Rothco ECWCS Poly Zip Collar Cold Weather Mid-Layer Shirt

The Rothco ECWCS Poly Zip Collar Shirt is a cold-weather mid-layer built for active duty personnel, outdoor workers, and cold-climate athletes. Constructed from 100% expedition-weight polyester with a soft fleece lining, the shirt delivers warmth without bulk as part of the E.C.W.C.S. (Extreme Cold Weather Clothing System). Available in Black and AR 670-1 Coyote Brown, in sizes S through 4XL (Black) and S through 3XL (Coyote Brown).

Built for Cold-Weather Layering

The Rothco ECWCS Poly Zip Collar Shirt sits in the mid-layer position of a cold-weather clothing system, where its job is to trap warmth while remaining thin enough to wear under an outer shell. The 100% expedition-weight polyester outer and fleece lining combination handles that balance: the polyester resists moisture migration from the outer layer while the fleece retains heat against the body. For anyone spending extended time outdoors in cold conditions, on duty, on the mountain, or in the field, a reliable mid-layer reduces the need to stop and adjust.

Collar That Adapts to Conditions

The zippered collar on the ECWCS Poly Zip Collar Shirt lets the wearer choose between a full turtleneck position for maximum neck coverage and a lower V-neck position when conditions warm or exertion increases. That adjustment takes seconds and requires no additional gear. In layering systems where removing an entire garment disrupts the rest of the kit, a collar vent is a practical temperature-management tool rather than a styling detail.

Secure Fit at the Wrist

Elastic wrist cuffs on the Rothco ECWCS Poly Zip Collar Shirt seal the sleeve against the wrist, preventing cold air from entering at the cuff during movement. For skiers, snowboarders, and anyone working with their arms extended or overhead in cold conditions, a secure cuff also keeps the sleeve from riding up under a glove or outer layer.

Features

  • Expedition-Weight Polyester Shell: 100% polyester outer resists moisture and holds its shape under an outer layer.
  • Fleece Lining: Soft fleece interior retains warmth against the body.
  • Zippered Collar: Adjusts between turtleneck and V-neck positions for temperature management.
  • Elastic Wrist Cuffs: Seal the sleeve at the wrist for a snug, draft-free fit.
  • ECWCS Compatible: Designed as a mid-layer within the Extreme Cold Weather Clothing System.

Who This Is For and Isn't

The Rothco ECWCS Poly Zip Collar Shirt suits active duty military personnel, law enforcement officers, skiers, snowboarders, and outdoor workers who need a reliable mid-layer in cold conditions. The AR 670-1 Coyote Brown colorway is appropriate for wear in uniform contexts that permit that color standard.

This shirt is a mid-layer garment only. It is not a standalone cold-weather outer shell and is not designed to be worn as the outermost layer in wet or windy conditions without an appropriate outer garment over it. It carries no ballistic, stab-resistant, or protective rating of any kind.

Common Questions

What does ECWCS mean, and how does this shirt fit into that system?

ECWCS stands for Extreme Cold Weather Clothing System, a layered approach to cold-weather protection used by the U.S. military and adopted widely in outdoor and tactical contexts. The Rothco ECWCS Poly Zip Collar Shirt is designed as a mid-layer in that system, worn over a moisture-wicking base layer and under a wind- or weather-resistant outer shell.

Can the collar be worn in more than one position?

Yes. The Rothco ECWCS Poly Zip Collar Shirt features a zippered collar that can be worn fully closed as a turtleneck for maximum neck coverage, or unzipped to a lower V-neck position when less insulation is needed. The adjustment is quick and does not require removing the shirt or any other layer.

Is the AR 670-1 Coyote Brown colorway regulation-compliant?

The AR 670-1 Coyote Brown variant is produced in the color standard specified by Army Regulation 670-1. Whether it meets a specific unit's uniform requirements depends on that unit's current orders. Buyers should confirm compliance with their chain of command before purchasing for duty use.

How should the ECWCS Poly Zip Collar Shirt be sized?

The Rothco ECWCS Poly Zip Collar Shirt is available in S through 4XL in Black and S through 3XL in AR 670-1 Coyote Brown. Rothco publishes a dedicated size chart for the ECWCS Poly Top line; consult that chart for measurements before ordering, as mid-layers are typically worn over a base layer and sizing may differ from a standard shirt.

What is the shirt made of?

The Rothco ECWCS Poly Zip Collar Shirt is constructed from 100% expedition-weight polyester on the outer shell, with a soft fleece lining on the interior. No cotton content is stated. The shirt is ISO Certified per Rothco's product data.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
