1. Slip the waist and leg straps into place, letting the D-ring fasteners settle comfortably against your hips.

3. Keep the protective pad in place for comfort, or remove it when you and your partner reach for a double-ended piece.

Can the O-ring be changed for different sizes?
The 1-3/4 inch O-ring snaps out for adjustability, so you can fine-tune the setup to your preferred insertable piece.
Will the harness stay secure during movement?
Yes. The waist and leg straps connect directly to the ring for rock solid stability, keeping everything aligned while you move.
Can I use it with a double-ended piece?
Yes. The protective pad can be removed for use with a double-ended piece, letting you and your partner share the moment.

I wanted to like this more than I do. The D ring is clearly well made and the straps feel thick enough to last, but on my frame the lower straps wanted to slide unless I really pulled them tight, and then they dug in a little. My partner appreciated the stability, so we used it a few times, but I kept having to readjust between positions. It is sturdy, no question, just less comfortable for my shape than I hoped at this price.

Fit takes a few tries to get just right, and the buckles are stiffer than I expected. Once the leg loops were even, though, the harness stayed locked in place and the D ring didn’t flex at all. I’d give it five if the adjustments were easier to fine-tune mid-play.

Bought this as a gift for my partner after her old harness wore out. She noticed the reinforced O-ring right away and said it felt much more grounded than what we had. Shipping was quick and the box was plain, which was a nice touch for a gift.

The reinforced O-ring holds firm and the adjustable straps stay where I put them.

I was skeptical because our last harness felt flimsy, but this one is a different animal. The ring is reinforced and the stitching around the straps is solid, so nothing shifts even when we get a little carried away. Honestly, it made me trust the setup.
