Loro Piana Zermatt Jacket - Review
Loro Piana · $4,200-$4,800 retail
Reviewed February 2026 · The Fashion Desk
The verdict
The Zermatt is the most quietly competent field jacket on the market. After twelve months of daily wear in three climates, the cashmere-blend Storm System fabric has resisted every condition we have tested it in, the cut works under tailoring as easily as over a knit, and the construction has shown no fatigue. The $4,800 price is high; the value is genuine.
What works
- Storm System fabric - unmatched water resistance for a wool blend
- Removable cashmere lining adapts the jacket across seasons
- Cut works equally well over knitwear and under a sport coat
- Construction details (bound seams, horn buttons) are exemplary
What doesn't
- Pocket layout is restrained even by minimalist standards
- Sizing runs slightly slim through the chest for athletic builds
The Zermatt has become the canonical Loro Piana outerwear piece - the jacket that demonstrates, in a single garment, what the maison's Storm System technology, cashmere blends, and construction standards actually deliver. After a year wearing the rust-coloured Storm System Zermatt across London, Milan, and the American Northeast, this is our considered editorial review.
The Storm System fabric
Storm System is Loro Piana's proprietary three-layer treatment that bonds a microporous membrane between an outer cashmere-wool blend and an inner lining. The result is a wool fabric that resists rain to a degree that no untreated wool achieves while retaining the hand and drape of a soft cashmere blend. We have worn the Zermatt in sustained London rain (45 minutes plus), American Northeast snow, and Milanese drizzle - in each case the fabric has remained dry to the inner lining. The treatment does not affect breathability noticeably.
The cut
The Zermatt is cut as a relaxed-fit field coat rather than a slim modern jacket. The shoulders sit naturally without over-padding; the body is roomy enough to layer over a chunky cashmere knit; the sleeves taper without restricting movement. Critically, the cut also works under a sport coat or unstructured suit, which is unusual for a field jacket of this length (sits two inches below the hip). For most builds, true-to-size is correct; athletic builds may want to size up one.
Construction details
Bound seams throughout. Horn buttons (genuine, not corozo). A removable cashmere lining attached by a deliberately discreet zipper system. Pockets with leather-trimmed flaps. The interior is lined in cashmere where it sits against the body and in cotton where it sits against outerwear-weight knits. Every detail communicates the Loro Piana standard: nothing performative, everything correct.
Twelve months of wear
The fabric has held its colour under regular UV exposure (the rust shade has not visibly faded). The buttons remain firmly attached. The lining has seen no shedding. The water resistance has not diminished noticeably. The only criticism after a year is that the cashmere outer has developed a very slight pile around the cuffs from contact with watch bracelets - not a flaw, but a sign of use.
Who it's for
The buyer seeking one outerwear piece that will work across weather, settings, and seasons for a decade. The Zermatt is also the right choice for buyers who want quiet luxury in its purest form - the jacket has no visible logo and is recognised only by other Loro Piana owners.
Who it's not for
Buyers who prioritise visible brand recognition (a Moncler down or Canada Goose parka delivers that) or buyers in genuine technical contexts (an Arc'teryx Beta AR is more appropriate for serious mountaineering). The Zermatt is a quiet field coat, not an alpine shell.
