## Description

ROCKBROS 20-35L Motorbike Saddle Bag Hard Shell Waterproof Motorcycle Tail Bag with Rain Cover for Storage, Travel, Cycling : desertcart.co.uk: Automotive

Review: Good bit of kit - I bought this for my husband after weighing up between material/leather or hard shell type. He said he ‘needed’ something sturdier for his locks and chains. He loves it. Adores it. Thinks it’s a great invention. You get the jist. It’s very easy to attach to his motorbike and once in position, it holds sturdy. There are two extra zips which provide extra space up over if needed. He carries everything he needs for work in it lunch, shoes etc as well as the chains and locks. He hasn’t tested it in the rain so I can’t comment about how water proof it is, although it does come with what he thinks is a ‘dry bag’ and I’m pretty sure once you arrive at your destination it can be removed and used as a backpack of sorts. All in all, a good piece of motorbiking kit and extremely good value for the price. Oh and a happy husband!
Review: Excellent in all respects - Looks beautiful on my BMW (on the Isle Of Man TT course), I took this photo by slipping my phone tablet out of the bag and in no time was on my way. All important stuff I put in this in this; its been completely secure going for 100s of miles. I just detach in seconds and take everywhere with me as a shoulder bag. The ability for it to expand is brilliant, I havent even used the 2nd expansion as not been necessary yet but great to have in reserve. Really well made, top of box is hard and design is great. Comes with a rain cover. Installation of straps really easy and well explained. I use it as my carry round bag without motorbike, so when it comes to using it on the mbike Its second nature to click it on and go...well done Rock Bros 5*****

### ⭐⭐⭐⭐⭐ Good bit of kit

### ⭐⭐⭐⭐ Really handy tail bag
*by O***R on 8 July 2025*

It's a really nice looking bag or soft top box. It seems rather sturdy and can contain your tools or lunch pack etc The only issue I noticed rather quickly is the central strap leaving marks on the seat. I've got a feeling that the seat might get damaged in the long term. Either place a cloth between the strap and the seat or use a spare pillion seat exclusively for the tail bag I had a spare but slightly damaged seat (with a ripped cover) and I attached the bag onto it and will just alternate pillion seats according to my needs which seems the easiest option for me.
