The SEQUOIA® is a tree care seat harness for doubled-rope ascent techniques. The extra-wide, semi-rigid waistbelt and leg loops provide comfort for the arborist. The waistbelt is equipped with a FAST buckle for quick and easy fastening and unfastening without loss of adjustment, even while wearing gloves. The leg loops have FAST LT PLUS buckles. The gated attachment points allow the user to easily connect a ZILLON or MICROFLIP lanyard, or to install several attachment bridges and accessories directly on the bridge. The harness also makes it easy to carry and organize work tools, with multiple equipment loops and slots for attaching CARITOOL tool holders.
