Hello all. Have to agree with R.Boreal about the Kolibri saddle pros and cons. I have the 3D multi-slide and it has to be the most thought out harness I have worn. I have been an arborist for 31 years and have tried and owned many different types. I also climb buildings, bridges and towers for a living as a high rigger and am an intern facilitator in Md. While the Kolibri has a few shortcomings, overall it is far more comfortable and cheaper than the Treemotion. It is a sliding D setup which is very adjustable in length. I run my bridge rather close to my body. I also did away with their D ring and simply use 2 biners in its place. I prefer the Petzl Gecko and the DMM Boa because they are colored red and green and they both have a rather wide bottom which mates up very well to the 2" wide webbing used as bridge material. My saddle also came from American arborist and I just visited them to try out the suspenders made by Kolibri. Will follow up on thoughts about them after giving them some proper break-in climbing. As a side note: Dave at Amer.arborist is great to deal with and very well versed in all the gear he carries. I also own several variations of Newtribe saddles for students and find them to be quite comfortable for a wide range of body types. Before I owned the Kolibri I wore a CMM/Yates towerclimbers harness. Nice to count on your gear when you spend your day hanging on the side of a 1000 ft. microwave tower above the clouds. Thanks for letting me add in here. Love this site and the community. Climb safe.
