Question 1

. Can the straps be adjusted enough to lower the backpack to fit around the waist line. My wife wants to play golf using it and wants it to fit lower

Accepted Answer

Don’t think that would be a good idea. The weight of the Inogen5 requires it to be strapped fairly snug. Assuming it would have to be on the lower back, in order to perform a golf swing, I would think that could cause bruising to the lower back and tops of the side hips. Depending on the O2 requirement of wearer, the G5 pulsates
As high as 6 liters. As a golfer, I wear the cánula as I ride in the golf cart. When I get out to hit the ball, I take the cánula off, and take deep purging breaths as I go to hit my ball. Having a Blue Flag 
due to my condition, I drive up right to my ball. 
This way it has not been a problem. The backpack is mostly designed for long walks, shopping malls  or lite jogging.

Question 2

Is there a separate compartment big enough to carry two extra double inogen one g5 batteries?

Accepted Answer

No. this is a lightweight backpack. You have 4 pockets in this backpack for keys, wallet, phone, etc. You can put a double battery in side pocket but, not 2.

I recommend this backpack if you want to carry a lot of accessories: https://www.amazon.com/O2TOTES-Inogen-Backpack-Lightweight-Comfortable-Fits/dp/B08375GSHB/ref=sr_1_9?crid=1RF0GBH9UB66J&keywords=inogen+one+g5+backpack&qid=1684426290&sprefix=inogen+one+g5+backpa%2Caps%2C134&sr=8-9&ufe=app_do%3Aamzn1.fos.006c50ae-5d4c-4777-9bc0-4513d670b6bc

Question 3

Does it have a water bottle holder?

Accepted Answer

No it does not have a actual water bottle holder but does have a side pocket which would hold one

Question 4

Does the pink backpack have a side mesh pocket?

Accepted Answer

This one does not. The grey & black do. The new ones in this color which will be out next month (with a lot of premium features not on this backpack) will have the mesh pocket on the side and a few new surprises that will upgrade this backpack. They will be a little more but the features are amazing.

This is the last of these backpacks for now.
