Rothco ECWCS Gen III Level II Crew Top Base Layer

The Rothco ECWCS Gen III Level II Crew Top is a men's mid-weight grid fleece base layer built for cold-weather military, tactical, and outdoor use. Constructed from a 93% polyester / 7% spandex blend, the long-sleeve crew neck wicks moisture, resists odor, and layers under mid- and outer-shell garments in the Extended Cold Weather Clothing System. Available in Black in sizes S through 3XL.

Built for Cold-Weather Layering

The Rothco ECWCS Gen III Level II Crew Top uses a mid-weight grid fleece construction specifically designed to sit next to the skin as the first layer in a cold-weather system. Grid fleece traps warm air in its open-cell structure while remaining light enough that adding a mid-layer or shell on top does not create bulk that restricts movement. This makes the top practical for extended wear during winter operations, patrol, or outdoor activities where temperature management matters more than any single heavy garment.

Moisture Wicking and Antimicrobial Defense

The 93% polyester / 7% spandex fabric actively moves sweat and moisture away from the skin and transfers it outward to the next layer, where it can evaporate. Staying dry against the skin reduces the chill that wet fabric causes during rest periods or when activity levels drop. The antimicrobial treatment works alongside the moisture-wicking construction to limit odor buildup during multi-day field use, camping trips, or back-to-back cold-weather shifts.

Fit Details That Stay Out of the Way

The 7% spandex content gives the grid fleece enough stretch to move with the body rather than binding at the shoulders or elbows during crouching, climbing, or carrying. An extended back tail maintains coverage when bending forward or low-crawling, so the lower back does not become exposed to cold air. Thumb holes at the cuffs anchor the sleeves in place when pulling on a mid-layer or outer shell, preventing the base layer from riding up the forearm.

Who This Is For and Isn't

The Rothco ECWCS Gen III Level II Crew Top suits men who need a moisture-wicking, antimicrobial cold-weather base layer for military service, tactical operations, or outdoor activities such as hiking, hunting, skiing, snowboarding, and camping. It is designed to be worn as the first layer in a multi-layer cold-weather system and works with matching ECWCS Gen III Level II Underwear Bottoms for full lower-body coverage.

This top is a base layer garment only and provides no ballistic, stab, or impact protection. It is not a standalone cold-weather solution and is intended to be worn under additional mid-layer and outer-shell garments in cold conditions. This SKU line is sized for men only.

Common Questions

What does "ECWCS Gen III Level II" mean?

ECWCS stands for Extended Cold Weather Clothing System, a layered military cold-weather clothing standard. Gen III is the current generation of that system. Level II is the mid-weight base layer position, worn directly against the skin beneath a mid-layer (Level III) and outer shell. The Rothco ECWCS Gen III Level II Crew Top is designed to fill that base-layer role in the system.

What is the fabric composition and why does it matter?

The Rothco ECWCS Gen III Level II Crew Top is made from 93% polyester and 7% spandex. The polyester provides moisture-wicking performance and holds the antimicrobial treatment, while the spandex adds stretch so the fabric moves with the body. This blend keeps the garment close-fitting without restricting movement during active use.

How does the moisture-wicking work in a layered system?

The grid fleece construction of the Rothco ECWCS Gen III Level II Crew Top pulls sweat away from the skin and moves it outward toward the next layer, where it can evaporate more readily. This keeps the skin drier during high-output activity and reduces the rapid chill that wet fabric causes when activity slows or stops in cold conditions.

What sizes are available?

The Rothco ECWCS Gen III Level II Crew Top is available in Black in six sizes: S, M, L, XL, 2XL, and 3XL. Select the size using the variant selector on this page.

Can this top be worn as a standalone shirt?

The Rothco ECWCS Gen III Level II Crew Top is designed as a base layer to be worn under additional garments in a cold-weather layering system. While it can be worn alone in mild conditions, its mid-weight grid fleece construction is optimized for use beneath a mid-layer and outer shell in cold weather.

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.
