Sigvaris (brand)

Sigvaris makes true graduated medical compression in every garment type and strength class, with consistent sizing charts that map to real limb measurements.

Not for: People who need a custom-made or flat-knit garment for lymphedema, which should come through a fitter rather than off the shelf.

JOBST Relief (line)

Graduated compression and multiple sizing options make this a practical choice when professionally fitted in a clinician-recommended compression strength.

Not for: People with significant arterial disease unless specifically cleared by their clinician.

Claude also picks JOBST for “widest everyday range”.

Which one fits you

widest everyday range

Jobst (brand)

Not for: Anyone who already knows another brand's sizing fits them better.

budget basics

Truform (brand)

Truform sells genuinely graduated, mmHg-labelled garments at the entry end of the market.

Not for: Daily long-term wearers who need fabric that holds compression over months of washing.

Check before you buy

Compression class. 8-15 and 15-20 mmHg are over-the-counter comfort levels; 20-30 and 30-40 mmHg are medical classes usually prescribed for varicose veins, edema, DVT history or lymphedema The wrong class either does nothing or is unsafe, and the class is the main way products in this category differ.
Graduated design. Pressure should be highest at the ankle or wrist and decrease toward the top Graduation is what moves fluid back toward the heart; uniform squeeze can trap fluid.
Sizing by measurement. Measure the ankle and calf (or wrist and upper arm) circumference in the morning, before swelling sets in, and match the brand's chart Shoe size or S/M/L guesses produce bands that dig in or garments that give no real pressure.
Arterial safety. Get medical clearance before wearing 20 mmHg or more if you have peripheral arterial disease, diabetes with neuropathy, or heart failure Compression can reduce blood flow in already-poor arteries.
Replacement interval. Replace daily-wear garments roughly every 3 to 6 months Elastic loses pressure with wear and washing, even if the garment still looks fine.

Questions

Socks, stockings or tights?

Knee-highs suit most leg swelling and travel; thigh-highs or tights are needed when veins or swelling extend above the knee.

Do I need a prescription?

Not to buy most garments, but 20 mmHg and above should be chosen with a clinician, and some insurers require one for coverage.
