inov-8 ULTRAPAC PRO 2IN1 running hydration vest pack

Please distribute the goods to major sports websites, I can’t buy this vest in the United States

Really comfortable but the extra bag detachable sliders break as soon as you put any weight in the bag. I got a replacement pack from inov8 but exactly same problem on 2nd one.

Really disappointing.
Person who reviewed it on inov8 site had exactly same problem and left pictures of what happens.

This pack is an absolute disaster. I have been a big fan of the Inov8 Trail Talon / Terra Ultra / Trailfly shoes - have been running in these for years and I have stocks for the years to come. So I was really excited to try this pack from Inov8 as well - I was looking forward to the side positioning of the bottles (the only thing that I actually like on the pack in the end), the horizontal attachment of the poles at the back and the versatility with the attached large compartment. Now the pole attachment on the back is of no use for me as the poles are bouncing and hitting my back when the pack isn't loaded much or pressing against my spine unbearably when the pack is loaded. Speaking about loading - if the large compartment is loaded with more than 1.5kg it is bouncing like crazy and it keeps coming off the sliders on top ( I didn't manage to fix any of these in any way by pulling the adjustment straps). One other annoying thing are the valves on the bottles - they're not very easy to pass through the attachment loops and often come off the tube, resulting in water spills. All in all this pack is really a huge let down. 100+ quids down the drain : (
