I've been using a carabiner through the strap to clip my helmet to my backpack. But it seems clumsy, and the helmet dangles around a lot. I've seen other people with helmets closely mounted on a bag. How do they do it? Is there some kind of clip for this purpose?

    You're supposed to hang it from your stem. See rule 76 for more info. :)

    Why bother with a carabiner? Just loop the helmet strap through whatever the carabiner's attached to. This gives a slight improvement in dangle-length over using the carabiner, but I realise you're looking for a bigger improvement than this. Commented Apr 24, 2016 at 22:01

    Lots of bicycle or trekking backpacks have a dedicated helmet holder net.

You can make your own retention system for any bag which will hold the helmet secure and close to the bag. I've done this on a number of my bags as I carry both bicycle and climbing helmets at times and there is never enough space for them inside a bag as they're such awkward shapes.

Buy some elasticated cord (often called shock cord) and some cord locks of an appropriate size for the diameter of the shock cord you have. Threading this through a strap or some webbing on the bag and leaving the cord locks outermost will give you a size adjustable retaining loop that will hug the helmet to the bag.

Alternatively, find something (I've used shaped pieces of wood or plastic) that will fit lengthways through a vent on your helmet, but is too long to fit through the vent when rotated sideways. This becomes your toggle, tie this to the shock cord and you can use a single length (easier and neater to tuck away when not in use) with the toggle at the end. To fasten the helmet, push the toggle through a vent and twist it sideways so it can't fall back through the vent.

EDIT: a video demonstration and a couple of photos for you. Other manufacturers do this, Osprey and their 'lid lock' feature are just the one that came to mind for me to search out images.

  • Gidday and welcome to SE Bicycles. Great first answer. Note you can include photos in your answer, which can make it easier.

I would suggest following - try to clip helmet chin strap around both backpack shoulder straps or, if backpack is not too big, try to clip it around whole backpack. (If your backpack is large enough you can put helmet inside it :). There is also possibility to use rubber strap with hooks to fasten your helmet.

Tbh, I have backpack which has dedicated helmet holder but I rarely use it. I find it much faster to hang it around stem and handlebars. That way it is much faster to put your helmet on compared to taking off backpack, untying helmet and putting it back on.

    If you can clip the chinstrap round the whole backpack, that suggests an extremely small backpack! Commented Apr 24, 2016 at 22:03
  • What do you mean by "dedicated helmet holder"?

  • @ElliottB, for example, on this 40 liter backpack, the piece of fabric, holding the designation and front zipper, is intended for a helmet.

In case of this type of backpack(they seem to start from 25 liters up)

enter image description here

Clip the helmet shut and thread the chin strap through both backpack straps(1, 2). Quick and reasonably steady.

For a short climb, shop visit, water stop - clip the shoulder strap to the plastic ring(3) on the shoulder strap. Almost zero effort.

In my experience both of those methods result in gradual stretch at the buckle of the chin strap, so the helmet needs to be re-adjusted now and then.


I just use the strap with its own clip. It does swing around though.

Some bags have an elastic net that works very well (I have a rucksack that does this but I hardly ever ride with it).

Can you get the carabiner through both sides of the strap? That might help. It might be too tight though. Replacing the carabiner with a strap you can pull tighter might be a good compromise.


Stick on or sew on Velcro fastener on the strap close to the helmet and on a suitable part of the back pack or an industrial size press stud fastener.

Hopefully you do not plan to carry the helmet on your back pack when you are riding

    I'd keep the helmet on for riding, but it wouldn't be unreasonable to ride flat forest trails without a helmet on the way to a downhill, or to take it off for a sunny towpath. The answer the OP is looking for all depends on whether they plan to ride with it clipped on, or only walk.

Most other answers cover mostly the "retrofit" of an existing bag, but if someone is looking for a new bag, it should be noted that many bag-backs manufacturers have specific products for cycling. The "Lid-lock" of Osprey is one example, some have special hooks for the helmet straps (Deuter, Vaude, ...), some have nets (Agu,...)

Bagpacks are products that are still very dependent of the region and products are typically "seasonal", so listing the products is a bit futile for the format of the site. But it may be worth noting that "cycling commuter" is a category that is growing, and helmet holders, light mounts, high-visibility features or a back panel shape more suited for cycling (cyclists usually are more horizontal than walkers) are among the features that differentiate such bag packs from "regular" bag packs.
