The SKYLOTEC Kollibri harness is also known as the EKN or Hummingbird and will be available soon from Treetools. The Kollibri is considered by many climbing arborists to be the most supportive, comfortable tree climbing harness on the market.
It's padded in all the right places: spine pressure points (it has a large back support strap), and firm thigh slings (the Kollibri has twice as much supporting material as the Petzl Sequoia harness). The model available from Treetools will have the larger 2 inch side D-rings.
