Outdoor Research Allies Colossus II Parka | Extreme Cold Weather Protection

Mission-Ready Warmth When Everything Else Shuts Down
When the temperature drops and your mobility hits zero, the Allies Colossus II Parka kicks in. Engineered for Arctic-level cold and static operations, this is Outdoor Research’s warmest outer layer- trusted in polar environments, proven in the field.

Built with a Cordura® shell and AscentShell™ Dry membrane, the Colossus II balances weatherproof performance with rugged durability. Inside, it’s packed with VerticalX™ insulation, locking in heat while keeping you breathable and dry under pressure. From shoulder ID patches to fleece gaiters and forearm stash pockets, every feature was designed for operational advantage in extreme climates.

Why We Love It

This is not your average parka. It’s the kind of layer you reach for when you’re glassing a frozen ridgeline, sitting static on surveillance, or surviving through zero-dark-below. Arctic-tested and elite-approved.
