The Wilsa overbag is the equipment of choice for the modern explorer. It provides optimum protection against driving rain, silent snow or starry bivouacs. That’s why this accessory is our bestseller.
The sursac is a high-performance barrier against the elements. Its advanced technology wraps you in a waterproof, breathable shell, significantly increasing your sleeping bag’s thermal insulation while preserving its breathability so you’re protected. Stay dry and warm, whether you’re on a windy summit or in a damp valley.
With a featherweight of just 500g and generous dimensions: 230x80cm, the sursac won’t weigh down your shoulders. Son ingenuity lies in its ability to offer maximum protection without overloading your pack. Son 1-liter stuff bag allows it to be compacted to the extreme, making it almost invisible in your equipment until the need arises.
Thanks to the modulas concept, the overbag integrates perfectly with your hiking gear. Combinable and adaptable, it reinforces your sleeping gear without making itself felt, hugging the contours of your sleeping bag with disconcerting ease.
Son’s ease of use and versatility make it an obvious choice for the contemplative walker, the daring climber or the touring cyclist.
