Mobilis by Sigvaris: Where It Fits in the Sigvaris Lineup

Last reviewed: September 18, 2026 · Compression Socks Canada Team

The Sigvaris portfolio is one of the most extensive in medical compression. Within that portfolio, Mobilis by Sigvaris occupies a specific role that often gets overlooked by everyday shoppers because it does not compete in the everyday-stocking aisle. Mobilis sits in the flat-knit, condition-targeted side of the catalogue — the products that come into play when off-the-shelf round-knit hosiery is no longer the right answer, when limb shape requires precise containment, or when a clinical care team has specified a particular knit construction and pressure profile. This article walks through where Mobilis by Sigvaris fits within the broader Sigvaris lineup, which conditions it serves, what it looks like in practice, and how Canadian patients typically access it. It is general educational content and not a substitute for advice from a certified lymphedema therapist or physician.

A quick map of the Sigvaris portfolio

Sigvaris produces compression products across several lines. A useful way to think of the catalogue:

• Everyday round-knit hosiery. Cotton, microfibre, sheer, and athletic options across 15-20, 20-30, and 30-40 mmHg.
• Specialty round-knit lines. Sea-island cotton, linen, soft silhouette, and similar.
• Athletic and active lines. Designed for sport and active everyday use.
• Maternity, men's, and condition-targeted hosiery.
• Flat-knit and custom-fit garments. Where Mobilis lives.
• Accessories and donning aids.

What flat-knit construction means in practice

Compression garments are knit on either circular machines (round-knit) or flat machines (flat-knit). The difference is technical but practically important:

• Round-knit fabric is seamless, thinner, and well-suited to limbs that are relatively symmetrical and within standard size ranges.
• Flat-knit fabric is heavier, has a seam, and provides stronger, more consistent containment across irregular limb shapes.

Flat-knit is the go-to construction when:

• The limb has significant shape irregularity (common in stage 2 and 3 lymphedema).
• The limb has lost firmness and requires firmer containment.
• The clinical situation requires more aggressive volume reduction.
• Round-knit garments fail to deliver consistent pressure because the limb does not match standard design assumptions.

Mobilis by Sigvaris focuses on flat-knit products. The category exists because round-knit cannot serve every patient well.

Conditions Mobilis is designed to serve

The Mobilis line is positioned for several specific clinical contexts:

• Lymphedema, particularly stage 2 and 3 of both upper and lower limbs.
• Lipedema, where the disproportionate fat tissue produces leg shapes that round-knit garments do not handle well.
• Severe chronic edema that requires firmer containment than round-knit can provide.
• Post-traumatic and post-surgical limb conditions where standard hosiery is inadequate.
• Patients with significantly irregular limb shape for any reason.

For most everyday venous indications — varicose veins, post-sclerotherapy support, work-day swelling, travel — round-knit Sigvaris hosiery is the right starting point, not Mobilis. The line comes into play when a clinical assessment identifies a specific need for flat-knit construction.

How patients access Mobilis

Flat-knit compression is typically prescribed and fitted by a certified lymphedema therapist (CLT) or trained compression fitter. The process usually includes:

1. Clinical assessment of the limb and the underlying condition.
2. Detailed measurement, often more extensive than for round-knit products.
3. Selection of pressure class, knit type, and product configuration.
4. For custom flat-knit, a manufacturing process based on the specific measurements.
5. Fitting and follow-up to confirm the garment performs as intended.

Off-the-shelf flat-knit options exist for some configurations; custom flat-knit covers the rest. The choice depends on the limb's specific shape and the clinical situation.

Pressure classes typical in Mobilis use

Flat-knit garments are often used at higher pressure classes than round-knit hosiery:

• 20-30 mmHg for many upper-limb lymphedema cases and milder lower-limb cases.
• 30-40 mmHg for moderate to severe lower-limb lymphedema and lipedema.
• 40-50 mmHg and above for severe lymphedema, typically in custom-fit products.

Pressure decisions for diagnosed conditions belong with the certified lymphedema therapist and treating physician. See our lymphedema stages article for the broader framework.

Donning flat-knit garments

Flat-knit garments are generally harder to don than round-knit hosiery because of the heavier, less stretchy fabric. Donning aids become particularly valuable:

• The Doff n' Donner is a common choice.
• Frame-style butlers help patients who cannot reach their feet easily.
• Silk under-liners reduce friction during donning.
• Two-piece systems split the garment into components that can be donned separately.

See our donning aids article.

Daytime and nighttime garments

Patients managing lymphedema often use different garments by time of day:

• Daytime garments are the firmer flat-knit products that deliver consistent pressure during upright activity.
• Nighttime garments are softer, lower-pressure quilted or foam-based products that maintain limb shape overnight when the daytime garment is off.

Mobilis-style flat-knit covers the daytime category. Specific nighttime products exist in parallel.

How Mobilis fits alongside the rest of the lymphedema care plan

Compression is one component of comprehensive lymphedema management. The broader care plan typically includes:

• Decongestive therapy with a certified lymphedema therapist.
• Manual lymphatic drainage when indicated.
• Short-stretch bandaging during intensive treatment phases.
• Skin care to reduce cellulitis risk.
• Exercise tailored to the limb and the patient's condition.
• Education on warning signs, garment care, and self-management.

The Canadian Lymphedema Framework publishes patient resources and a directory of certified therapists across Canada.

What Mobilis is not

A few clarifications help set expectations:

• Mobilis is not a replacement for everyday round-knit hosiery for typical venous indications.
• It is not an off-the-shelf product line for general shoppers.
• It is not necessarily more expensive than other flat-knit options — but the category as a whole carries a higher price than round-knit hosiery.
• It does not replace decongestive therapy. It supports the therapy plan.

Care and replacement

Flat-knit garments typically need:

• Gentle washing according to the manufacturer's instructions, often hand wash or machine gentle.
• Air drying, never tumble drying on heat.
• No fabric softener.
• Rotation of two garments so each can recover between wears.
• Replacement every three to six months for daily wear.

See our laundry guide article for the underlying care principles.

When to ask about Mobilis specifically

Patients and caregivers often ask about Mobilis when:

• Round-knit hosiery has not been delivering adequate symptom control.
• Limb shape has evolved beyond what off-the-shelf accommodates.
• A certified lymphedema therapist has identified the need for flat-knit.
• The clinical situation has progressed and a stronger containment is required.
• An off-the-shelf flat-knit has not fit well and custom-fit is being considered.

Putting it together

Mobilis by Sigvaris occupies a specific, important role in the Sigvaris portfolio: the flat-knit, condition-targeted side of the catalogue where round-knit hosiery is not adequate. The line serves patients with lymphedema, lipedema, severe chronic edema, and irregular limb shapes — conditions where containment, consistent pressure profiles, and accommodation of unusual limb geometry matter more than the cosmetic thinness of round-knit fabric. For most everyday shoppers without a specific clinical need, Mobilis is not the right starting point; round-knit Sigvaris hosiery is. For patients whose clinical picture has moved beyond what round-knit can serve, Mobilis represents an important option that should be selected and fitted in coordination with a certified lymphedema therapist or trained compression fitter. With the right product correctly fitted and the right broader care plan in place, daily compression — whether round-knit or flat-knit — delivers the consistent therapeutic effect that conditions like lymphedema rely on.
