Review: Great little backpack - Very comfortable over my shoulder, lightweight and easy to access the pockets. Will be taking it on holiday. Can get all the bits I need, sunglasses, passport, tissues, lipsalve and phone. Great quality too. Love their products.
Review: Good day bag but minor flaws - A decent bag for the price, the "lock" on the zips (effectively a mini carabiner) is a really handy feature and made me feel more secure keeping the bag on my back. It's a decent capacity for everyday items but don't expect to be able to fit any large devices or a water bottle. Being able to switch which side the strap goes is also great. The strap is unpadded but relatively comfortable. The main issue is the front pocket closes via a button that does not stay closed even with nothing or minimal items inside it, making it feel incredibly unsafe to leave anything in there (I have had items fly out).

## Features

**Q: Is this available in a medium size?**
A: It depends what you mean by medium size. This is a small bag meant for small items like phones and keys etc. As an indication, my iPad Air fits in but the bag will not close. It’s a good bag for what I use it for.

**Q: Could a 500ml water bottle fit in the bag?**
A: Yes it will.

**Q: Could you fit a lightweight jumper in here? i would like it for the Disney Parks but the aircon is freezing!**
A: I don't think so I usually carry my phone and my camera and my spectacles and my wallet etc. no items of clothing I'm afraid just my valuables like it says it is antitheft so keep everything secure. it's not a huge bag but worth it's weight in gold especially when travelling abroad to places that have a lot of pickpockets I know my valuables are safe always.

After ordering one for a present I ordered one for myself, as described in the title it’s small but exactly what I was looking for. It will be ideal for when I go walking and to take in holiday, big enough to carry phone, money etc. lots of colours to choose from and looks well made.
