Hilleberg Saivo 3

The Hilleberg Saivo 3 is a self-supporting dome tent built for situations where the tent has to survive unattended for days or weeks at a stretch — high-mountain base camps and polar expeditions rather than fast hiking trips. At 5300 g packaged weight for 3 people (roughly 1.8 kg per person), it carries real fabric and pole mass that Hilleberg puts into its extended 3+ season rating, meaning it's built to shrug off wind and snow loading beyond what a standard 3-season tent handles, though it isn't a full winter/expedition (4-season) design. Being self-supporting is the practical payoff of the dome shape: the tent holds its form without guylines, so it can be lifted and shaken free of snow or repositioned on hardpack and rock where stakes won't bite — a genuine advantage at an unattended base camp when nobody is there to dig it out after a storm. At over 5 kg, this is not a pack for someone counting grams on a multi-day trek with daily camp moves; for that, Hilleberg's own Allak 3 is the lighter option. The Saivo 3 suits expedition leaders and mountaineers who pitch once and leave the tent standing for an extended period in exposed terrain.
