What is the age range for using the JACS Baby Carrier?

The JACS can be used with babies from 3 months old, up to approximately 3 years of age. The back-mounted baby-carrier position is suitable from around 9 months, or when your baby can hold their head unsupported.

Is the JACS safe?

Yes. The JACS has been designed to meet or exceed all requirements of the European safety regulation EN 13209-2:2005, and has been independently tested and certified by Bureau Veritas.

Is the JACS ergonomic?

During our development of the JACS concept, we carried out extensive research to ensure that the design was suitable and safe. We have followed the advice and recommendations of several organisations that have provided input into topics such as babycarrier design, including the International Hip Dysplasia Institute, and have incorporated these into the the JACS where necessary.

The design of the Babycarrier component allows the JACS to have a wider range of carry positions and functionality than typical wide-base carriers that can often only be used for inward facing or front carrying only.

The JACS has been designed to offer a wider seat base than most multi-positional babycarriers, and has an 18cm wide seat as standard. The carrier unit provides a more structured and well supported seat than other carriers, due to the materials used in manufacturing - and coupled with design elements of our product - the carrier seat base is less prone to stretching and distortion, and provides a great deal of support for a carrier of this type. Dependent on the age/size of the baby being carried, this will provide a good degree of knee to knee support. As the child grows, the degree of support provided will decrease.

We are also developing a range of accessories, and have recently added height adjustable attachable footrest stirrups to the JACS product range. These provide a greater degree of leg support for older/larger babies and children, as they grow. These can be attached using the front and rear mounted D-rings on the harness, and will provide additional leg support for the child, while also maintaining an M seating position. A wider seat base infant insert is also in the pipeline.

How many carry positions does the JACS have?

There are three carry positions for the babycarrier component, dependant on the age of the baby or child. Front inward facing, front outward facing, and back-mounted. The JACS Baby-Carrier can be either front or back mounted, using the mirrored connection platform on both the front or rear of the harness.

The JACS Babycarrier component features a ventilated head rest that provides full head and neck support for younger babies when being carried in the front mounted inward facing position, and also provides extra support while back carrying older babies and toddlers. The headrest can be folded down when carrying babies in the front outward facing position, once they have reached a suitable stage of development and are able to maintain independent head support. The removable 100% cotton babycarrier liner also doubles as a built-in dribble bib for front carry outward facing travel.

With up to 12 different component configuration options to choose from, dependent on the package option, you can set up your JACS to suit you and your child. As well as babycarrying, you can also use your JACS for a wide range of outdoor activities that don't involve having a little person strapped to you. Simply configure the harness, backpack, and chestpouch components to suit your needs, or use the backpack on its own.

What is the weight limit of the JACS?

The JACS can comfortably carry babies/children up to a maximum weight of 15kg (33 lbs). Each individual connection point is designed and tested to carry in excess of 20kg.

I'm Quite Tall/Short - will the JACS fit me? 

The JACS Harness has been designed to fit the average male torso, and can comfortably be worn by users between 160cm and 185cm in height (approx. 5’4” to 6’1”), with a waist to shoulder measurement of between 50cm and 75cm (20"-.30"). We are planning on introducing under-size and over-size harnesses for shorter/taller frames in the near future. All standard-size attachable components will be able to connect to these non-standard sized harnesses without modification.

The JACS harness is fully adjustable for width, using the two side straps. These allow for a waist/chest adjustment from 32" to 54", with additional adjustment available using the chest strap, to create a more tailored fit after adjusting the side straps. The best fit is for the harness side straps to sit below the ribcage, to allow for the straps to be tightened to reduce harness slippage when load bearing. To minimise this, it also helps if the chest width is slightly wider than the waist.

How do I clean my JACS?

The removable baby carrier liner can be machine washed at low temperature, using a mild detergent. The outer surface of all of the JACS components and associated accessories can also be spot cleaned using a soft damp cloth and mild detergent. The JACS can also be machine washed at low temperatures, using a mild detergent, and air dried. We recommend that the JACS is placed in a pillowcase, or other fabric or mesh bag, and any Karabiners or other detachable connections removed prior to washing, in order to avoid any damage to any of the components or the interior of the washing machine.

Where can I buy the JACS?

Currently, the JACS is only available to buy online via the www.jacs-babycarrier.com website. This allows us to personally inspect each product prior to dispatch, to ensure everything meets our exacting standards. It also means that if you buy a JACS from anywhere else, advertised as new, it will not be a genuine product - as we do not sell via third party sellers or distributors.

Do you ship internationally?

Yes we do. Free shipping worldwide is included in the price of your JACS package, and is standard for all orders over GBP £50.

So far, we've dispatched JACS orders to over 28 different countries around the world.All orders are sent using Royal Mail's Domestic or International Tracked and Signed For service. Depending on the shipping destination for your order, it may not always be possible to track your packages progress once it has left the UK, as Royal Mail tracking reference numbers may not be recognised by some domestic postal services.

My child has outgrown the JACS – Can I still use it?

Yes you can. The JACS has been designed to have a second life both during and after baby-carrying duties. The harness, backpack, and chest pouch, plus other accessories, can all be used in a number of different set-up configurations for a variety of activities such as hiking, cycling, climbing, and much more. The standard 12 litre backpack can also be used as a stand-alone daysack, using the adaptor straps provided.

What accessories can I buy for my JACS?

As well as additional removable liners for the baby carrier, plus the optional chest pouch and back-carry straps, we are working on introducing a range of accessories that complement the JACS design. We welcome any suggestions for modifications to the current product range, or additional JACS product ideas, in order to be able to offer a versatile product that meets the needs of JACS users.

Can I order a custom/bespoke colour option?

Why does my order confirmation show an estimated dispatch date?

We're an independent small business, so we're currently only able to produce the JACS in small batches. This sometimes means that we might temporarily be out of stock in between production runs - although we try to avoid this where possible. You can still pre-order a JACS via the website, and we will dispatch your order as soon as the new stock arrives.
