Backpacking Light Aircore Pro "UrsaLite" Dyneema Bear Bag Hanging Cord (50 feet)

Ultralight bear bag hanging cord. Urethane-coated Dyneema for light duty bear bag hanging.


AirCore Pro "UrsaLite" Bear Bag Hanging Cord is a 2.2 mm diameter braided cord suitable for light duty load hauling applications. With a breaking strength in excess of 650 pounds, this rope is the ultralight choice for bear bagging by ultralight hiking and lightweight backpacking enthusiasts, and is the same cord used in the UrsaLite Bear Bag Hanging System. As a bear bagging rope, AirCore Pro UrsaLite offers unmatched handling and abrasion resistance, with its proprietary polyurethane coating.

For an even lighter, and thinner version of this cord, that is more suitable for tent and tarp guylines, please see the AirCore Pro Guyline and Tensioner Kit.

AirCore Pro "UrsaLite" Bear Bag Hanging Cord is a braided cord of 100% pure Dyneema (Spectra) fiber construction, which offers a higher strength-to-weight ratio than any other fiber.

Because AirCore Pro "UrsaLite" is a non-rotational rope with no stretch, it is ideally suited for bear bag hanging for loads of up to 600 lbs.

AirCore Pro "UrsaLite" is flexible, spliceable, and highly resistant to fatigue failure, which is common among other spectra ropes. AirCore Pro "UrsaLite" is coated with a polyurethane finish that dramatically increases handling ease, minimizes tangling, and offers outstanding abrasion resistance.


As with all Spectra / Dyneema ropes, choice of knots is critical, and it is recommended that inline bight knots such as the bowline, double figure eight, or double overhand, used for terminating ends with loops, rather than slipknots such as tautline or half hitches. For hanging things in trees, and then tying off the rope, use a Timber Hitch or double half hitch.

Spectra / Dyneema rope does not "burn pretty" at the ends, but with the urethane coating present in this rope, it burns far better, and resists fraying better, than uncoated Spectra / Dyneema cord and rope. Some people liked the polish look of wrapping one or two turns of electrical tape around the end of the rope to prevent fraying, or using heat shrink tubing. Either way, be sure to place a light coat of 5-minute epoxy on the rope under the tape or tubing, so it resists sliding off the end of the rope while in the backcountry.


The coating effectively eliminates the need to coil the rope. Just stuff it loosely in your bag, and it will remain untangled. Really - you have to try pretty hard to get this rope tangled up. It's quite stiff! If you do coil, be sure to do so without any kinks or twists in the rope, which hinder throwing and cause unncessary friction when sliding over tree limbs.

Appropriateness for Bear Bagging

This cord is not appropriate for stringing loads greater than 30 pounds in softwood trees, such as pine, in wet conditions (spring). You risk cutting into the soft bark and getting the cord stuck. Cutting into the bark is a problem mostly with heavy loads, while getting the cord stuck in an existing bark groove is mostly a problem with light loads. So, the usual context of this happening is in an area where the same limb (and bark groove being cut by the cord) is used for multiple consecutive days in a base camp situation. If you don't run into this situtation when you hike, then this cord may be OK for you.

For light duty bear bag and pack hanging this cord is suitable for virtually any tree type and climate.

For heavy duty hauling, especially in soft wood trees in the spring, we recommend that you use AirCore Pro "Ursa" Bear Bag Hanging Rope. It's only a little heavier and easier on your hands for heavy loads.


  • Highly abrasion-resistant, low stretch, tangle free rope that slides easily over even wet bark.
  • Does not absorb water into rope core, unlike uncoated braided spectra cord, poly cord/rope, or manila ropes. Water absorption reduces strength and adds weight to all ropes, and provides serious handling limitations below freezing temperatures.
