Ergonomic Design


Ergononomic design is important for both the baby being carried - and also the wearer doing the carrying. 

All too often - babycarriers are designed with only the comfort of either the wearer or the passenger in mind. 

The JACS has been designed to make sure that the babycarrier system is comfortable and supportive for both.

Babycarrier Unit:

Our babycarrier component offers a wide seat base - giving good knee to knee support during the essential first 6 months for babies, when a babies hips and sockets are still developing. The design, materials, and construction of our carrier unit provide a structured seating position with less flex and stretching of the fabric - ensuring that the carrier unit does not distort or buckle when loaded.


Check out images of some of our JACS Customers on our JACS In Action page (click link) to see just how much support our babycarrier gives in any carrying position.

This support continues long after the first 6 months. We have also introduced height adjustable attachable footrest stirrups to the JACS range - which integrate seamlessly with the harness and carrier unit in both front and rear carrying positions - to provide additional leg and hip support for growing babies and toddlers.

Harness Component:

There's a very good reason that military load carrying gear is designed with a wide harness or yoke.

That reason is to spread the weight of the load being carried - so the wearer can carry more, carry longer, and grab what they need when they need it.

We've taken those basic principles - combined with our experience wearing load bearing gear during our own military service - and built them into the JACS Harness design.

It's simple really!

If you design a carrier around a basic X type cross strap system - as soon as you put a load into the carrier unit, all of that weight will be concentrated in a single point .... where the two straps intersect.

The cross straps will typically ride up the wearers back, and the straps pull together at the natural point of least resistance - at the wearers neck. The more weight that is applied to the strap ends - the more this movement is likely to happen.



Or if you design a carrier like a backpack worn on the front - with shoulder straps and a hip belt - the majority of the weight will be distributed down towards the wearers hips, and at the shoulders (pulling them forward).

With a JACS Harness - all of this weight is distributed evenly across the wearers torso, through the back and shoulders. This effectively spreads the load - making the JACS more comfortable to wear for longer, even with more weight applied .... letting your adventures continue further than some other types of carrier.


And thanks to the modular design - when you integrate the backpack on the rear of the harness (or front, when using the back carrying position) - the load is counterbalanced ..... which helps to avoid additional stress and strain on your back. 

The JACS has been safety tested and certified to EN 13209-2:2005 standards.
