SKY Gravity Vibram chalk bag boulder

The Gravity Vibram by SKY is a chalk bag for bouldering characterized by a technical design that aims for maximum stability and lightness during outdoor and indoor use. The heart of this model is the base made of Vibram® rubber, which, thanks to its exceptional grip and the right weight balance, prevents the bag from accidentally tipping over. The body is constructed from silver Tyvek, a high-density polyethylene technical material that is ultra-lightweight (only 71 g total) but incredibly resistant to tears, water, and chemical agents. Inside, SKY has implemented an exclusive torsion structure that protects the chalk: even if the bag falls, the powder remains trapped, minimizing spills. Practicality is enhanced by the semi-transparent fabric pocket, ideal for quickly locating small items and accessories, while maintenance is very simple as the rubber base can be brushed to restore grip and cleanliness. As with the Drop series, every seam is treated with a seamless process that eliminates chalk loss from needle holes. With a height of 25 cm and a wide opening, it offers comfortable and quick access. Please note that each individual piece is unique and different from the others, as the colors are assorted and randomly chosen to ensure you always receive an original product.
