Description

A true four-season expedition shelter, purpose-built for three-person teams operating in the most severe and remote environments. Its exceptionally strong geodesic design is supported by five 9.5mm TN Reflex poles, creating a highly stable structure capable of withstanding extreme winds, heavy snow loading, and prolonged exposure in hostile conditions.

The flysheet is constructed from Watershed 70D nylon ripstop with a high-performance Si/PU coating, delivering a formidable 7,000mm hydrostatic head for outstanding waterproof protection. Underfoot, the Waterbloc 210D nylon groundsheet offers an impressive 10,000mm hydrostatic head, ensuring complete protection from saturated ground, snow melt, and prolonged storms. The durable 70D ripstop inner, treated with C0 water repellency and combined with SD mesh, balances toughness, ventilation, and comfort for extended four-season use.

Designed to comfortably accommodate three people, the Expedition Hyperspace provides generous internal volume and a practical layout suitable for long-duration expeditions and basecamp use. The robust structure maintains its shape under load, preventing inner sagging and preserving usable space even in extreme conditions. High-strength Terra Firma pegs and Dyneema® reflective guylines ensure secure anchoring and improved visibility in exposed terrain.

Guarantee

Lifetime Guarantee

Loading... is covered by a lifetime guarantee offering long‑term reassurance to the original owner for the usable life of the product. This refers to the period during which the item can reasonably deliver the performance it was designed for - something that naturally varies depending on how it is used, the conditions it is exposed to and the care it receives. A product used frequently in demanding environments will naturally have a shorter lifespan than one used occasionally and well maintained. For this reason, we assess each case individually rather than applying a fixed timeframe. While this guarantee covers all Terra Nova products, tent and bivi poles are excluded, as they are protected under our dedicated No‑Quibble Alloy Pole Guarantee

Two-Year Pole Guarantee

Every alloy pole supplied with Terra Nova and Wild Country tents or bivis is covered by our No‑Quibble Pole Guarantee. For two years from the date of purchase, we will replace any damaged pole - regardless of the cause, including unforeseen mishaps or accidental damage. This straightforward, hassle‑free policy ensures you can rely on your equipment with confidence, knowing that any tent or bivi pole issue will be resolved quickly so your adventures can continue uninterrupted.
