Our ratings (out of 10)
1 to 10, compared with the whole market. Each says what it's based on. How we score
Waterproof build
From maker's figures 6/10How well its build keeps water out, from the published seams, closure and submersion claim. 6: A bit better than average.
Fully taped seams and a roll-top closure with a lightweight buckle. There is no submersion claim: the 10,000 mm hydrostatic head (in the feature list and FAQ on Lifeventure's product page) is a fact, not a score. The 3 band.
Weight for its size
From maker's figures 4/10How much it adds to your pack for the space it protects. 4: A bit below average.
48 g for 5 L is 9.6 g/L, in the 8.5–11.9 g/L band (Lifeventure's figure for the 5 L).
In short
Good for
- Keeping a spare layer, electronics or a first aid kit dry inside a rucksack
- Use inside a pack, not for being under water
Strengths
- Fully taped seams and a roll-top closure
- 70D siliconised ripstop with a polyurethane coating
- 10,000 mm hydrostatic head (Lifeventure's figure)
Weaknesses
- 48 g for 5 L (9.6 g/L) is heavy for its size, about twice the weight per litre of a 30D ultralight bag
- No submersion claim from Lifeventure
- No independent reviews found, so durability and ease scores are missing
