outdoor workers who want a slim, warm garment that fits under a protective outer layer. Its fit and stretch make it especially good for anyone who needs the jacket to play well with armor or bulky outer shells.

Those who want a heavy winter parka or a standalone shell with windproof outer fabric should look elsewhere; this is a mid-layer optimized for insulation and mobility rather than a weatherproof outer garment. If you need integrated waterproofing or thick, standalone insulation, choose a different jacket.
