Wildstrubel Merino Jumper - F: Revario's versatile layer, under the O!radar
A merino and nylon jumper, made in Switzerland, built for outings where the weather changes without warning. Hooded, with two thumbholes, it is assembled in Marly, in the canton of Fribourg.
What it is
Revario’s Wildstrubel Merino Jumper - F is designed, according to the brand, for outings where the temperature keeps changing through the day. This hooded top, fitted with two thumbholes, sits in the technical layering category: not quite an everyday jumper, not quite a heavy technical jacket, but something in between.
The brand offers it in two colourways, grey-blue and sky-blue, across a size range from XS to XL.
Revario is a Swiss brand, with garment assembly carried out in Marly, in the canton of Fribourg. The brand highlights its bond with its community, whom it calls the “Revariors”, along with a certain pride in a product partly made on Swiss soil.
Why it exists
The problem Revario is trying to solve will sound familiar to anyone into hiking, mountain sports or simply spending time outdoors in Switzerland: temperature never stays stable for long. You set off freezing, sweat on the climb, then cool down fast the moment you stop. A single layer that does it all doesn’t really exist — but Revario positions this jumper as an answer to that variability.
According to the brand, this jumper regulates body temperature while offering excellent breathability, great freedom of movement and very fast drying. In other words: stay active without overheating, and don’t end up carrying a soaked garment after the effort. The brand goes further, describing this jumper as the ideal versatile layer for outings where temperatures keep shifting — a mid-layer role, sitting between a technical base layer and a waterproof shell.
What matters
The fabric composition sets the tone for this product. It’s a blend of merino wool, nylon and elastane. Merino wool brings temperature regulation and the natural feel often sought outdoors; nylon adds strength and abrasion resistance; elastane provides the stretch needed for freedom of movement. So this isn’t a hundred per cent wool jumper — a choice that directly shapes how the garment behaves in use, particularly when it comes to drying and durability.
The weight, for size M, comes in at 150 grams. That’s a useful figure for anyone thinking about pack volume and overall load: a jumper in this weight range is easy to carry as a backup layer, without significantly adding to your kit.
Design details — a hood and two thumbholes — genuinely change how the garment performs outdoors. The hood lets you cover your head without having to dig out a beanie or another piece; the thumbholes shield the back of the hand from wind or cold, a detail that’s appreciated during stops or at the start and end of an outing, when hands are usually the first to suffer.
The fit, described as regular, points to a garment designed for versatile use rather than a slim or oversized cut. That should, in principle, leave room to layer something underneath or over the top without excessive constraint.
The manufacturing journey is worth noting. Assembly takes place in Switzerland, in Marly, while the fabric is knitted and dyed by Pontetorto SPA in Prato, Italy — an area well known for its textile expertise. The logo, meanwhile, comes from a supplier based in Saint-Étienne, France. This multi-step journey places the product within a European production chain, with final assembly in Switzerland.
The washing temperature, set at 40°C, is a practical care guideline: neither a strict cold wash nor an aggressive hot cycle, which lines up with what you’d generally expect from a wool-blend garment.
Day to day
Day to day, this jumper works as a mid-layer or a standalone piece depending on the weather, with its hood ready to cover your head against sudden wind or a cold snap. The thumbholes slip over your hands during breaks or on descents, without needing to reach for gloves.
On the care side, the jumper is washed at 40°C, a moderate temperature compatible with the merino wool content.
According to the brand, the garment itself dries very quickly once worn or washed, which could simplify logistics on multi-day trips where you sometimes need to rewash and reuse the same piece in short order.

What the brand says
Revario states that the Wildstrubel jumper regulates body temperature while offering excellent breathability, great freedom of movement and very fast drying. These are four distinct claims, made by the brand itself, touching on thermal comfort, ease of movement and practical upkeep.
The brand also describes this jumper as the ideal versatile layer for outings where temperatures keep changing. This framing clearly positions the product as a mid-layer piece, designed for adaptability rather than a single specialised use.
Why it caught our eye
We picked this one out for its genuine Swiss roots, with assembly in Marly and real attention to detail — hood, thumbholes — designed for outings where the weather doesn't keep its promises. We also appreciate Revario's transparency about the manufacturing journey, from Italy to France, through to final assembly in Switzerland.
Exactly the kind of brand we’d love to come across on O!deal one day.
