Divers and snorkelers are all susceptible to dehydration and this is an enormous problem predominantly among drysuit divers. Failure to properly hydrate is a key contributing factor in most decompression incidents as people do not hydrate sufficiently because of the consequent need to urinate. Rehydration plays a vital role in the treatment of decompression illness.

The HeWee Go is the perfect solution for urination with ease, comfort and reliability. Following the success of the HeWee Go male urination system for divers, Custom Divers has been approached by other industries looking for a similar solution for applications in many different sports, work environments and also for people with disabilities. So Custom Divers has taken their experience from diving and has expanded the HeWee Go system to work equally for other activities and in diverse situations (see below HeWee Go ACTIVE for more information).

The original HeWee Go system was designed as an alternative to the conventional roll-on self-adhesive sheath. Traditionally divers have used many different brands of adhesive sheaths in their quest for comfort and reliability but the majority of these would fail during use. Those sheaths with stronger adhesives may or may not stay in place but many proved unreliable during active use and some had issues during removal. Many divers using this type of sheath would also supplement by using adhesive tape to keep them on causing consequent discomfort when worn for any length of time. And there were no alternatives… that is until Custom Divers designed the HeWee Go!

The HeWee Go urination system for men allows the user to urinate comfortably and discreetly, without the need to remove any clothing and is easy to apply and simple to use. The HeWee Go is ideal for all types of adventure sports as well as medical applications.

This unique Custom Divers design is held securely and comfortably in position by an adjustable support belt without the need for adhesives/tapes etc. The rubber flange containing the chosen diaphragm is then fitted through the reinforced ring on the front of the support belt. The sheath is then rolled over the penis to provide a good fit with any excess left rolled. This rolled section of the sheath can then be stretched over the front part of the flange where it sits and stays securely in position.

General Features
  • No adhesive or tape for fixing.
  • Comfort and Reliability.
  • Three sizes of sheaths.
  • Two sizes of diaphragm.
  • Adjustable support belt system.
  • Washable sheaths and diaphragms may be re-used up to 10+ times.
Size Guide

Your HeWee Go Starter kit comprises an adjustable support belt that is suitable for a waistline up to 40” (a 10” extension strap is available as an accessory), three different size sheaths 30, 35 and 40mm, two sizes of diaphragm (small and large), and one flange.

Once the user has chosen the appropriate size, they can then order replacement sheaths and diaphragm kits.

Quick Guide To Purchasing

Option 1 – If you are buying the HeWee Go for diving, and you already have a P-valve fitted to your suit, then select the HeWee Go Starter Kit. If you don’t have a P-valve or accessories such as a quick disconnect snap connector, then these can be purchased separately.

Option 2- If you intend to use the HeWee Go system for other activities (e.g., long-distance driving/medical) and you need to collect urine and contain it in a collection bag, then please select the HeWee Go Active system.

NB. The kits are not supplied with a tube connector or suit P-valve which may be purchased separately if required.

Fitting these parts together is simple.  A suit P-valve will need to be fitted to your dry suit, instructions on how to do this will be supplied with the valve or alternatively, your local dive suit manufacturer would be happy to install one for you.

A suit P-valve enables the user to install a valve to enable urination through dry clothing. Location is commonly fitted to the inner thigh where it can be easily reached.  On the dry side of the valve, a flexible surgical tube is connected to the sheath.

To connect your HeWee Go system to a dry suit P-valve, use the male part of the snap connector and fit it to the end of the sheath.  The female part is attached to a length of surgical hose/tube leading to the suit P-valve or a collection bag.  By simply connecting the two together you are ready to use.
