Pertex Quantum
Ultralight ripstop nylon developed by Pertex (UK). High tear strength relative to its weight, with a calendared face that sheds light precipitation. We use it in the Helix Puffer for warmth-without-bulk and as a windproof outer layer.
Every Clothixpack garment is specified, sampled, field-tested, documented, and checked through a controlled product workflow. Every fabric on this page is named by mill, denier, weight, and treatment. If a fabric isn't listed here, we don't ship a garment made from it.
Each garment moves through six stages. The whole cycle, from brief to a drop landing in your cart, takes 12 to 16 weeks. The result is a product record that names the fabric, construction, fit notes, and pre-dispatch checks.
Climate range. Cargo demand. Range of motion. What failure mode must it survive? Every piece starts with a one-page brief that we publish on the product page when it ships.
We pick the fabric to fit the brief, not the other way around. Mills are named, samples are tested for hydrostatic head, MVTR, abrasion resistance, and lightfastness. Lab reports archived.
Pattern-making follows the technical brief. First samples are wear-tested on real commutes, rain or shine, for at least two weeks before any adjustment.
Articulation, gusset placement, pocket geometry, zipper grade. Usually 2 to 4 sample rounds. The piece is signed off only when it passes the brief — not when the calendar runs out.
Small, costed runs. Each finished piece is inspected, serialized, and assigned a registration code. The serial is sewn into the inner seam before the garment is folded.
Tracked shipping options are shown before payment where available. The serial registers to your order at checkout, opening product traceability. Every shipment leaves with a traceable product record and a pre-dispatch check.
Ultralight ripstop nylon developed by Pertex (UK). High tear strength relative to its weight, with a calendared face that sheds light precipitation. We use it in the Helix Puffer for warmth-without-bulk and as a windproof outer layer.
Three-layer construction: face fabric, hydrophilic membrane, knit backer. Bonded together rather than stitched, then fully taped at every seam. Hydrostatic head rated for sustained light-to-medium rain.
500-denier Cordura nylon by INVISTA. Built for abrasion resistance — designed originally for military and industrial workwear. The brushed weave shrugs off scrapes from bag straps, brick walls, and bike frames.
Three-layer softshell with a fleece backing. Stretch warp for movement, knit face for abrasion, brushed interior for warmth. Wind-resistant; rain-resistant in light precipitation; not waterproof in sustained downpour.
Tightly woven nylon-elastane blend with 4-way stretch. Used on technical pants where range of motion matters — long stride, deep squat, full reach. Articulated knees and gusseted crotch pre-shape the garment for movement.
Heavyweight French terry loopback knit. 500 grams per square meter is double the average hoodie. The result is a piece with structure — it hangs straight off the shoulder rather than collapsing.
Recycled polyester fill with hollow-core fibers. Comparable warmth-to-weight as 700-fill down, with better performance when wet and no animal sourcing. Used in the Helix Puffer as panel fill.
Hardware is where mid-tier brands cut cost and gear nerds notice immediately. We don't.

Pertex, Cordura, Polartec, Schoeller, INVISTA. If a mill stands behind their fabric with a brand, we'd rather pay for the certainty than save 8% on a "comparable" knockoff. The brand of the mill is the audit trail.
Hydrostatic head, MVTR, abrasion resistance, lightfastness. We test, archive, and publish the numbers. If you ask for the report, we send it.
Every water-repellent treatment we use is C0 / fluorine-free. PFAS regulation is tightening across the EU and California — we are ahead of the curve, not catching up.
30%, 50%, 60% — whatever the recycled content actually is, that is what the spec sheet says. "Made with recycled materials" is not a number; we don't write it.
Some fabrics are knit or woven by specialist mills — Pertex in the UK, Cordura in the US, Schoeller in Switzerland, organic cotton in Portugal. Every piece is then specified, field-tested, and documented through the Clothixpack product record. We publish both ends of the chain.
Clothixpack is a Canadian-registered brand with an international production and fulfillment workflow. Pattern-making, sampling, finishing, and product traceability are managed through one documented standard rather than a public retail studio.
No. Clothixpack does not mill or weave its own fabrics. We source named technical fabrics from specialist mills: Pertex (UK), INVISTA / Cordura (US), Schoeller (Switzerland), and organic cotton from GOTS-certified mills in Portugal. The fabrics are then specified, field-tested, and documented through the product record.
Some are, some are not — we are explicit about which. The Strata Shell (CXP-J014) is built from a 3-layer bonded nylon with fully taped seams and a 10,000 mm hydrostatic head rating; it is rain-resistant for sustained light-to-medium rainfall. The Vector Mid is a softshell — wind-resistant and light-rain-resistant but not waterproof. Each product page states the exact rating.
DWR (durable water repellent) is the coating that makes water bead off a fabric's surface. Historically, DWR coatings used PFAS — "forever chemicals" that don't break down in the environment. Clothixpack uses only C0 / fluorine-free DWR, which performs comparably without the persistent environmental impact. This is required by upcoming EU regulation and California law, and we have implemented it across the catalog.
A full drop cycle — from initial brief to garments shipping to customers — takes 12 to 16 weeks. The longest single phase is sample iteration, which can run 2 to 4 rounds before sign-off.
The atelier is not open to walk-in visits, but we host members-only studio days twice a year (typically in March and October). Sign up to the newsletter to be notified.
