⁠How do the Delta OL 3.0 and 4.0 Tactical Winter Jacket compare?

When looking at the Delta OL 4.0 compared to the 3.0, several improvements make the 4.0 a renewed version worth noting. 

The 4.0 offers a looser fit, providing more room and comfort than its predecessor. This version also sees the hood becoming non-removable, a shift from the previous model. Adding to its features, the 4.0 includes a detachable powder skirt for better snow protection. 

The integrated hood/harness system is another upgrade, ensuring better compatibility and wearability. Plus, the face material on the 4.0 has been enhanced for greater durability and quieter movement, making it a superior choice for outdoor activities.
