Reflective Ironwire
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.
FEATURES
650 lbs from Dyneema® parallel strand core and partial Dyneema® sheath.
Partial Dyneema® sheath increases abrasion resistance over traditional guylines.
10x reduction in stretch helps your shelter stand sturdier in high winds.
3M Scotchlite Reflective Tracer provides nighttime visibility.

Customer Reviews
Sharing my first impressions on Durston gears I had ordered and used in Australian Alpines. Stormy conditions for three days. First off, Kakwa 55 , X-Dome 1+ weight nothing or super light. The simple and practical design of Kakwa eases loading and unloading gears with carefully thought-out spacious exterior pockets and tie-down. The X-Dome 1 plus was simple and quick to set up. I had made four critical guy lines ready and attached them considering the storm conditions. It did quite really hold up well upto 65Km/hrs wind gusts at alpine snow for about 11 hours. While I feel the intense pressures at times, utilising both trekking poles stabilises the integrity and it stood firm against strong winds.
Overall, I am quite impressed with how these gears have performed. I can confidently hike and camp knowing my gear will function as intended.
Will be using them in the next few adventures, trip and weather conditions.
Lastly, I would like to share the exceptional support they extended when I had some hiccups with shipping. Dan and the team stepped in to make sure the package arrived on time and even absorbed some of the additional charges. I highly appreciated this kind gesture of customer support.
Thanks for the kind words and using our gear.

I like this guidewire a lot. I've the guidewire, x-dome 2, footprint for the x-dome, kakwa 55 in ultra 200x, and iceline poles. Im absolutely thrilled to have chosen equipment thats pratical and works right out of the box “sometimes package.” Thank you so much for the time involved in research, engineering, and distribution.
Just what I needed. strong line that dont swell form water retention and is very durable.
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.
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.
