THOM KROM M SJ 703 Sweat Jacket - Black Dual-Shell Cotton Elastane Worked Knit Men's German

Two Shells. One Jacket. Stretch Where It Matters.

The THOM KROM M SJ 703 is a worked knit sweat jacket built with two distinct shell fabrics: a 100% cotton shell for the primary panels, and a 97% cotton, 3% elastane shell for the panels where freedom of movement is the priority. A 100% cotton rib finishes the cuffs, hem, and collar. Three fabrics, each placed with precision. The result is a jacket that holds its structure where structure is needed, and gives where movement demands it — without compromising the visual consistency of a single-colour, no-logo worked knit construction. German design. Turkish manufacture.

Why This Jacket Is Different

• Dual-shell construction: Two shell fabrics in one jacket — 100% cotton for structure and body, 97% cotton / 3% elastane for targeted stretch in high-movement panels
• Targeted elastane placement: The 3% elastane is placed only in the panels that require it; the primary shell remains pure cotton for breathability, drape, and natural hand-feel
• 100% Cotton rib: Pure cotton at cuffs, hem, and collar — consistent natural feel at every contact point
• Worked / gewirkt construction: Loop-built fabric throughout — inherent stretch in the knit structure itself, amplified by the elastane shell where additional give is placed
• German design: THOM KROM construction intelligence — material decisions made for function, not cost reduction
• Unlike the M SJ 706 single-fabric jacket and the M SJ 705 lined jacket, the M SJ 703 is defined by its dual-shell panel strategy — a different construction logic for a different movement profile
• No logos: The construction and knit texture are the only visible identifiers
• Investment quality: Cotton-dominant construction with precise elastane placement — the stretch recovers, the cotton breathes, the rib holds

The Moment You Put It On

The cotton panels sit with the natural weight and drape of a premium worked knit. But when you raise your arms, reach forward, or move through a full range of motion, the elastane panels are there — not as a whole-jacket stretch, but as a precise give in the panels where the body needs room. The cotton rib sits clean at the wrist. The jacket moves with you without losing its shape when you're still.

This is the difference between a jacket built for wearing and one built for looking at. The M SJ 703 is both.

The Art of Dual-Shell Panel Construction

Most knit jackets use a single fabric throughout — either with or without elastane content. THOM KROM's dual-shell approach in the M SJ 703 treats the jacket as a panel-by-panel construction problem: which areas of the garment require structural integrity and natural cotton drape, and which require elastane-assisted stretch for freedom of movement? The 100% cotton shell handles the body panels that define the jacket's silhouette. The 97% cotton, 3% elastane shell handles the panels that flex when you move — typically the under-arm gussets, side panels, or back yoke, depending on the specific construction. At 3% elastane content, the stretch is functional without being visible — the fabric returns to its original dimensions after extension, and at this low percentage, it does not change the visual character or hand-feel of the cotton-dominant blend. The rib in 100% pure cotton maintains contact consistency at cuffs, hem, and collar. The M SJ 703 is the most technically considered jacket in the THOM KROM sweat jacket range.

How to Wear It

• As outer layer for active days: The dual-shell construction handles full range of motion without restriction — the jacket for days that involve movement, not just appearance
• Over the M S 197 sweatshirt: The cotton-dominant shell layers cleanly over the cotton sweatshirt; the elastane panels provide space for the additional layer beneath
• Under the M J 94 woven jacket: On cooler days — the M SJ 703 as a mid-layer, its knit stretch allowing the woven outer jacket to sit correctly without pulling
• With the M P 52 cotton trouser: A cotton-dominant look throughout; the dual-shell jacket brings construction intelligence to a material-consistent outfit

Care Instructions

• Machine wash cold, gentle cycle — inside out to protect knit surface texture and colour depth
• Do not tumble dry — lay flat to dry to maintain knit structure and prevent shoulder stretching; elastane panels benefit from flat drying to preserve recovery
• Do not bleach
• Low steam iron if needed — press from inside with a cloth barrier; avoid direct heat on elastane-blend panels
• Do not dry clean
• Store folded to prevent knit from stretching at shoulder seams over time
