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
Leakproof*
Reviewers' average 7/10How reliably it stays sealed in a packed rucksack.
4 reviews on leakproof, e.g. "the leaks have come on slowly, so it’s easy to notice when the seams are close to splitting.".
Reviewers disagree on this.
Durability*
Reviewers' average 7/10How well it survives knocks, drops and daily use.
5 reviews on durability, e.g. "Bomber Durable – my last Platy Water Bottle lasted for 8 years of near constant use".
Reviewers disagree on this.
In short
Good for
- Extra water capacity for dry stretches or camp, at 36 g for 2 L
- A dirty-water bottle for a squeeze filter (Section Hiker uses it with a Sawyer and plumber's tape)
- Hikers who will treat a soft bottle as a cheap part to replace
Strengths
- 36 g for 2 L (18 g per litre), well under the 100 g/L line for the top weight score
- Stands up on its own when full (CleverHiker)
- Taste-free out of the box and stayed neutral (CleverHiker, Hiking Insights)
- Dishwasher safe when fully expanded (Platypus), though 2 L and larger bottles may not fit
Weaknesses
- Seams are the weak point: CleverHiker says every Platy it owned eventually split there, and one tore in a drop test
- Cap is not tethered, so it is easy to lose (Section Hiker, Hiking Insights)
- Two hands to drink from when full, and slow to fill from shallow water (CleverHiker, Hiking Insights)
- Platypus gives no rolled-up size, so we cannot score packed size
- Trekitt lists 40 g against Platypus' 36 g
