Well most people would want to compromise on biking gear. But if like me, you spend every minute of your free time on your bike, then it pays to have the best kit available.
I’ve been a fan of Kriega stuff when I went and got myself a US20 tailpack for that odd weekend away. Impressed with how waterproof it was and its ease of use, I went and got myself a US10 to turn it into a US30 tail pack.
I then realised I needed a suitable bag for commuting because my Boblbee megalopolis was becoming that bit uncomfortable on the lower back. It does look awesome and tecchy but it’s cumbersome when you’re in a crowded room and the shape of the moulding doesn’t make efficient use of the available volume. So I ended up getting Kriega R20. Because I loved the R20 so much, and since I already have a US30, I went and got myself an R30! 
Here are my video reviews for them - but look down for the summary

Kriega R30
Pros
- Can fit a 14" laptop

- Increased carrying capacity. Pretty much like having a US30 on your back! But very comfortable
- Weight carried on your chest.
- Fully waterproof
- Can fit US10

Cons
- Even more £££££ But should be the ONLY backpack you will EVER need to buy
