Could someone please tell which harness slots my sons should be on...DS1 in red shirt and DS1 Navy shirt

Sahara cover is on top slot and Onyx is on second top slot...

Im pretty sure DS2 can stay on second top slot, but im unsure if DS1 should be on top slot as i have it...advise needed

TIA leigh

Sorry if they are a tad blurry, large and sideways I cant figure out how to rotate them..there from my phone.

Not a tech, but the pictures of DS in the navy shirt in the Onyx look like the straps are coming from below his shoulders and he needs the top slot. I remember someone saying it would be better to have the straps a little higher than too low and below the shoulders. All the rest of the pics look like they are above the shoulders and are ok.

Navy shirt definitely needs the top slots. Red shirt is fine in the second-top slots.
