Do you have the 2011/12 Snowpulse FB ProTech Vest? Typically there is a large sticker on the cylinder with all the hazardous materials info as well as general safety info listed on it. Unfortunately, there is no weight listed on the cylinder. If you would like additional information on your cylinder, you can visit: http://www.snowpulse.com/en/rubrique/technologie/cartouche-2/
It is generally a good idea to deploy your new pack once you receive it. That way you are a lot more familiar with how it works. You will have deployed it, repacked it, and had your cylinder filled. After you are comfortable with how the system works, you are all good to go!
