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 8/10How well its build keeps water out, from the published seams, closure and submersion claim. 8: Clearly better than most.
Ortlieb says it permanently welds all seams, and the bag has a roll-top closure. It is rated IP64 (splashes from any direction), with no submersion claim: the 4 band (welded seams and a roll-top).
Weight for its size
From maker's figures 8/10How much it adds to your pack for the space it protects. 8: Clearly better than most.
108 g for 22 L is 4.9 g/L, in the 4.0–5.9 g/L band (Ortlieb's figure; Ultralight Outdoor Gear gives the same 108 g).
What reviewers say (out of 10)
Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score
Durability*
Estimate: only 2 reviews about durability (fewer than the 3 we need, so never above 8) 8/10How well the fabric and seams resist scuffs and holes.
2 reviews on durability, e.g. "in our tests the fabric held up against sticks, rocks, and asphalt, despite acquiring a few visible scrapes on its exterior.".
Ease of use*
Estimate: only 2 independent sources about ease of use, as shop reviews count as one (fewer than the 3 we need, so never above 8) 7/10How easily it closes, seals and packs.
3 reviews on ease of use, e.g. "The bag is easy to pack, and it makes a great bag-within-a-bag, too, when you’re packing for longer outings.".
In short
Good for
- Squeezing a sleeping bag or clothes down inside a rucksack: the valve lets the air out
- Rain protection inside a rucksack, with welded seams
- Not for river crossings or anything that may go under water
Strengths
- Welded seams and a roll-top closure
- Valve in the base lets the air out for compression
- 108 g for 22 L (4.9 g/L)
- Tougher, tear-resistant base with a loop for pulling it out of the pack
- 5-year warranty, and Ortlieb can reweld holes
Weaknesses
- IP64 means splash proof, not submersible
- Ortlieb says the roll-top must be rolled 3 to 4 times and secured downward to reach IP64; Ultralight Outdoor Gear says at least 5 to 6
- Ortlieb says it is not suitable for storing food or drinking water, and the bag shouldn't be stored rolled up
- No independent reviews found, so durability and ease are estimates, not reviewed scores
