Tailored to fit your Helinox Chair One (sold separately), and designed for maximum airflow, the Summer Kit is a replacement seat that keeps you cool and dry on hot summer days. It’s easy to use – the tailored design simply attaches where the chair’s original seat goes – and is made from a nylon monofilament mesh that’s light, supportive, comfortable, strong, and resists damage from the sun’s rays. **Chair One Frame Not Included**
