So, had a few rides with this now, and I really like it.
The fit is good and whilst it seems quite long when you hold it, it doesn’t seem to interfere either at the waist or the neck whilst riding.
It seems to sit differently on the back compared to ‘normal’ shoulder strapped bags – this may be something in common with all harness-style packs?The weight seems to be distributed more on the lower back and your sternum, rather than on the tops of your shoulder.
This is a bit weird at first, and when climbing the unweighted feeling on your shoulders is odd, but quite nice! However, as soon as you start going down the weight distribution is spot on and I’m feeling no movement or swinging at all.
The build certainly seems sturdy, and it didn’t let any water in the one wet ride I had with it, even without using the waterproof cover.
Amount of storage is good. The large compartment next to the bladder easily fitted a softshell jacket. Spare tube and some fruit. The smaller front compartment has lots of mesh pockets and a zipped compartment. Plenty of room for phone, pump, multitool, etc. I haven’t used the helmet carrier, but size seems good. And the 2 waist pockets are spot on for keys, etc.
The back panel felt a little rigid on the first ride – probably due to the rubber/plastic back protector insert. But it seems to have moulded to my body shape a bit after a few rides. The padding on the back is good, not too soft, but comfortable. Air flow is ok, but it might be a bit hot in really warm conditions.
The included bladder is very good – I’ve not had one with a sliding top before, and it makes refilling very easy. Hose is just the right length, but the water flow is a little slow. Just need to suck a bit harder!
Overall, £40 well spent 😀
