Our ratings (out of 10)

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

Weight for its size

From maker's figures 2/10

How much it adds to your pack for the water it holds. 2: A weak point.

Alpkit lists 507 g for 1.0 L: 507 g per litre, just over the 500 g/L line.

Packed size (empty)

From maker's figures 3/10

How much room it takes up when it is empty, for the water it holds. 3: Below average. Fine for some trips, not others.

A rigid bottle does not shrink, so we draw it as a cylinder from its height and width. Alpkit gives 300 mm tall and 84 mm across: 3.1416 x 4.2 x 4.2 x 30.0 = 1,663 cm³, so 1.66 L empty for 1.0 L held (1.66 per litre), in the 1.3–1.79 band.

In short

Good for

  • Camp and group days that need one big hot-drink flask: 1 L is two to three mugs
  • A budget insulated flask for car camping and day trips
  • Sharing a brew: the cap doubles as a 100 ml cup (Alpkit)

Strengths

  • Leakproof lid and a cap that works as a small cup (Alpkit)
  • Made from recycled stainless steel (Alpkit)
  • 3-year Alpine Bond: Alpkit repairs, replaces or refunds a faulty product

Weaknesses

  • 507 g for 1.0 L: just in the heaviest weight band, and 1.66 L of pack room for 1.0 L of drink
  • Alpkit gives no hours of heat or cold, so we show none
  • The cup is small, about 100 ml (Alpkit)
  • No independent review of this size was found, so ease of use and durability are estimates, not reviewed scores
