5.0 out of 5 stars Great bag for washing clothes on the go
Reviewed in the United States on December 1, 2015
Verified Purchase
I use this for washing my clothes on the go. Wasn't sure about strength, size, etc. even after googling for a while.

I took a 8L bag and it's perfect:

- I can wash about 3 tshirts 3 pairs of socks and 3 briefs with enough space for watering around (its about 60% full with these items inside)
- It's solid, even thus it's super thin - I have no worry. It wont break when I use it to wash/massage it. Feels solid.
- waterproof obviously, its not leaking so that's good ;-)

Nothing I would dislike really. Works exactly the way I wanted. Yay!

Great product but prefer to use s2s compression sacks for backpacks because they reduce the size of items to save space.

I used to use a trash compactor bag, but this is much better, and should last years. Trash compactor bags are great pack liners, but hard to find in singles.

Great light weight bag!
The transparent side is excellent to select what you want before you break the seal and open the bag.
The air trapped in the bag helps float main pack and keeps the contents dry.

5.0 out of 5 stars Super comoda e resistente
Reviewed in Italy on April 12, 2018

Comodissima sacca stagna, comprata a colpo sicuro in quanto ne possedevo altre della stessa ditta di dimensioni più piccole! La utilizzo caricando in maniera abbastanza stressante, con le mute da sub bagnate per il trasporto verso casa! Resiste perfettamente, non fa uscire un goccio di acqua, e poi basta un risciacquo ed è subito pronta per essere asciugata e riutilizzata!
