Breathing and Snoring Solution for Sleep

This backpack provides comfortable back support to help you sleep on your side so that the tongue, soft palate, and relax throat tissues will not fall backward, blocking the respiratory tract and inducing sleep disorder and snoring. The unobstructed airway will allow you to breathe smoothly while sleeping. This product can only help with trouble breathing and snoring caused by supine sleep position. Please try our Nasal Dilator or Mouth Strips for snoring caused by nasal congestion or mouth-breathing.

Develop the Habit of Side-Sleeping

Research shows that 80-85% of snorers only snore while sleeping on their back. Supine sleep position causes the tongue and soft throat tissue to collapse into the airway, obstruct breathing, and lead to snoring. That is why snorers are often told to sleep on their sides rather than on their backs.

This product helps maintain side-sleeping position naturally. When the habit of side-sleeping being developed, most users no longer need to wear it every night. It works in perfect combination with our Mouth Tape and Nasal Dilators to relieve snoring!



Big Enough to Ensure Side-Sleeping

This backpack is big enough and keeps you off your back at night. Imagine what will happen if the back supporter is small or flat. You will end up sleeping on your back with it pressing on your spine, which is not just painful but dangerous.

Stable and Comfortable at Night

This backpack features a three-point fixation design at both shoulders and waist, which disperses the pressure of the fixing straps to ensure a comfortable and stable support. Imagine what will happen if it is fixed around your chest with only one strap (especially for women) or placed in a back pouch of a pajama. It will shift and slide around over time, allowing you to roll onto your back.


All buckles have been replaced by magic tape to prevent slipping out and discomfort. The connection at the root of the shoulder strap and the zipper of the backpack have been enhanced.


Two Ways to Wear for Comfort

You can choose the most comfortable way to wear with our patented two-magic tape design.

A. Fasten the straps across your chest with the first magic tape.

B. Fasten the straps across your shoulders with the second magic tape.

Portable and Washable

The backpack is very light and can be inflated by mouth. The deflated backpack is foldable, portable, washable, and ideal for travelling. It can withstand regular washing and long-term use.

Size Guide

Two sizes are available. Choose Large if your back width is more than 16 inches or 40 cm. Otherwise choose small. If your back width is between 14 1/2 and 17 inches (37 and 43 cm), choose large for full side-sleeping or small for half-to-full side-sleeping.

Size Adjustable

Additionally, you can adjust the air capacity of the airbag from half-full to full to find the suitable size for the best side-sleeping position.
