## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent item, strong and tiny
*by M***S on 10 July 2025*

Great item, super light and small but really strong

### ⭐⭐⭐⭐⭐ EXCELENTE PRODUCTO
*by A***R on 30 September 2021*

Muy práctico pero muy caro para lo que es.

### ⭐⭐⭐⭐⭐ Strong and light - good for carry on baggage for under 7kg limits
*by P***A on 10 May 2023*

Fabric is strong for the weight, and the bag packs down into a tiny ball when not in use. I use this for regular trips interstate and the airline carry-on baggage limit is 7kg. Weighs nothing and fits three days worth of clothes in it (for summer and autumn climate in Sydney, NSW, Australia). The straps are not padded at all, so it is a basic design, but very useful in saving weight. Highly recommend for light travel.
