COLD-WEATHER OPERATIONS DEMAND SMARTER GEAR
Bulky winter gear holds you back. Traditional insulation may trap heat, but it limits movement, takes up space, and fails when wet. Whether you’re actively moving or stationary for hours in the cold, you need intelligent gear that performs consistently.

YOUR SOLUTION: DELTA OL 4.0 WINTER SUIT
- Less bulk, same warmth – Get advanced insulation that provides high thermal efficiency without the weight and restriction of conventional winter gear.
- Highly compressible, instantly ready – The insulation packs down small in your backpack and expands when you need it—no waiting.
- Unrestricted mobility – The Flex/Zone construction of the pants adapts to your movements, giving you full range of motion, and keeps insulation working effectively—without blind spots.
