Why Plus Size Compression Can't Just Be "Bigger"
Size-Matched Knitting
Each circumference band runs on the correct cylinder needle count with high-recovery elastane plating; every size is confirmed with a pre-production sample before bulk.
Per-Size Pressure Testing
Graduated compression re-calibrated for every size band and verified on Swisslastic MST MK V; test report available per size on request.
Proportional Widening
Foot, ankle and calf scale together. A sock that only widens at the calf fails at the instep—ours doesn't.
Wide Comfort-Top Cuff, No Dig-In
Widened rib cuff distributes top-band pressure; stay-up via anti-slip yarn (silicone band reserved as medical-grade option).
We Don't Just Offer Plus Sizes—We Build Your Size System
The biggest hidden cost in plus size compression is sizing chaos: no universal standard, every brand's chart different, returns driven by mis-fits. We develop a size chart for your market before we knit a single pair.
What we define together:
- Foot length ranges
- Ankle circumference
- Calf circumference bands
- Calf height (knee-high length: petite / regular / tall)
- Thigh circumference (for thigh-high styles)
- US / EU / UK size chart adaptation
- Size naming aligned to your market (2XL–6XL or your own system)
- Packaging size guide & product insert artwork support

Quality Control Built Around Pressure Accuracy
In extended sizes, quality means one thing above all: the pressure printed on the label is the pressure on the leg. Our four-stage QC process is built around that promise.
Yarn & Material Inspection
Every elastane and yarn batch is inspected on arrival for elasticity and recovery consistency—the foundation of stable compression at larger circumferences.
In-Line Knitting Checks
During production, flat-width and circumference are checked against each size band's spec sheet, so a 3XL is knitted as a 3XL—not labeled as one.
Per-Size Pressure Testing
Swisslastic MST MK V — medical-grade compression testing in-house
Each size band is tested on our Swisslastic MST MK V to verify the graduated pressure curve holds from ankle to calf. Test reports available per size on request.
Final AQL 2.5 Inspection
Pre-shipment random inspection to AQL 2.5 covers sizing, stitching, cuff integrity and packaging before your order leaves the factory.
From multi-gauge knitting machines to in-house pressure testing—see the equipment behind every extended size we make.
