    A lightweight insulating technical garment for FAST&LIGHT activities in cold conditions, known for its excellent weight/insulation ratio and high compressibility. With its innovative asymmetric zipper design, it prevents discomfort even when worn for long hours. The short-sleeve design maximizes arm maneuverability and freedom. It features two chest pockets for easy access to gear. Its ¾ zipper reduces weight and facilitates harness use.

    The outer fabric offers excellent wind and rain resistance (PFC-Free), which, combined with the Sorona® bio-synthetic fill panels (80 gr/m2 in the chest and back, 60 gr/m2 in the neck and arms), ensures thermal protection and optimal breathability. Pair it with other W-Series garments (compatible zippers between layers) and discover the lightest and most functional way to tackle the mountains. Ideal as a mid-layer over the W-Series Merino Baselayer or as an insulating layer over the W-Series Stretch Pullover.

    "This garment, essential in any wardrobe, is a true tribute to functional minimalism. I have used it in all my activities, from trail running to mountaineering, climbing, skiing, and paragliding, and it has always proven to be compatible with each one of them. Its lightness and versatility make it an indispensable piece, adapting to any discipline without adding unnecessary weight. The half zipper with double sliders is one of its most practical features: it allows you to keep the neck protected, access inner pockets, or ventilate the chest according to the activity's needs. Additionally, the elastic chest pockets are perfect for carrying essential gear comfortably and securely. Its design, without a hood or sleeves, offers unmatched freedom of movement, ideal for intense activities. It is much more than a garment: it is a loyal companion that enhances every adventure, at any time of the year."

    We can say that this was the link, the garment with which everything began: we had each designed and produced a sample independently without speaking beforehand, and we realized that there was a FAST&LIGHT connection, a very similar way of understanding mountaineering.

    Technology
    STORMFLEECE™ PRO fabric uses patented technology from Singtex® to create a single-layer fabric (without membrane) made of almost 70% recycled products. It resists wind and rain while providing excellent thermal insulation, high breathability, durability, and a very soft feel. This fabric was created using a combination of techniques, and its innovative construction ensures that the fabric leverages the strength and flexibility of fibers while significantly reducing material consumption. Its densely woven structure minimizes fiber and yarn waste, resulting in a fabric with a tough exterior and soft interior feel.

    The OS2O FAST&LIGHT line powered by STORMFLEECE™ PRO allows for the development of lightweight, durable, technical single-layer products. Fabric developed under the BLUESIGN® System Partner program.
