I have 3 suits. All are Adult Universal size 110-330 lb., 6'3" height, girth 48". All are STEARN'S brand and models are as follows;
1) Immersion Suit ISS-590i (Lot/Serial #311073)
2) Cold Water Rescue Suit (Lot/Serial #585136)
3) Ship Abandonment Suit (Exposure Suit)
I don't know the age. They came with a downeast vessel I purchased last year. I had my own suits from my previous boat. My guess is around 5 years give or take a few. They appear to be in good shape... thanks, Pete
