Natural down jacket - Unisex -
The unisex Vertigo Diamond Duvet Ardesia jacket from Montura is a technical mid-weight jacket, offering the perfect combination of warmth and essential lightness for mountaineering, climbing, and the most demanding outdoor adventures.
At the heart of its insulation is a filling of 750 CUIN duck down, treated with the Nikwax Hydrophobic Down process. This insulation retains heat even when the down is wet and allows it to dry faster than untreated down. The jacket’s Thermo-Adaptive technology ensures a stable body temperature even in the coldest conditions. The outer fabric is made from ultra-light recycled nylon Pertex® Quantum Diamond Fuse with a ripstop construction. This technical fabric, whose unique diamond-shaped filaments make it extremely abrasion resistant, is also windproof and features a PFAS-free durable water repellent treatment, providing light protection against external moisture and rain.
The construction of this jacket is entirely focused on performance and ergonomics in alpine environments. Its athletic fit ensures a perfect fit to be worn as a mid-layer or outer layer. The ErgoFit construction improves freedom of movement while reducing bulk in key areas. For maximum functionality, the jacket features a double-slider central zip, zipped hand pockets, an inner pocket with a Velcro closure, and a pocket that doubles as a stuff sack for compressing the garment. The adjustable hood is helmet compatible, the hem is elasticated, and the elasticated cuffs with thumb loops ensure a secure fit and optimal heat retention during challenging traverses and ascents.

| Pertex® Quantum Diamond Fuse | Pertex® Diamond Fuse is made from yarns whose filaments resemble the shape of a diamond. Thanks to this structure, the filaments can be interlaced extremely tightly, resulting in an exceptionally robust and abrasion-resistant fabric. The material is stable and durable, while remaining lightweight, soft, and windproof. |
| Nikwax Hydrophobic Down™ | Providing excellent thermoregulation, the down dries three times faster, absorbs 90% less moisture, and retains its loft 60 times longer compared to untreated down. |
