Really nice and it work perfect for what i need it

if you are in the uk on oxygen therapy with ZA type small bottles supplied by boc this bag fits them perfectly seems to be adequately made , and is a 100 percent improvement on the bag supplied by boc . ( beware that because the bottles have a rounded bottom the bag will not stand upright ! )good value at the present price imo.

I have been using this bag for almost 6 months. I thought I would give it a good test run before leaving a review. I bought it after my oxygen supplier (Baywater) gave me one of theirs to use, it was massive and totally useless for the smaller 300 cylinder. This bag is very robust and sturdy. There are plenty of openings and eyelets to feed tubing through. A few extra pockets to hold your phone and keys. The shoulder straps are nicely padded and there is plenty of adjustment to get the bag to fit snug. There are a couple of issues with the design. Ideally it needs a rigid bottom. The 300 cylinders have a round bottom. This means that when you have to take the bag off and place it down somewhere you have no choice but to lay it flat. It all just seems awkward and annoying when you are out and about and trying to swap cylinders over. Secondly the strap and pocket to secure the cylinder is too big. The way the cylinder sits in the bag, the velcro strap has to be fastened close to the neck of the bottle and it is just way too big. A strap with a clip and slide adjuster, or elastic, would have been better. Thirdly, a mesh back would help with air flow. I found during the heatwaves, my back became incredibly sweaty and uncomfortable as there is no breathability. Finally, after managing to arrange oxygen supply whilst on holiday I was unable to fit the holiday suppliers (Air Liquide) 300 cylinders in the bag. For some reason they had the much bulkier grab handle type valves on them and I could not close the bag. If you have this type of cylinder this bag will be of no use to you. All in all, this is a good quality bag. It will hopefully last a while. It would be nice to see a slightly modified version on the market. I wish companies would ask services users to test products so that they could produce something perfect.

This bag is perfect for my oxygen bottle. It is well made and as good padding for your shoulders and comfortable to wear. Plenty of zipped pockets for phone, purse etc and mesh pockets for water bottles or travel mugs.

The ruck sack has a high quality finish and is perfect for 2 litre oxygen cylinders. There is a separate pocket inside with a velcro strap for securing the bottle. There are exit points for tubes on both sides protected by metal eyelets. There are plenty of additional pockets for phone and water bottle etc. The straps are well padded and adjustable for carrying over shoulder or in middle of back.

This is the perfect size for my LOX flask.I’m very happy with and its well made. I can go for a walk and forget it’s on my back. So I recommend it. Value for money: well the 4 stars instead of 5 rating is because I just think it was overpriced for what is really just a slim rucksack.

Good item

Very happy with bag. It has plenty of room and good quality. It does the job
