Hilleberg specialises in making supremely functional tents that're built to endure some serious weather - and the Akto is no different. 20 years of research and tweaking has gone into perfecting the Akto for 4-season use. The Akto's single-pole tunnel design has been tested in a huge range of weather, from polar expeditions to warm weather bike-packing, and is proven to withstand extreme conditions. It's not the lightest single-person tent around but you'll thank the grams in critical conditions when help might be very far away. If you're after a solo-sized fortress for any weather, this tunnel style single-pole shelter is a sturdy choice - designed for functionality that'll last for years.
