The Legend 165 is probably the most comfortable inflatable lifejacket on the market. The Legend vest's unique neck opening design ensures that the vest sits wider over the shoulders and does not press on the neck. This makes wearing the lifejacket significantly more comfortable in the long term, and when you use the vest with a high-necked boating/sailing jacket, for example. Legend vests use a soft and durable surface material that molds to the user's body.

The lifejacket has an inspection window, from which you can check the condition of the vest in an instant without opening the vest.

When the vest comes into contact with water, the zipper tears open and can be closed again when the vest is reloaded and ready for use.

For this reason, the vests are granted a 5-year material guarantee.

The Bambi Supersoft life jacket, specially designed for babies, has incredibly good turning properties, and always turns the child onto his back in seconds to a floating position. The 100N (newton) buoyancy floats the child on the "high" surface of the water, and the child floats safely in a back position. The large floats on the front and in the collar ensure that the child cannot turn face first into the water. The softest Airex flotation material on the market is significantly softer than traditional flotation materials, and the comfort of use is in a class of its own. The large collar supports the child's head even if he is not able to hold it himself, and the lifting handle on the collar is very practical when you have to lift a small child onto the boat from the dock. The diaper-style crotch strap supports the child, and is significantly more comfortable for the child than a traditional crotch strap.

FEATURES:

• Large collar with reflector.
• Fleece lining in the collar.
• Durable and visible high-visibility UV fabric.
• Strong zipper construction.
• Tension strap with quick-release buckle.
• One-piece vest
• A "diaper-style" crotch strap that can be attached with a quick-release buckle in two different positions for the best possible fit.
• Lifting handle on the collar

Replacement cartridge for all life jackets with a buoyancy of 150, 165 and 170 newtons. Baltic is the manufacturer, but this is also suitable for other brands of inflatable life jackets that use a 33 gram CO2 cartridge. For this reason, the package includes three different fastening pins that come off when the vest needs to be inflated. The bottle does not have an expiration date, so it does not need to be replaced every 3 years like the trigger. You can always check the condition of the bottle by unscrewing it from the trigger, checking the gram amount indicated on the side of the bottle, placing the bottle on a digital scale so that the measured weight can be +-2gr from the indicated on the side of the bottle. If the vest is full, the bottle should always be replaced and we recommend always keeping a spare set of bottles and trigger in the boat.

NOTE! The Halkey Roberts pin shown in the picture above is not included in the package.

An inflatable life jacket designed especially for women. The CO2 cylinder is placed horizontally in the vest, while the filling cylinder is normally placed vertically. This placement significantly improves the fit for women as the filling cylinder does not press on the chest and the vest effectively removes weight from the shoulders. The Athena vest has, like the popular Legend vest, a large neck opening, which allows the vest to sit on the shoulders and not press on the neck and allows good mobility in the neck area. Another difference between the Athena vest and other vests is that the quick buckle is placed on the side of the vest, so that the buckle does not come directly to the front, which makes it more comfortable, especially when sitting. In addition to the fit, the vest has first-class features such as a wear-resistant and shapeable outer fabric, an inspection window from which you can check the condition of the vest in an instant without opening the vest. The vest has an automatic United Moulders trigger mechanism, which automatically inflates the vest when it comes into contact with water. Baltic inflatable life jackets are closed on the sides with a durable zipper, which extends the life of the vest. When the vest comes into contact with water, the zipper tears open and can be closed again when the vest is reloaded and ready for use. Baltic life jackets are of very high quality and the condition of each vest is tested separately before being sent from the factory. Therefore, the vests are granted a 5-year material warranty. Color: white/pink.

A life jacket designed for children weighing 3-15kg, with excellent turning properties in the water, due to the design of the vest and the 100 Newton lift that always turns the child on his back to a floating position in the water in seconds.

The collar is divided into three parts, so when in the water it supports the head from three directions and makes it easier to keep the head up.
