Update April 2023

The manufacturer of the popular Dual Band Chinstrap has now added a cheaper version of their chinstrap called the 'Plus' and has re-named the original one to the 'Premium.' The difference is that the cheaper one is made of 100% Indian Manta Cotton which is a high quality breathable cotton material. This does not affect the way this vertical lift chinstrap works, but due to the number of components needed being lowered from 21 for the Premium Chinstrap to 15 on the new Plus Chinstrap, it is cheaper to manufacture. The Dual Band Premium will obviously be the more luxurious of the two!

The image below shows the difference between the Plus and Premium:-

Hope2Sleep's Observations:-

We're pleased with the feedback both via our genuine website reviews and directly to us at the charity since we've been selling the original Dual Band Chinstrap. There will, of course, never be a chinstrap (or any other product) that will suit everyone, but just like masks, getting the 'right' chinstrap is a challenge - especially as most chinstraps tend to pull the jaw backwards which defeats the object of wearing a chinstrap, as it is supposed to encourage the mouth to stay closed without  causing discomfort and jaw pain. The unique vertical lift of keeping the jaw supported and aligned is the unique selling point of these chinstraps.  However, it is crucial to measure for the correct size so please scroll down the page for the sizing chart. The only drawback is this will not suit people with a latex allergy!

• The Dual Band Chinstraps hold and support the jaw in the correct position to ensure the jaw does not recede further back (like other chinstraps can cause, and especially with people who already have a receding chin).
  
  

• Due to the jaw being correctly aligned, it should help prevent a gap forming at the lips and air escaping which can affect the actual CPAP or non-invasive ventilation therapy and also cause disturbed sleep.
   

• The vertical lift will help prevent mouth breathing with the consequent dry mouth this causes, and nasal breathing will be encouraged (although anyone aiming to nasal breathe must also make sure this is comfortably possible and address any nasal congestion, as healthy nose breathing can only be achieved with clear nasal passages).
   

• Another benefit for having the jaw aligned correctly is that it is less likely to cause jaw discomfort which can even lead to pain to the Temporomandibular Joint (TMJ).
   

• An added bonus we discovered when testing, is that due to this chinstrap needing a cap for stability and the mask headgear going over the top of the cap, it should also help people who get discomfort from the mask headgear straps - most of which will be no longer in direct contact with the head or skin.  In fact, we tweaked it and placed the cap further back so that the back neck strap of the headgear also went over the cap material.  Therefore, the CPAP headgear can go either underneath or over the top of the chinstrap.
   

• The Dual Band Chinstrap is also suitable for snorers who are not diagnosed with sleep disordered breathing, to be used without a mask.
   

• There are 3 sizes in both the Plus and Premium versions to allow for the perfect fit.

Hope2Sleep Charity's Testing Results

The following chart shows some testing carried out with a CPAP user wearing his full face mask who is on good therapy with an AHI (apnoea hypopnoea index) of below 5, but leakage was not in good control.  As you can see on the left of the chart, the leakage was fairly high. 

The CPAP user then used the original Dual Band Premium Chinstrap (previous chinstraps tended to cause more leakage with this patient due to his jaw receding further with other chinstraps on).  He changed to a nasal mask but with little 'hope' tried the Dual Band Premium Chinstrap. Much to his delight with the nasal mask and Dual Band Premium Chinstrap his AHI lowered to less than 1 breathing event per hour and no leaks were recorded (see right of the chart). 

Not only does he feel better during the day due to nasal breathing, he has now ordered a nasal mask from his clinic due to the positive change in his therapy.

This was an amazing test for this CPAP user, and in no way are we implying it will be the same for everyone, but we were too encouraged by it not to share.​

Knightsbridge Sleep Solutions say:-

The Reason for the Invention of this Dual Band Vertical Lift Chinstrap vs Traditional Chinstraps:

Traditional chin straps come in two varieties, linear and split. Both work on the same principle. They are made of a single elastic material (usually neoprene) and wrap around the tip of the chin. Notice the straps wraps around the tip of the chin and the force is directed towards the ear, and the jaw joint is located just in front of the ear. So almost all the force applied by a traditional chin strap is directed into the jaw joint.

Traditional chin straps are intended to immobilise the jaw by increased friction in the jaw joint. This is problematic since sufficient force can be painful and long-term use can cause damage to the joint. What is needed is an upwards force, but almost none of the force applied by traditional chin straps is useful in rotating the jaw upwards.

REVOLUTIONARY SUPERIOR DESIGN - Effective and Comfortable

• DUAL BANDS:  Non-elastic blue band prevents jaw from lowering. Elastic white band provides gentle upwards force. Compound elastic and non-elastic force allows pressure to be minimized whilst still effective.
   

• VERTICAL LIFT:  Bands lift from under jaw and attach at the temples to produce vertical force.  (Unlike standard neoprene chinstraps which wrap around the tip of the chin and push the jaw directly into the jaw joint.)  Vertical lift works with the natural rotation of the jaw.
   

• COMFORTABLE, WASHABLE, LIGHT AND BREATHEABLE.

• Finally stop or reduce snoring or CPAP mouth leaks.
   
• Get the restful, restorative sleep you need!

Mesh Cap Material on the superior Premium version only

• The elastic and non-elastic straps produce a compound force curve that allows the pressure to be minimised.
   

