I like to use it to hold grocery bags going upstairs too. Very convenient parent gadget.

These were purchased for international travel. They were perfect for attaching that one last thing to my carry on bag.

It was great for that sweater/light coat that you didn't need yet, but know you'll need after sunset.

They adjust really well and give you more length options than some of the other brands.

The only semi-drawback was the metal clip is a circle. This made it slightly more difficult to clip on some bags, but it's a minimal issue.

These were so loved during our journey that I ended up gifting them to a friend whose travels were still going to Portugal, Scotland, and more! This friend lives on their sailboat (I know!) so they carefully consider every item they take onboard, and these were deemed worthy :)

I thought this was a bit gimmicky but I fell for it and gave it a try. I was pleasantly surprised! One wears layers when traveling and I usually run hot. However I still need to carry a jacket for the cold planes or destination etc. I usually tie it around my waist (ugly I know) as a last resort or tuck it madly into my bag. I clipped this to my backpack and it held my jacket perfectly! Easily accessible and the jacket never drug or fell. It also worked well to clip my backpack to my luggage while in between flights. I haven't tried the bag to bag attachment option yet but I don't see why that wouldn't work as well.
Thank you! This is part of my essential travel items now.
My only negative is the buckle is a bit finicky but works fine. You have to push it further into the female end more than normal. Making you think it's broken at first but it is not.

My spouse wanted these for her handbag and backpack when she goes on a trip. She likes them.

I used it on my cross over purse. To hang my coat. Works great.
