Why Medical-Grade Graduated Compression in Cotton for Venous Health?

Compression therapy for chronic venous insufficiency, varicose veins, and lower limb oedema is one of the most evidence-supported interventions in phlebology and vascular medicine, and the mechanism through which it works is specific to the graduated pressure gradient that distinguishes medical compression from simple elastic socks or support hosiery. The 20-30 mmHg pressure range of the Sigvaris Essential Cotton represents the Class 2 moderate compression tier in the European classification framework and corresponds to the medium compression tier commonly used in Canadian and North American clinical practice — a pressure level prescribed or recommended for conditions where the venous system requires meaningful external support to maintain adequate venous return but where the patient can typically tolerate and don the garment independently. The graduated nature of the compression — calibrated to provide maximum pressure at the ankle and progressively decreasing pressure up the leg — creates a pressure gradient that mechanically supports the one-way valve function of the perforating veins, reducing venous reflux and the hydrostatic pressure that drives fluid out of the venous capillaries into the surrounding tissue.

At 20-30 mmHg, the Sigvaris Essential Cotton addresses a clinically meaningful step up from the 15-20 mmHg preventive range. While 15-20 mmHg hosiery is appropriate for fatigue prevention, mild swelling from prolonged standing or sitting, and prophylactic use during air travel, 20-30 mmHg is the compression level typically prescribed by physicians for patients with confirmed moderate chronic venous insufficiency (CVI), documented varicose veins producing symptoms, oedema requiring ongoing management, post-sclerotherapy and post-surgical vein treatment support, and occupational venous hypertension in standing workers. In patients with these conditions, the additional pressure delivered by the 20-30 mmHg garment is not merely incrementally better than a lower compression level — it is clinically necessary to achieve the haemodynamic effect required to reduce symptoms and slow the progression of the underlying venous disease. This is why the 20-30 mmHg range is the most commonly prescribed medical compression level in clinical venous management practice.

The cotton-rich construction of the Sigvaris Essential Cotton line reflects a clinically driven fibre selection decision. Compression stockings are worn for extended periods — often eight to twelve hours per day, seven days per week in active venous disease management — and the cumulative skin contact time makes fibre selection a material determinant of skin tolerance, wearability, and compliance. Synthetic microfiber compression stockings offer excellent durability and wash performance but can accumulate moisture at the skin surface in warm conditions, generating the maceration, skin barrier disruption, and contact dermatitis that cause patients to discontinue therapy before therapeutic benefit is achieved. Cotton fibre absorbs moisture vapour naturally, wicking perspiration away from the skin surface and maintaining a drier, lower-humidity microenvironment at the skin-stocking interface that is significantly more comfortable for extended wear, particularly for patients with sensitive skin, diabetes, or conditions that increase skin vulnerability to moisture-related breakdown.

The open-toe design of these stockings provides two clinical advantages that make it the appropriate specification for many prescription and retail compression garment contexts. The absence of a toe section eliminates the most common source of fit-related discomfort and toe injury in closed-toe compression stockings — the toe seam and toe box that, when imprecisely fitted to individual toe length and spacing, creates pressure points, blisters, and nail trauma in patients wearing the stockings for extended periods. The open toe also allows direct visual inspection of the toes and toenails during wear without removing the stocking, which is clinically relevant for diabetic patients, patients with peripheral vascular disease, and wound care programs where regular toe and foot skin surveillance is part of the care protocol. For these patient populations, the open-toe specification is not merely a comfort preference but a clinical monitoring requirement.

Benefits

• Reduces leg swelling by externally supporting venous return against the hydrostatic pressure gradient in the lower limb
• Manages varicose vein symptoms including aching, heaviness, and visible vein prominence through graduated compression support
• Supports post-sclerotherapy vein closure by maintaining mechanical compression during the post-treatment healing period
• Reduces occupational oedema in individuals who stand or sit for extended periods during work shifts
• Cotton-rich fabric reduces the skin irritation, maceration, and contact dermatitis risk associated with all-synthetic compression stockings
• Open-toe design supports diabetes and vascular disease toe skin surveillance during daily wear without stocking removal
• Medical-grade Sigvaris construction maintains compression accuracy wash after wash — Sigvaris guarantees compression performance over the garment lifetime
• Comfortable daily wear compliance support — comfortable stockings worn consistently deliver far better therapeutic outcomes than uncomfortable stockings worn intermittently

Clinical and Wear Applications

✓ Chronic venous insufficiency (CVI) management requiring ongoing graduated compression support for venous return ✓ Varicose vein symptom management for aching, heaviness, oedema, and skin changes associated with superficial venous reflux ✓ Post-sclerotherapy compression following foam or liquid sclerotherapy for varicose or reticular veins ✓ Post-surgical venous intervention support following endovenous laser ablation, radiofrequency ablation, or surgical stripping ✓ Moderate lower limb oedema management in non-cardiac, non-lymphatic oedema appropriate for 20-30 mmHg compression ✓ Occupational venous hypertension in standing workers including retail, healthcare, hospitality, and hair salon staff ✓ Deep vein thrombosis (DVT) secondary prevention as part of a post-thrombotic syndrome management program ✓ Diabetic patients requiring breathable moisture-managing compression with open-toe design for foot surveillance ✓ Patients with sensitive skin or contact dermatitis from synthetic compression fibres requiring cotton alternative ✓ Post-partum venous recovery for women with pregnancy-acquired varicosities or oedema ✓ Compression stocking program compliance support for patients who have previously discontinued synthetic compression due to skin discomfort ✓ Travel compression during long-haul flights or extended ground transport for patients with moderate venous disease

Usage & Application

Donning the Sigvaris Essential Cotton Open-Toe Stocking Turn the stocking inside out to the heel before donning — this is the standard method for applying compression stockings correctly. Hold the stocking with both hands at the heel pocket and pull the foot section right-side-out over the hand, leaving the leg section inverted. Slip the foot into the stocking foot section, aligning the heel pocket precisely with the heel of the foot. Once the foot is correctly positioned with the heel pocket seated, gradually roll the stocking leg section up over the calf using both hands simultaneously, working in small increments rather than one single upward pull. Do not pull the stocking by the top band alone — distribute the pulling effort throughout the roll-up motion to avoid stressing the cuff and the upper compression zone. Ensure the stocking lies smooth and wrinkle-free on the leg — no folds, which concentrate pressure at fold points and can cause skin indentation.
