Personally, Kriega. One tip, if the rucksack has two zip pulls never do them up together at the top, always to one side. On a sportsbike in your lean forward crouch, air gets in between the zips and inflates the rucksack. Hey presto after a few minutes, the zips are fully undone and your contents all over the road. I followed a rider recently in the car and I kept stopping to pick up his bits. Finally caught up with him when he stopped at Boxhill for a coffee. The look on his face went from mad to happy in an instant.
You lot have got me sold on these Kreiga's now. I commute daily on my Multi & have gone through 2 cheap(ish) backpacks in as many years. Time to buy into a bit more quality. Kreiga R25 now ordered. It's deffo not cheap, but judging you all your responses, you have got what you paid for. Anxiously awaiting the postman's arrival in the next day or so.
I have Kriega stuff, and although it's very good, it does have some annoyances. I have a R30 rucksack, and US-10 and US-5 dry packs, a tank pad thingy for using the dry packs as tank bags, and a harness pocket. The first annoying thing is that the harness pocket is intended to be velcroed around a rucksack strap for easy access to phone, wallet etc - except the way the R30 straps are shaped that doesn't actually fit in the way it's intended. It can be made to work, but is less secure, and more awkwardly positioned. I believe it works as advertised on the other rucksacks, but it's frustrating that they didn't account for this on the R30 as well. Similarly, yhe dry packs are advertised as being stackable and very versatile in how they are arranged. I wanted to attached the US-5 to the back of my R30, and have the US-10 on my tank (I put some Dr Martin boots in there for walking around at my destination). However, because of the arrangement of the attaching straps and loops, the US-5 won't actually attach to the R30, so I end up having to carry the heavier US-10 on my back (on an already full and heavy R30), and the US-5 on the tank - not ideal. For kit that's advertised to be super versatile, these are frustrating limitations that you'd think could have been avoided at the design stage. Still good kit though - just check the the arrangement you intend to use actually works!
Seriously, Alpkit drybags. You will not regret them. All of the Alpkit stuff is mega. I'm a complete shill for them, and have used them for years. Love 'em.
So it looks like I might not get a rucksack now!! I might, but maybe a smaller one. I fitted Kriega straps to the grab handles on my Multistrada, so now my US-30 fits perfectly. It's secure, and easy to clip on and off, and I can fit loads in it. I'm actually tempted to get another one now to stack on top of it - would be handy for longer trips. But I may also look at something like an R15 so I've got a smaller rucksack for stuff I don't want to leave on the bike.
That is basically my setup. R15 for small rucksack duties and an US-20 for the rear, with an US-5 strapped to it for passports and papers etc.
So, I've got my R25 & tried it out yesterday. Gotta say, It's the best rucksack I've ever had. its very comfortable even with a laptop in it. Built like a battleship too
Kriega R25 which my us10 clips too plus I’ve got us20 and another us10 which all clips together, works for me but just need a dry bag for the r25 Rich
It makes me feel more extreme. I pull the mattress off the bed and shove it in the tent, and then order room service and pretend I'm on the Serengeti by streaming animal noises. Every now and then I'll go and put the shower on to make it sound like it's monsoon season. Proper hardcore.
Rookie... Just use the hotel amenities and make a mattress and sofa cushion Fort and don't tell girls the password
