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.

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.
