Irukandji - Set

Regular price $11.95 $0.00

Irukandji is a very special rounded/rectangular polyester string. It is soft and provides great snap-back and feel. It enhances spin potential due to its added elasticity. It was engineered to function as the ideal Cross string.

Its smooth surface allows the mains and crosses to slide on each other, minimizing notching and maximizing snap-back, which increases spin potential. With remarkable feel and comfort, it bridges the gap between co-poly and multi filament strings.

Performs well in full bed, but is highly recommended as a Cross-string with Multi or Natural Gut in the Mains.

Available in White, Blue and Grey colors.


Diameter: 0.90 x 1.45 mm

Recommended tension:

- Normal poly stringing tension when used as full bed or as a Cross in a hybrid.


Note: Given Irukandji's unique shape, it is officially rated at 0.90 x 1.45 mm in diameter, which is comparable to a 17g round string.


Individual 12m Set

 Approximate string weight with zip ties and no packaging: 19 grams.

Stringing Tips:

- Irukandji will tend to lay against the gut or multi main on its larger surface area, flat side. Don't worry if this does not happen every time, and you see a turn or two throughout stringing. It will not be a problem.

Awesome cross string!

The string is slick and allows the mains to move freely. The snapback is excellent. I strung this with Alpha in the mains and Iru in the crosses. This made my Speed Pro's stringbed more lively and added needed power!

Excellent, Bradley! Even though Irukandji was engineered to work best with gut or multi in the mains, it is still an amazing cross in a dual poly hybrid setup. Happy you like it.

Great cross string with NG

I have about 6 hours of hitting with a Blade 16m, NG @56 lbs mains, Irukandji @ 54 lbs crosses. It has a great feel, control and comfort while offering more spin than any gut/poly hybrid I’ve tried in the Blade 16m thus far. Very impressed! The only downside, which Grapplesnake has made clear, is the extra attention to detail while stringing. I am not a stringer but talking to the person who strung it and has no experience with this string previously, they said it was quite difficult. I’ve found a few places where the string is twisted and the wider side isn’t sitting flat on the NG but so far hasn’t cut into the NG.

Thank you, Kevin! Enjoy Irukandji!

Best Cross

Best cross I have used with a multi/gut. Seems to greatly increase durability and snapback of the mains.
much better than any other poly as a cross including ALU.

Very useful string

Irukandji is a problem solver when used as cross strings. 1) If your current polyester strings feel a bit brittle or brassy, putting these in the crosses will soften up the string bed pretty nicely. 2) If you're a topspin hitter looking for a little more springback from the mains, these will help. They are more slippery than average. And 3) if you're getting a lot of notching or early breakage in your main strings, the larger surface area and low friction will help your mains last a bit longer.

I'm coming to these from a hybrid setup consisting of Yonex PolyTour Spin 16L in the mains and Solinco Tour Bite 20 in the crosses, both at 50 lbs. For me, this string does add a bit more power.

Great string!!

I normally use a gut/co-poly hybrid string in my racquets. I was anxious too use the Irukandji as a cross.
I was surprised how much spin and control I was getting off this combination. Nice feel at the net as well. No harsh vibration from hard hot balls coming back from the other side when at the net. Most other co-poly crosses I had been using are lacking that feel and softness at the net. I did not feel that with the Irukandji strings in my racquet.
The Irukandji strings last longer than my previous setup with some other hybrid crosses. That, for me, is a big plus. I do not waste a lot fo time restringing my racquets and spend that time on the court.
I am happy with the Irukandji strings and will use them in as my regular "go-to" set up.
I will however try more of the great Grapplesnake strings in some of my other racquets as well. I have told my other tennis friends about these great strings.
Try the Irukandji out as a cross. I do not think you will be disappointed.
Great strings- Great value!!!
