The Rothco ECWCS Gen III Level II Mid-Weight Underwear Top is a long-sleeve thermal base layer built for cold-weather military, tactical, and outdoor use. Constructed from 97% polyester and 3% spandex grid fleece, it wicks moisture, resists odor, and layers cleanly under mid- and outer-shell garments. Available in Black, AR 670-1 Coyote Brown, Olive Drab, and Desert Sand, in sizes XS through 4XL depending on color.
Moisture Management When It Counts
The Rothco ECWCS Gen III Level II top pulls sweat away from the skin and transfers it outward toward the next layer, where it can dissipate quickly. In sustained cold-weather activity (a long patrol, a backcountry hunt, a day on skis), staying dry against the skin is what keeps warmth consistent. The grid fleece construction creates air pockets that insulate while still allowing vapor to move, so the top does not trap moisture against the body during high-output movement.
Fit That Moves With You
The 3% spandex content in the polyester-spandex blend gives the grid fleece enough stretch to flex with the body rather than binding at the shoulders or elbows during crouching, climbing, or gear-laden movement. The extended back tail maintains coverage when bending forward or squatting under load. Thumb holes at the cuffs anchor the sleeves in place so they do not ride up inside an outer layer, and the zip collar can be opened for ventilation or closed and worn as a turtleneck for additional neck coverage in wind.
Anti-Microbial Treatment for Extended Wear
The ECWCS Gen III Level II top includes anti-microbial and anti-odor treatment built into the fabric. For military personnel or tactical professionals who may wear the same base layer across multiple days in the field, this treatment reduces odor buildup without requiring a wash between uses. The same feature makes the top practical for multi-day camping, hunting, or backcountry trips where laundry is not an option.

Who This Is For and Isn't
The Rothco ECWCS Gen III Level II top suits military personnel, law enforcement, and tactical professionals who need a cold-weather base layer that meets ECWCS system layering standards. It also works for outdoor enthusiasts (hikers, hunters, skiers, snowboarders, and campers) who want a moisture-wicking, odor-resistant thermal shirt for sustained cold-weather activity. The size range (XS through 4XL across colors) accommodates a wide range of builds.
This is a thermal base layer top only. It provides no ballistic, stab, or slash protection of any kind. It is not a standalone cold-weather garment; it is designed to be worn as the innermost layer under ECWCS mid- and outer-shell components. Size availability varies by color: Desert Sand tops out at 2XL, Olive Drab at 3XL, and Black and Coyote Brown extend to 4XL.
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. Level II is the mid-weight insulating layer, worn over a moisture-wicking Level I base and under heavier Level III, IV, V, VI, or VII shells depending on conditions. The Rothco ECWCS Gen III Level II top is designed to fit within that layering system.
What is the fabric, and how does it perform in the cold?
The Rothco ECWCS Gen III Level II top is made from 97% polyester and 3% spandex grid fleece. The grid structure traps warm air for insulation while remaining breathable enough to transfer moisture outward during high-output activity. The spandex content adds stretch so the top moves with the body without restricting layered gear worn over it.
Does the top have any odor or moisture management?
Yes. The Rothco ECWCS Gen III Level II top includes both moisture-wicking construction and anti-microbial, anti-odor treatment. Moisture is pulled away from the skin and transferred toward the outer layer. The anti-microbial treatment reduces odor buildup during extended wear, making the top practical for multi-day field use or backcountry trips without access to laundry.
What colors and sizes are available?
The Rothco ECWCS Gen III Level II top is available in Black (S–4XL), AR 670-1 Coyote Brown (XS–4XL), Olive Drab (S–3XL), and Desert Sand (S–2XL). Size availability varies by color, so check the variant selector for the specific combination needed. A size chart for the ECWCS Mid-Weight Top is available on Rothco's website.
Can the zip collar be worn as a turtleneck?
Yes. The Rothco ECWCS Gen III Level II top has a zip collar that can be opened for ventilation during high-output activity or zipped fully closed and worn as a turtleneck for additional neck coverage in wind or extreme cold. The thumb holes at the cuffs serve a similar purpose, keeping sleeves anchored in place rather than riding up inside an outer layer.

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.
