Representing a new generation of lightweight shelter design, with the use of trekking poles and advanced materials, delivering a refined, minimalist structure. Designed for solo backpackers who prioritise an excellent size-to-weight ratio. Compact packability and reliable protection.

The TriPlex™ flysheet is constructed from 20D Triple Ripstop, solution dyed, PFC-free recycled nylon/poly fabric with a high-performance Si/Si coating and a 3,000mm hydrostatic head, offering dependable weather protection while keeping weight to a minimum. The 20D recycled ripstop nylon groundsheet features a robust Si/Si coating and a 5,000mm hydrostatic head, providing confidence on wet ground without adding bulk. The inner tent uses 15D recycled ripstop nylon with PFC-free water-repellent treatment and solution-dyed mesh, delivering excellent ventilation and comfort for three-season use.

Pitched using trekking poles, the iO 1 is also supported by two 8mm TN Reflex alloy end poles to increase inner tent volume and flysheet stability. The half-mesh inner design strikes a balance between airflow and protection, making it well-suited to variable conditions on long-distance routes.

With a remarkably compact packed size of just 30cm x 12cm, the iO 1 disappears easily into a pack. Lightweight Terra Firma Mini pegs and Dyneema® reflective guylines complete the setup, ensuring secure pitching even in exposed camps. Designed with sustainability at its core and performance in mind, the iO 1 is ideal for those who want to move further, faster, and lighter.
