## Customer Reviews

### ⭐⭐⭐⭐⭐ Spacious sturdy bag - Nice!
        
*by L***A on 19 November 2018*

Bag arrived today. Looks good and seems sturdy. It is a big bag. Inside (and outside) there is a small pocket which should be handy for keys etc as the bag itself is quite deep. Glad I chose grey as it looks nice. The roll top makes the bag flexible in volume. I got a discount voucher and can’t be happier with this price.
  

### ⭐⭐⭐⭐⭐ Perfect for cycling
        
*by A***R on 31 March 2019*

Was concerned about purchasing this as I couldn’t find anything online about Sinotop or the seller so it seemed a bit dodgy however the bag is really good. I’m sure they could sell more if it seemed more legit
