The DAO is a good outdoors holster, and it does have a crossdraw feature, but it's not going to be an ideal concealment holster.
Sorry, can't find a small graphic and the one shown does not illustrate a Judge but there won't be any significant detail changes.

The Dual Action Outdoorsman holster is great for field carry whether hunting or for peace of mind in bear country.
The DAO™ can be worn strong side or crossdraw at the user’s discretion. The holster employs a retention strap for simplicity and security in the brush. The retention strap has a large polymer tab to aid in snapping and unsnapping with a gloved hand. Tension screw adjustments allow for a custom fit to your revolver.
Constructed of premium saddle leather, the DAO fits belts up to 1 3/4".
