The Buckingham AgilityTM saddle was designed in conjunction with Jamie Chambrelli, and the team at ArborMaster® Training Inc. Jamie is a lead instructor with ArborMaster®, Connecticut Licensed Arborist and production tree climber.

During development, Buckingham looked at feedback around the industry including proper fit, adjustment slippage, mobility of suspension systems, proper support at legs and back, lower hardware options and other attachment options throughout the suspension, and a plethora of other issues with saddles around the industry. The handmade in the USA Agility saddle was designed and built for “Work” with a focus on comfort, durability, mobility, and functionality.

Onyx Harness by New Tribe

Size 1
Size 2

The Onyx is a compact harness that provides support by improving the construction and design of the harness so the weight is distributed more evenly, thanks to the unique webbing pattern on the leg loops. The hang point on the Onyx is fully adjustable, with adjustment on the waist to rigging plates, rigging plates to leg loops, and from the back of the harness to the leg loops. The harness provides comfort without added bulk.

WesSpur stocks the Onyx with rigging plates and rope bridge, and the harness is also available with a webbing bridge. Conversion kits are available to convert the harness between the two.

Click here for Onyx with webbing bridge or conversion kits.

Onyx harness sizing: Size 1 (waist 26” to 37”), Size 2 (waist 35” to 46”).

The Onyx weighs under 5 pounds and is designed for professional use.

New Tribe Tengu Tree Harness

Tengu Harness by New Tribe


This “ultra-light” Harness is designed to be light and comfortable without sacrificing safety. The belt pad and leg pads on the Tengu are work-Harness shape and provide great support without restricting movement. The side D rings on the belt and the sliding D ring on the leg strap bridge are “soft” Ds that trim the weight, yet retain the strength of the Harness. Harness includes three soft gear loops, one on each side and one at the back, a carabiner loop behind each side gear loop, soft side Ds, two gaps on the belt webbing that can carry additional carabiners.

The leg straps have quick-release buckles, two accessory loops, one on each leg strap, (these little loops keep whatever you put there within easy reach.) These straps are now adjustable to accommodate a wide range of users. The soft floating D on the leg strap bridge glides smoothly when you shift from one side to the other. If you place the apex of your Delta Screw Link into the floating D it grabs the Delta tighter to prevent it from rotating as you climb.

Timber 3D Harness by Singing Rock

Size 1 - M/LG
Size 2 - XL
Replacement Bridge

The Timber 3D Harness is a very comfortable, lightweight, and well-padded tree climbing harness. This harness has the features you expect from a modern tree harness streamlined to keep the weight and price down. The padding on the Timber is very well designed for comfort without bulk. Replaceable bridge with sliding ring makes positioning easy. Leg loops run through rings as well for independent movement. Adjustable leg loops and waist belt have SPEED clips, so you don't have to adjust your fit each time.

Check out the back of the harness for your gear loops, tool holder slots, first-aid pouch attachment spot, and central attachment point for saw strap.

New Tribe Twist Harness

Twist Harness by New Tribe

Standard Size

Updated version of New Tribe's Basic rec climbing Harness with adjustability.

Viking Arborist Harness by Buckingham


The Buckingham Viking tree climber's harness is a tree saddle WesSpur worked with Buckingham to develop. The Viking is an affordable and dependable rope-bridge harness from the people you trust the most to build rock-solid tree gear. The Viking has a simple, uncluttered design with good geometry that transfer weight to the legs instead of the hips and lower back, and excellent padding on the leg loops. Well-padded with Drilex lining to dry faster wick moisture away, this saddle packs a lot of comfort and features at an excellent value. The saddle has snaps in all the right places for your saws, gear, and a carabiner loop on either side for a large carabiner to hold your saw.

We recommend the Viking to those who want a full-featured, reliable work saddle at a great price. This is an excellent saddle for Tree Care Company employees, who are at their most efficient and safest when working comfortably so that their full attention is on the job.
