Flying with your TeamO lifejacket

Flying with a lifejacket can sometimes be complicated because each airline has its own rules about what it will allow on its airplanes. Many sailors and international jury members travel with their own lifejackets however and we are often asked how to fly with a TeamO, so the aim of this blog post is to help you to prepare for your flight with your BackTow lifejacket.

Aviation industry official line:

According to the International Air Transport Association  (Dangerous Goods Regulations; 27th Addition, published 2016, section ) "small cartridges fitted into a self-inflating lifejacket must be for inflation purposes. No more than two small cylinders of carbon dioxide or another suitable non-flammable non-toxic gas fitted in the lifejacket per person and a maximum of two spare cartridges." In addition to this, you are not allowed to carry more than one personal safety device per person, and the personal safety device must be packed in such a manner that it cannot be accidentally activated.

In practice, this means that CO2 cylinders may be carried as either carry-on baggage or checked (hold) baggage, but we highly recommend getting prior approval of the airline you will be travelling with.

TeamO CO2 Cylinder Specifications:

All of our CO2 cylinders are guaranteed to meet the following specifications:

- Weight: our 170N lifejackets carry a 38g CO2 cylinder. The 275N lifejackets carry a 60g CO2 cylinder.

- Burst pressure: minimum 560 Bar

- Internal pressure: 5,70MPa (at 20°C)

Useful Links (In Multiple Languages for Multiple Countries):

There is a download link to a letter here for TeamO customers which you can print out to present to your airline to confirm these details.

In additional you may like to download and print the IATA guidelines mentioned above. The link to their official guide is here, and contains the IATA Dangerous Goods Regulations Table 2.3.A in five languages (English, German, French, Spanish and Russian) and a detailed description of the CO2 cylinder. We suggest you print a copy of this and put it together with the TeamO letter above and keep it with your lifejacket.

For US travellers you may also want to print out and carry a copy of the TSA 'Prohibited Items' document (link available here) that explicitly permits two CO2 cartridges to be carried with a PFD.

We hope this short guide is useful for sailors traveling with their TeamO lifejacket. If there are any questions we can answer drop us an email at

This life jacket is so light and noninvasive that I forget that I’m wearing it. I highly recommend it!


We received our 170N life vests within two weeks of placing our order. We live in Texas and expected shipping from the UK to take longer. The vests are comfortable to were while on deck. My wife and I are leaving Galveston in April for our years long cruising life and I purchased these life vests because we are expecting to be on watch alone at various intervals. We both clip in our tethers and use jack lines when necessary to go forward while underway.. Neither of us has ever fallen overboard and this is our greatest fear while underway. This vest appears to provide the best possibility for survival if one of us fall overboard while alone on deck.

Few Upgrades and would be Perfect

Now that I worn it for a little while now it’s a really good product! I’m quite happy with it. The only reason I can’t give it five stars is because the leg straps just aren’t beefy enough. I’d like something more substantial to hold on to me if I fall overboard.. These little teeny tiny thin straps will dig into your legs real quick… This is literally the only thing that’s not built to an industrial standard, everything about this lifevest is made for offshore cruising!
