The N-3B parka, also known as the Snorkel Parka, was developed in the 1950’s for use by Air Force flight crews stationed in extremely cold static areas. The parka was designed for use down to -60 degrees Fahrenheit, with other layers worn underneath. The nickname “snorkel parka” comes from the hood being able to be zipped up to where only a small part of the wearers face is exposed. The parkas are wind proof and are lined with polyester, making them light for the level of warmth they provide. Early versions of the parka (not these ones) were lined with wool and the hoods were lined with real fur. Later production would switch to synthetic lining and wool blends for the hood. The parkas are ¾ length, so they cover past the wearers waist and have a draw string that can be adjusted for best fit around the waist. On the front are four pockets with button snap closure. The parka has a zippered front with a buttoned storm flap for extra protection. This is a great jacket for the coldest days when outside working or just walking around town.

Used have some discoloration from long term storage! Please note these are NOT waterproof.

  1. Hickerbilly (verified owner)

    Mine came in today I don’t believe this parka was ever issued! Even the insides of the pockets showed nothing clean as a whistle!! The jacket even had thread ends just laying on it wish I had more money I would buy a few more!!!

  2. Chase DeCroo (verified owner)

    Used? More like brand new with tag!

    • Jeff Radspinner

      the “used” have some super light fading on the backs of them. You have to look really closely to see it. I don’t think the jackets in this batch have ever been used before though.

  3. Jeff long (verified owner)

    Package arrived today on time and the contents is as advertised

  4. Donald Mantha Jr (verified owner)

    I bought this used and it’s more like NEW. I think it was issued once all i found was a pair of packaged ear protection foam plugs in a pocket. Nothing wrong with this parka…it’s perfect.!!!!!

    Mine came in today…Excellent delivery time…ordered on a Sunday night, arrived on Thursday morning…As previously mentioned by other reviews I don’t believe this parka was ever issued. In my opinion it’s in pristine condition all the way around…Well packaged…I plan to purchase another shortly.

    Asked by KJ on December 20, 2021 8:48 am

    yes, the chest size is the same on the small and medium parka. The difference between small and medium is the length of the parka and sleeve length.

    Asked by Tyrone Lenox on October 19, 2021 8:00 pm

    The chest size (54") should fit just fine over a sweatshirt but the length will probably be an issue especially on the sleeves :(
