Both zips on my old Camelbak Lobo bag failed on the same ride so I decided to buy a new backpack. The Lobo was always a bit uncomfortable and I used to overload it on long rides (probably why the zips failed!) so a slightly larger, more comfortable bag was what I was looking for. Lidl currently have some quite nice looking backpacks
for £16.99 but at 25L capacity, they are way bigger than the Lobo's 10L. I found a suitable
15L bag on Amazon (which looks like it was made by the same company) so I bought one of those instead. I used it on a quick ride today. It feels more comfortable than the old bag (wider straps and a mesh panel to hold it slightly away from my back) and the extra capacity will come in handy on long rides in variable weather conditions when I may want to add or remove clothing, and/or carry food & drink, and/or spares.
I needed to get the order over £20 to qualify for free delivery so I also bought a second
bottle cage for my singlespeed bike. I hadn't expected to need 2 cages on that bike because it was supposedly just for short local rides but in reality I have used it for several metric and imperial century rides, plus a couple of 200 km rides. Blimey - it was £3.00 a couple of days ago but it has now gone up to £5.99!
Best thing of all - I used the cashback from a recent holiday to pay for the order!
