Naturehike Opalus Tunnel 3

The Naturehike Opalus Tunnel 3 is a non-freestanding, 4-season tunnel tent for three people, pitched inner-first, and it depends entirely on correct staking to hold its shape — without stakes it won't stand at all, worth factoring into campsite choice on rocky or frozen ground. The 19 stakes included reflect that stability here comes from anchoring, not pole geometry. Both fly and floor use 20D silicone-coated ripstop nylon rated to 4000mm on each side. Trail weight of 2600g (3100g with accessories) works out to 867g per person — a solid, if not extreme, figure for a 4-season 3-person tent. It has two doors but only one vestibule, so the second door functions more as a secondary exit than a full entry point with gear storage. A 4.56m² floor at 190cm width gives three people enough room to lie side by side across the 240cm length. It packs to 60×18.5cm. The Opalus Tunnel 3 suits group expeditions into harsher mountain weather, where space for three matters more than shaving the last grams.
