Size depends on how you sit in the woods.

Regular size sit on the ground or low profile chair (6 inches off the ground)

XL size allows you to sit low to the ground up to normal chair height.

No - if you only sit on the ground the XL blind is one foot wider to set up and is harder to tuck into tight areas and doesn’t provide you any more cover. 

Sit back from the blind use it as a screen out in front this allows you room to be able to pull up and shoot off the sides as well as through the windows.

Blind is designed to be stake free and most of the time it doesn’t need to be staked down. On real windy days, each corner has loops for stakes.

We believe the 3D Leafy blinds work better to fool a whitetail.

This blind provides cover for you to get drawn, sit back so you can shoot off the sides or through the windows.

Unless you draw a bow back and shoot off the ground, most hunters prefer the XL. 

The double up system is 2 Nukem blinds plus a center panel, blinds can be used separate or with the system.
