My trip to Fiji was for seven days so I needed a minimal amount of clothes and extras. I was staying at The Novotel so knew there would be towels, some toiletries and so on. This meant I could reduce what I took by around 20% on other trips and therefore, decided to travel with my One Planet Traverse daypack as carry-on luggage.
I use this One Planet daypack a lot for those smaller trips. It’s volume is 38 litres which is a generous size for a short trip. I like the simplicity of this pack. Only one pocket on the top and minimal straps that annoy me because they get snagged and caught on things.
