External Size:

7.4″ Length x 5″ Girth


The Coast is a 7.4” long thin penis sleeve designed for those who want less girth and more length. The head of the Coast model is tapered to perfectly complement its cylindrical 5” shaft, making insertion easier. The girth of the inner hole is suited for natural girths of either 3.5” or 4”, and hard or soft erections up to 5.5” long.



  • External Girth: The girth of Coast, measured at mid-shaft, is 5”.
  • External Length: From the tip to the base, Coast measures about 7.4” long, with minimal veins.
  • Inside Length & Girth: The inside length of Coast fits a hard or soft erection up to 5.5”. The opening fits a natural girth of either 3.5” or 4”.
  • Adjustable Inner Rod: Add an adjustable inner rod if there will be a gap between you and the maximum inner length of 5.5”.
  • The Grip: The Coast model, as well as all RX Sleeves come with “The Grip” harness system to keep your sleeve in place.
  • Warranty: RX Sleeve offers a Repair or Replace Warranty for any sleeve for just $125.


The Coast is a thin penis sleeve for couples who value length more than girth. The shape, length, and girth of Coast are designed for easy insertion to help give you and your partner the experience you both desire. With an impressive external length and modest external girth, the Coast is for couples looking for an experience that’s above-average. Keep in mind that the internal length and girth are unique to you, so please consult our size guide to find the fit that will work best for you.

Don’t rule out the Coast model if your natural length is less than the 5.5” maximum that this model accommodates. You can add an adjustable inner rod to give you more control over your experience with this thin penis sleeve, filling any gap between you and your sleeve. Beyond your preferred size, you can further customize your Coast sleeve by choosing between three skin tones which best match your natural color, as well as select between two firmness options.

If you are interested in something with more girth and less length, RX Sleeve has a variety of penis sleeves to suit your personal preferences. We also offer XL Models, as well as custom options which can be made especially for you and to your specifications. If you have any questions about our sleeves, we are always happy to help. Don’t hesitate to contact us to talk to an expert. Our mission is to promote men’s sexual health and wellness by giving you options to combat erectile dysfunction.
