adidas by Stella McCartney bum bag: the bag I take on every hike

Yes — it comes on every hike with me and most ordinary days too: phone, SPF and lip balm right in front of me, hands free, and it stays put when I move. The only thing I don't love is the very long strap, which I tuck away. 4/5 at around $55.

I take this on every hike

This bum bag comes with me on every hike. Inside I keep my phone, my SPF and my lip balm — the things I always want with me. Having them right there in front of me is so comfortable. I don’t need to stop or take anything off to reach them.

What I like

It is very easy to put on and to adjust. It sits comfortably and stays in place when I move. My hands stay free the whole time, which is what I want on a hike. And it doesn’t only look sporty — I wear it every day too, with normal clothes. I also like that it is made from recycled materials.

The one annoying thing

The strap is pretty long. When you close it, there is a lot of extra strap. In the beginning this annoyed me. Now I just tuck the extra part away and it is fine — but be ready for this.

Who it is for

Good for anyone who wants their hands free and their things easy to reach — for hiking, for travel, or just for the day. Maybe not for you if you carry a lot, or if a long strap would really bother you.

My verdict

I use it all the time and it makes hikes so much easier. The long strap is the only thing I don’t love, and once you tuck it away it’s a non-issue. For me, it is really worth it.

One note: mine is an older version of this bag. adidas releases new versions of the Stella McCartney bum bag each season, so if you want one, just look for the newest version — the colours and details change a little, but the hands-free idea is exactly the same.

Quick questions

What fits inside the bum bag?

My phone, my SPF and my lip balm — the important things. It is small on purpose, so it is not for carrying a lot.

Is it comfortable for hiking?

Very. Everything sits in front of me, it stays in place when I move, and my hands stay free the whole time. I take it on every hike.

What is the annoying part?

The strap is pretty long, so when you close it there is a lot of extra strap. I just tuck the extra part away and then it is fine.

Is it worth the price?

It is a bit expensive for a bum bag, but I use it all the time — on every hike and every day with normal clothes too. For me it is really worth it.

What is the adidas by Stella McCartney bum bag made of?

The outer shell and lining are both 100% recycled polyester, with a polyurethane inner and padding. It's part of adidas by Stella McCartney's more sustainable range.

How big is it and how do you wear it?

It holds about 2.75 litres — compact, made for your essentials. There's a zip main compartment plus front and interior zip pockets, and the adjustable strap means you can wear it on your waist or crossbody.