• Since a full cap is required to balance the vertical forces at the front, and because it needs to fit heads of various sizes and shapes, the cap is constructed of three panels and has a rear size-adjustment strap.
   

• Due to the cap and a portion of the Velcro (which is a somewhat stiff material) covers the ears, there is an interior soft grey felt lining to make that comfortable, and to provide comfort for wear over months or years, the entire perimeter of the cap is also lined.

Usage Tips:-

TEETH GAP
Many people find it most comfortable to leave a gap between the upper and lower teeth such as you normally have when awake and your mouth is closed and jaw relaxed. The Knightsbridge Dual Band is unique in that it can be easily adjusted to achieve this. To do so use two hands (one on the strap, one on the cap) to attach the blue non-elastic band so it is fairly snug, and then add just the slightest additional force via the elastic band.

STRAP PLACEMENT
Pass the straps under the jaw near the front of the jaw, and attach the straps near the front of the Velcro patch. This provides the most vertical orientation of the lift.

TEMPERATURE
The three layer net-mesh of the Premium Dual Band Chinstrap and the breathable indian manta cotton of the Plus Dual Band Chinstrap are designed to provide a cap which is light and breathable, this will inherently result in some degree of heat retention so it may, therefore, be helpful to slightly lower room temperature or blanket thickness. Ensure that your bed clothes are also made of a breathable fabric (this is advisable for controlling body temperature with or without this chinstrap).

NASAL DILATORS AND NASAL STRIPS
Nasal dilators are devices that are placed in the openings of the nose to widen the air passage, and nasal strips also help widen the passage by placing on the nose - thus make nasal breathing more comfortable, so worth considering when using this chinstrap. The nasal strips work better than dilators with a CPAP mask and the nasal strips we supply at the charity contain no latex. A natural nasal spray like Sterimar, which can be bought in the chemist, can also help with nasal congestion. It is not advisable to use many over-the-counter nasal sprays as most should only be used for a short time or they can make things worse - especially when trying to come off them, which is known as the rebound effect. Please read the labels.

The Dual Band Chinstrap Premium (original) comes in either White or Black and is available in 3 sizes - Medium, Large or XL.

ORDERS

Shipping

We try our best to ship all orders received by us Monday-Friday on the same working day if received before 12 noon, and more often than not orders processed before 3pm will be despatched the same day whenever possible.  Weekend or UK bank holiday orders are sent out the next working day.  An automated email is sent when products have been despatched so please check your spam box and add us to your safe senders list.  Also, if you do not receive an email confirmation, please check that you have typed the correct email address in your account.

All orders are sent via 1st class mail within the UK.  Masks and some other more expensive products are always sent via 'signed for' insured delivery and cannot be left in 'safe' places, but there is the option for an alternative shipping address when processing the orders. 

Delivery charges are worked out automatically by weight and you can clearly see the delivery charges before making a payment.  On the rare occasion delivery charges are miscalculated by the website, a refund will be sent, as it is not our policy to make money on postage charges and neither do we add the cost of delivery into the price and offer so-called  'free delivery' like some sites and Ebay pressurise sellers to do! 

Wherever possible with larger parcels, we try to re-use boxes to keep shipping costs down and protect the environment.

If a product is out of stock and the order contains multiple items, the 'in stock' items will be sent immediately and further items will follow upon arrival with no further postage charges incurred.  

Important for International Orders

We can ship most products internationally, but all prices are in UK British Pounds and if paying by debit or credit card the bank will automatically convert to the current conversation rate.  Likewise, if you choose the Paypal option, they will convert into your currency for you as payment is made.  

International orders are sent via tracked Airmail, and whilst we're happy to ship internationally, we cannot be held responsible for any delays at Customs at your end, or charges that may be added in your own country, such as customs fees and import tax on delivery, which are determined by your country’s import laws and are beyond our control. Therefore, it is the customer’s responsibility to pay these charges, and certain courier companies will not be able to deliver the goods to you without pre-payment of any charges. From our experience, it appears to be randomised as to which parcels incur extra charges, but please know that all accompanying paperwork is filled in correctly when shipping and there is nothing more we can do, as much as we'd like to.

If you purchase from us out of the UK or you move to another country after purchasing products, please be aware that the warranty for CPAP machines, masks and parts from the manufacturers are under warranty  with the manufacturer based in the UK, so you will be responsible for sending the product back to us and will need to pay postage to get the product back to you after exchange or repair, as the manufacturer will not pay for shipping in any country outside of the UK.

RETURNS

Masks, CPAP machines and and most other products are exempt from a refund or exchange unless faulty due to health and hygiene issues - as stated in our 'Terms and Conditions', and in particular due to the risk of cross contamination as they cannot be re-sold. The Consumer Contracts Regulations 28.(3)(a) confirms exemption as follows:-  "exemption in the case of a contract for the supply of sealed goods which are not suitable for return due to health protection or hygiene reasons, if they become unsealed after delivery."

Unopened (sealed) products in their original packing can be returned within 14 days for a refund of the product cost, but the purchaser is to pay the return postage, and we would advise retaining proof of postage. This excludes any faulty goods, for which postage will be reimbursed.  A full refund for the price of the product will be issued when received by us, less the original postage charges when the order was sent to you.
