World's Highest Performance Guyline

Overkill perhaps, but for the gear geeks who want the best, our Reflective Ironwire uses Dyneema® fibers in both the core and sheath to become the toughest and lowest stretch guyline available. Like our tents, it maximizes function and durability for the weight.

CONSTRUCTION

Reflective Ironwire has a pure Dyneema® core which gives a breaking strength of 650 lbs – remarkable for a 2.0 mm line. A few strands could lift your car.

While other Dyneema® core lines exist, ours goes a step further and also weaves Dyneema® fibers into the sheath for unparalleled abrasion resistance. A pure Dyneema® sheath would be too slick to hold knots well and wouldn’t melt nicely to finish the ends, so our sheath uses a crafted blend of Dyneema® and polyester for the ideal balance between durability and feel.

Reflective Ironwire line is craft made in the USA by Lawson Equipment. It is equivalent to their regular Ironwire cord, except we have added dual 3M Scotchlite Reflective reflective tracers for excellent night time visibility – key for a tent application.

PERFORMANCE

The Dyneema® fibers combined with a tight weave make this line ultra low stretch, which let's your shelter stand sturdier in the face of windy conditions.

Regular guyline typically stretch about 10% under a load which allows your tent to deflect under high winds and snow loads. This line reduces that 10x to about 1% stretch, which largely eliminates stretch for a more resolute shelter in harsh weather. While often overkill, we recommend this line as an upgrade when camping where high winds or snow loads are a factor.

Both the Dyneema® and polyester fibers also shun water, which reduces water weight gain and speeds up drying.

Quality Line

I took my new X-Dome 2 into the Holy Cross Wilderness in Colorado in June 2025 and set it up in a sheltered spot overlooking a lake. Despite the location, a strong wind gust hit for about two minutes and pushed the tent inward. That’s when I realized I needed guy lines at the tent’s attachment points. This product worked great and felt solid—I made six guyout lines with it.

Super Strong

I have some Lawson equipment reflective iron wire that says it has 650 pounds breaking strength and I can cut it with a pair of regular kitchen scissors. With the Durston iron wire, I tried to cut it with the same scissors and they won’t cut it at all. I tried two pairs of heavy duty scissors, including a pair of very sharp heavy duty shears that would cut your finger clean off and they won’t cut this all the way through, they only fray it because it’s so strong. This stuff is amazing. I’m using it for guy lines on my tent, and I would bet even if it was a bit frayed it wouldn’t break in heavy winds. Highly recommend.

Gen3 X-Mid problem resolved

I bought the Gen3 X-Mid 1. I initially loved the tent but this quickly soured when all of the corner tie out points slipped through the buckle when under pressure.
I emailed Durston Customer Service asking for advice and promptly received a personal email back (not generic) going over the problem and how they thought they'd fixed it on the Gen3.
I was given some temporary fix advice and also sent some Ironwire for free to replace the corner tieouts. This completely fixed the problem. I also replaced the 2 guy out points as these also slipped under pressure.
I know love my tent again and have total trust in the product, and also Durston as a company. This is quite literally the best customer service I have ever received.
