New Size 5 is available with New Size 3 Comfort Sleeve!
As men gain size from the penis stretcher and weight hanger, Size 4 may start to feel tight. Size 5 is ideal for thicker girth and men who penis pump. 
 
Pricing is higher due to expensive tooling costs and 30% more mass all around the C-ring.
