Don't waste your money , too tight, worst ever, don't buy.

Nothing special. Less than impressed by the sensation of it

I purchased the Pile as an alternative to the Zen. I love the material, depth, contact surface and most everything about the 3D series. I have a GEO Coral that I love so this texture seems similar. Well let me tell you, if your looking for a sensation of grip and suction, this is it. The texture is soft but effective for stimulation throughout the length/depth of the sleeve. I will use this as my mood feels the need but my go-to is the ZEN.

have pile and zen. pile is more stimulating but sensation is quite odd, i recommend for a quick relief.
zen is dull but better for long lasting and training stamina and faster to clean.

The 3D pile is similar to Geo Cup coral sensation wise, with out the tug factor. As an enhancement of you package profile under very formfitting swim trunks, jeans or shorts it should definitely improve your social life. As intended as a stoker its functional with your firm grip.

if ur even kinda big they will eventually break. Hard pass.
