Who Can Use the Sigvaris Coolflex Adjustable Compression Sleeve?

The Sigvaris Coolflex Sleeve can be used by anyone requiring compression therapy, but is especially well-suited to those with open wounds or sensitive skin. Made with a light, mesh material, it provides effective compression therapy while encouraging the healthy recovery of active injuries.


The sleeve can be used for the following conditions and uses:

  • Chronic Venous Disease
  • Venous Leg Ulcers
  • Post-thrombotic Syndrome
  • Phlebolymphoedema
  • Lymphoedema
  • Dependent Oedema

What Makes the Sigvaris Coolflex Compression Sleeve Different?

  • Spacer mesh fabric is incredibly breathable and lightweight
  • Lateral straps are easy to apply and adjust by the patient
  • Built-in visual indicators ensure users can achieve an accurate level of compression
  • Metal hooks improve the durability of the sleeve
  • Basic liners are moisture-wicking and help keep skin cool and dry
  • Sleeve can be machine washed for convenient maintenance

How Does the Sigvaris Adjustable Sleeve Work?

Venous conditions such as lymphoedema can occur when blood does not flow from your extremities as freely as it should. The Sigvaris Compression Sleeve applied graduated compression to your leg, which helps to encourage the upward flow of blood from your feet and legs.

What Colour Is The Sleeve?

This sleeve is supplied in a black colour which can be matched with other dark garments for more discreet wear.

What Makes This Wrap So Easy to Apply?

This wrap has lateral straps which allow for easy closure and adjustment, even by those with limited strength and mobility. The straps' built-in visual indicators also ensure the sleeve can be tightened to the ideal amount of compression every time.

How Durable Is This Wrap?

The metal clasps of this wrap improve its durability as they are less likely to become damaged or worn compared to Velcro closures. The wrap can also be machine washed for long lasting, hygienic use.

Can This Wrap Be Worn On Broken Skin?

When covering broken or sensitive skin, it's vital that the area is able to breathe to facilitate a healthy recovery. The lightweight mesh material of this sleeve is designed specifically for this purpose, which is why it is such a fantastic choice for treating active or recurring ulceration of the calf.

How Much Compression Does This Wrap Provide?

The straps on this compression sleeve can be adjusted to achieve between 20 - 30 mmHg and 40 - 50  mmHg. The built-in visual indicators can help users accurately tighten their straps to the correct level of compression.

How Much Compression Do I Need?

Generally, 20 - 30 mmHg is considered a moderate level of compression and is suitable for treating mild to moderate conditions, while compression levels over 30 - 40 mmHg are suitable for treating more severe conditions. However, if you are unsure of which level of compression you require for you condition, we strongly suggest referring to a medical professional.

Can I Wash This Sleeve?

To wash your sleeve, fasten all the hooks then place it in a mesh laundry bag before machine washing on a gentle cycle (with a mild detergent). It can then be tumble dried on a low setting, but air drying is recommended to maintain the product's lifespan.

What Materials Is the Sleeve Made From?

(Not including the Basic Liners)

  • 61% Polyester
  • 30% Nylon
  • 8% Elastane
  • 1% Stainless Steel
  • Latex free
