For living in a variety of environments, conditions, and different climates, we have created three categories of waterproof jackets. All fabrics for these jackets have been tested for waterproofness according to Japanese standard JIS L 1092:2009. Jackets made of fabrics laminated with membrane will resist light rain and wet snow for a long time. The most technically-packed jackets - DSUP, PLANCK, WERYK, and SYCAMORE - offer a high level of waterproofness from 16,500 up to 21,000 mm H₂O and their seams are taped to keep all water out.
