SW-MOTECH Legend Gear LH2 Side Bag To Fit SLH Side Carriers for Harley-Davidson Softail Models | Left

The bag is solidly constructed however not overly beefy. It does not sag thanks a cleverly positioned spacer by the belt guard that you will need to install that comes with the bracket (bracket kit sold separately). The quick de attach system, while a little hard to understand at the beginning, is a breeze to use once you get used to it, no tools required, no rattling while riding either.
The flat of the bag is also not flimsy and with the lock, it stays put.

The saddle bag is NOT waterproof, in a heavy downpour water can get inside and at the bottom it has a tiny drain hole so it does not accumulate.
Because of that, you do get a removable fully waterproof dry bag to put your essentials in it, which fits perfectly inside the bag, mine came with 2 of those so I also got a spare one.
This means that on trips, you can easily just carry your stuff in and out of the bags to your hotel or camp site inside the dry bags.

The only complain that I have is that the lock (also sold separately but it is only $10), is a little cheap and not so easy to install since the nut can strip easily, I wish those came installed.

The best thing about this bag and the mount kit is that it needs absolutely zero modifications and you don’t have to worry about doing any turn stock signal relocations. When removed the brakes and the spacer are all black and blend well with the strut line and frame.

I have to say I am really happy with this bag, even at this price point, it is a worthy investment for anyone looking to carry some essentials or planning to go on trips.

To Twisted Throttle, I would say that it would be more helpful if you guys can sell everything, both bags, bracket and locks as a complete set. It is a little confusing to be purchasing everything separately, since you can buy specific sides as well. Also, because of the popularity of the bike, I can also assure you that this fits on a Softail Low Rider S.
