For children, the Challenger K1 is an extremely fun option with its worst-case scenario of tipping over extremely unlikely due to its stability.

A bag or backpack and shoes can be stowed underneath it without taking up additional space in the boat or getting in the way.It was very easy to inflate, took roughly 7 minutes, once assembled it was very sturdy and comfortable, there was ample room for myself (in the back) and my wife, I'm nearly 6ft and had plenty of room. The quality of the material looks and feels very strong and durable, especially when it comes to kids being rough with it.

The Intex Challenger K2 is also suitable for a leisurely river or lake tour lasting a few hours, as long as you avoid ground contact and don’t have too high expectations. They were super fun to paddle, can totally be used to play bumper boats, and were even pretty comfortable.Instead, we use the safety lines for transportation, which works well due to the low weight of the kayak, as long as the kayak is not loaded with luggage.

But the used material for the boat skin is very sensitive and the greatest weakness of this inflatable boat. The whole kayak easily fits back into its oversized stuff sack as well, including all its components, like the paddles and pump.Be also careful outside the water with the kayak that there are no sharp stones or branches on the ground. Overall we found the Intex Challenger K1 one of the most comfortable kayaks we have tested with its adjustable, inflatable seat giving all-day support and comfort.
