portable sauna tent offers weather protection for year-round outdoor use

Jordan Boon and Harry Beardsley unveil portable sauna tent

Jordan Boon and Harry Beardsley of Southsea, UK, reimagine portable saunas with the PortaSauna HEX, designed specifically for the challenging weather of Northern Europe. The robust, semi-permanent sauna tent is intended for long-term use in outdoor settings, withstanding harsh elements without compromising portability. Its stitching pattern creates larger insulation pockets, allowing for improved heat retention, and enabling faster drying after exposure to rain. The thicker TPU (thermoplastic polyurethane) windows help maintain internal temperatures by reducing heat loss, making the sauna effective even in colder climates. With its semi-permanent capabilities and high-quality materials, it provides a year-round outdoor experience while traveling or as a garden retreat.

PortaSauna HEX features a compact wood-burning stove

Built in 2024, the PortaSauna HEX is crafted from upgraded materials, including a 600D outer fabric (up from 300D in previous models) for the roof and corners and 420D (previously 300D) for the walls, protecting against rain, snow, and wind. Its enhanced insulation, with cotton wadding, increased from 90 gsm to 170 gsm, improves thermal retention, while a 420D fire-retardant inner liner ensures safety during use. The hexagonal stitching pattern further boosts the sauna’s heat retention and drying capacity, making it a durable and efficient choice for outdoor use.

At the heart of the experience is the PortaStove, a compact wood-burning stove that quickly heats the sauna to optimal temperatures. The stove reaches 78°C (172.4 F) in 15 minutes and can achieve a maximum temperature of 100°C (212 F) in just 45 minutes. This efficiency, combined with the upgraded insulation, allows users to enjoy a hotter, more efficient experience using less wood.
