I have been experimenting with the Sabre Skin over the past months or so. that it is best to wear it in two separate layers. This makes for a much better proportioned girth to the respective length gain. This also effectively prevents the glans from slipping past the edge of the sleeve when sitting.
As you have various girths you can experiment to find the right combination for the best performance. I wear a couple of 24 girths and they work really well. Btw. I also wear the fully adjustable Ball Strap plus Mag-Volt in combination with the Sabre Skins.
One customer reported that he uses a hot air blow dryer to shrink the sleeve girth to good effect but I never had the need so I haven’t tried it yet. Maybe I will do some experimenting to see how it works.
Anyway, try double layers with the different girths to find the best combination and let us know how it goes.
