Our ratings (out of 10)

1 to 10, compared with the whole market. Each says what it's based on. How we score

Weight

From maker's figures 10/10

How much it adds to your pack. 10: The best you can buy for this.

Terra Nova's key details give 210 g for the whole bivi, well under the 400 g line (its own description says 236 g and one shop says 214 g without the sack: all under 400 g).

Rain protection

From maker's figures 7/10

How well the fabric keeps out heavy, long rain. 7: Better than most.

Terra Nova gives 10,000 mm hydrostatic head for both the 15D nylon upper and the floor, in the 10,000–14,999 mm band; the floor is over the 2,000 mm line.

Packed size

From maker's figures 10/10

How much room it takes in your rucksack. 10: The best you can buy for this.

Terra Nova gives 20 x 9 cm: 3.1416 x 4.5 x 4.5 x 20 = 1,272 cm³, about 1.3 L, under the 2.5 L line (one shop lists 21 x 6 cm).

In short

Good for

  • Ultralight fastpacking, tarp set-ups and dry summer nights
  • A backup or emergency sleeping bag cover on longer trips
  • Anyone counting every gram who already carries a tarp

Strengths

  • Very light at 210 g and packs to about 1.3 L, which Outdoors Magic called the lightest on test
  • 10,000 mm hydrostatic head on the upper and the floor, with taped seams
  • Zipped mesh screen at the head end for midges
  • Drawcord hood and a half-moon foot box that tapers to save material
  • Made by a UK tent maker with in-house repairs

Weaknesses

  • Snug inside: little room for a pack or boots, and a wide mat or bulky bag will feel tight, especially at the foot
  • No hoop or roof over the head and no way to fully close the head end, so Outdoors Magic does not recommend it in very bad weather
  • The mesh screen has no support and flops onto your face
  • Few independent reviews of the current model, so condensation, comfort and durability are estimates, not reviewed scores
