I was in the market for a new (and more roomy) wash bag. After a short look on Amazon I found this one, from appearance it was just what I had in mind.The bag has just one compartment. Which personally is what I prefer, as dual compartments mean that sometimes you can open one compartment looking for the item you need, just to then find out that it's in the other compartment. With some other wash bags, its necessary to purchase travel sized (smaller sized) toiletries in order for them to fit in. This is not the case with this wash bag, as you are able to fit full sized toiletries in.The inside of the bag in lined with a waterproof material, so if you need to put any wet/damp wash items in the bag it will not soak through to the outside of the bag. This is extremely useful if you have this bag in your suitcase with the rest of your luggage. Also going off of the item description, the outer material is waterproof and dirt proof as well.On the outer there are no pockets or compartments.The construction of the bag looks excellent. Thick and excellent quality material, thick durable carrying handles and also the zip seems of a high quality too, and to top it off, the wash bag is extremely good value for money too.To sum up:Well there's not much more I can say apart from that if you want a large wash bag, cosmetics bag, or some other large zip up bag for some other use, then this bag should be at the top of your list.
