So the lendenier got a lot of harness time this past weekend at a living history timeline event called 'Days of Knights' in Kentucky and I thought I'd share my thoughts and a little 'after action report.'
I wore the lendenier for about 7 hours each day, with leg harness on for probably about 4 hours each day . When I stripped the top half of the armor, or before fully harnessing up I kept the leg harness suspended to maximize the lendenier's time of use. Overall it was a great experience.
Without leg harness on with the lendener under my arming doublet, it is completely transparent to you. Sitting, standing, walking, running etc are completely unaffected. There was never a point where I was aware that I had an extra garment on by feel. It felt virtually the same as if I'd only had my pourpoint on.
When you do point your leg harness to it, it will settle as you wear it over 10 minutes or so. I found jumping up and down and moving around after initially pointing your legs will accelerate that process and help it find its final spot. Once it's there it's rock solid. Over the course of wearing my legs for several hours with the lendener, I would occasionally have to re-truss the points to tighten them, but that was independent on the lendenier and just a result of the points themselves loosening a bit over time (something that can be remedied by re-waxing them), but some of that is unavoidable. Compared to the leather version I made, the textile version is considerably more comfortable over time. Based on this weekend, the textile lendener is my preferred method of leg suspension (as compared to the leather version or using the doublet directly).
Here is the final state of the textile lendenier and the harness I wore it with:
