The main advantage of small capacity leg bags is their discreet nature. The smaller and lower profile size of small capacity leg bags may be a good choice for when you’re out and about, switching to a larger leg bag when you’re at home and discretion isn’t as important. Smaller leg bags are also lighter, so could also be a good option for those living an active lifestyle.

The average bladder can generally hold 400-600ml of urine, so medium capacity leg bags are suitable for most people. Medium sized leg bags can still offer some of the discreet advantages of smaller bags, whilst also providing the capacity for less frequent trips to the toilet to empty it.

When you’re at home and discretion is less important, large capacity leg bags may be a good option. They can sometimes hold up to two times the volume of the average bladder, meaning less trips to the toilet to empty your bag. It’s worth noting with the extra capacity these leg bags can get quite heavy, so you must make sure you are using the correct fixation devices for supporting the bag.

Direct inlet tubes are the shortest option for leg bag tubing. They usually range from 0cm to 5cm, and are designed for those requiring a very short inlet tube. For indwelling & suprapubic catheter users, direct inlet bags would generally sit on the upper thigh, and could be a good option for those looking to hide their bags when wearing shorter clothing.

Short tubes range from 5cm to 10cm depending on the leg bag manufacturer, and long tube leg bags are often around 25cm. Generally short tube leg bags would sit on the thigh, keeping the inlet tubing relatively straight to avoid kinking. Long tube leg bags my be better choice for those who prefer to wear their leg bag lower down the leg (like on the calf), or require more tubing for a comfortable fit.

Some manufacturers now offer adjustable tubing options. This is where the bag, inlet tubing and universal stepped connector can all be disconnected, allowing you to cut the inlet tubing to the desired size before re-attaching the connector and bag. This could be a good option if you’re in between standard sizing.

Lever taps usually open 180 degrees, but often drain from 90 degrees onwards, giving users more control over output speed. Due to the flat shape of a lever tap when closed, they can be a more discreet & ergonomic option to wear under clothing on leg bags.

T taps are available in two formats, reusable t taps, often found on leg bags where the bag is designed to be emptied multiple times. Or single-use t taps, often found on single-use night drainage bags, where the t tap mechanism will lock after being opened, preventing it from being closed again.

Clamp taps are the simplest drainage bag tap option. They work by clamping the outlet tube to prevent fluid from exiting the bag. The simple design is reliable and discreet, but may not be suitable for those with limited dexterity as they often require more force to be opened and closed. They are often only found on leg bags.

Bung caps are only found on Coloplast Conveen Active Leg Bags. They're used on these leg bags to provide a lightweight drainage option which doesn't compromise the low profile nature of the bags.
