Fair enough. I was much skinnier when I was wearing webbing years ago (weren’t we all?) so I am not entirely sure how much weight is carried by the average crewman these days. Years ago it wasn’t much.Got to disagree with this, good webbing should spread the load, some on your shoulders some direct onto your hips. The human back is actually pretty poor at carrying weight.
Some further thoughts for the op: if they are a racing snake and not much weight is being carried, could this be causing the equipment to come loose?
My reasoning is that equipment needs some load on to hang together.
ETA: seen the above. Seems a bit sad that a mate in the unit could not have helped out.
