Item Sizing Origin & Construction Mike's Notes

American Trench partnered with Cockpit USA to produce this limited run of the iconic N3B Snorkel Parka.

We love the N3-B. It's very much in keeping with the Epaulet principles. It's practical, stylish, timeless, hard-wearing, and can be dressed up or down. It's often made, but very rarely made well - especially these days.

Make no mistake, this is a hardcore winter jacket. Something that can take on the absolute worst of the season - we're talking tundra-ready. It's made in collaboration with Cockpit USA, a military contractor who has been churning out tough-as-nails outerwear for the armed forces, and civilians, for over forty years.

The collaborative N3B Snorkel Parka features one of Cockpit's most classic silhouettes, done up with best-in-class materials throughout.

The shell is made from weather-resistant, 100% cotton rip-stop Ventile. The body uses military-grade synthetic down from Primaloft for the insulation. And the hood has real American coyote fur on the trim, which can be removed for cleaning.

Pound for pound, we genuinely believe this is one of the finest winter coats money can buy. It'll keep you warm, dry, and looking great, for decades to come.

Measurements & Sizing
Note: All measurements are shown in inches. "Chest" is measured from one armpit seam to the other. "Inner Sleeve" is measured from the armpit seam to the end of the cuff. The "Outseam" is measured from the estimated shoulder seam to the end of the cuff. "Shoulder" is measured from one shoulder seam to the other.   "Length" is measured from the base of the rear collar to the bottom of the garment.
*Note - the sleeve is raglan so the yoke and outer sleeve length are an estimated measurement.

This special edition N3-B runs a bit roomy. For example, if you take a 38 in our Southwick sportcoats, then order this piece in a size Small.  Due to the thickness of the coat, the actual measurements make it seem a bit larger than it actually is.
If you stick with this sizing advice, then it should work out great: 
Epaulet shirt Small = Southwick 36 = Snorkel Parka Small.... and so on.

Sixty years ago, the USAF N3-B jacket was created to provide lightweight warmth for flight crews stationed in extremely cold temperatures. Its high-zip neck and padded hood earned it the nickname "Snorkel Parka." Over the decades, it's evolved from a military piece and staple item of Army-Navy surplus shops into a mainstay of classic style.

When the temperature gets cold and nasty, there are few garments which are more faithful than the N3-B. Wear it with jeans and boots for an effortlessly rugged look, or pair it with a suit and dress shoes as a mod overcoat with some attitude. Rain, snow, wind, and sleet, are no problem. And you can expect this to endure for years to come. We're thrilled to present this perfectly executed take on an all-time classic mens outerwear piece.
