Etan Trampoline safety net 12ft / 366 cm grey. If you see children jumping on a trampoline, you understand why a safety net is required. It’s a lot nicer for both the ones on the trampoline and the ones next to the trampoline if you know you can’t land next to the trampoline. This net is made of anthracite grey and is especially suitable for an upright Etan Premium trampoline of 366 cm. Made of the best materials, this stable safety net ensures that no accidents happen, without you losing it completely in your garden. The net is made of such a finely meshed material that you can easily see through it.
