Sigg Army bottle holder

[Bushcrafter1]

I currently carry my water in the round Sigg water bottles and for times when I want to wander off with just the water bottle I have a neat bottle holder (made by Sigg) with a shoulder strap.

I really like the look of the new oval bottles with the cup - has anyone come across a holder with shoulder strap for them? Can't see anything on the Sigg site

Thanks
