Choosing the correct size for your Orca wetsuit boots, gloves and swim cap is essential for staying warm and comfortable during cold water swimming and open water sessions. Properly fitting accessories help reduce water flushing, improve insulation and allow better movement in the water. Use our Orca wetsuit boots, gloves and caps size guide below to compare measurements and find the best fit for your next swim.
Cold water swimming accessories can make a huge difference to your comfort and performance in lower temperatures. Whether you are swimming through winter, training outdoors regularly or preparing for long-distance open water events, choosing the right size Orca wetsuit boots, gloves and hood helps you stay warmer for longer while maintaining comfort and flexibility.
Orca designs swimming accessories specifically for open water swimmers and triathletes, focusing on warmth, hydrodynamics, flexibility and reduced water entry. A close-fitting accessory helps improve insulation and overall comfort, while incorrect sizing can lead to excess water flushing, discomfort or restricted movement.
Use the Orca size charts below to compare your measurements and find the correct size for your swimming accessories.
Orca wetsuit accessories are designed to fit snugly against the body to minimise water circulation and retain warmth. They should feel secure without causing pain, numbness or excessive restriction.
Orca swim boots should fit closely around the foot and ankle without large gaps or movement inside the boot. A secure fit improves warmth and helps maintain better connection and control while entering and exiting the water.
Swimming gloves should fit tightly around the fingers and palms while still allowing natural hand movement. Gloves that are too loose may fill with water quickly, while overly tight gloves can reduce circulation and comfort.
A wetsuit hood should sit close around the head, neck and chin to help trap warmth and reduce cold water exposure. The fit should feel comfortable without restricting breathing or movement.

The best swimming accessories for you will depend on the water temperature, your cold tolerance and the type of swimming you do most often.
You may want to consider:
For colder UK winter conditions, many swimmers combine neoprene gloves, boots and a hood for maximum thermal protection during longer swims.
For the best fit, measure carefully before comparing your sizing against the Orca charts below.
Measure your regular shoe size and consider whether you prefer a tighter performance fit or slightly more room for comfort and warmth.
Measure around the widest part of your hand and compare against the recommended glove sizing.
Measure around the circumference of your head just above the ears for the most accurate hood sizing.
If you are between sizes, the ideal option will usually depend on whether you prioritise warmth, flexibility or ease of movement.
