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.\u003c\/p\u003e\n\n\u003ch2\u003eMoisture Management When It Counts\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eFit That Moves With You\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eAnti-Microbial Treatment for Extended Wear\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrid fleece construction:\u003c\/strong\u003e mid-weight, breathable fabric designed for cold-weather layering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e97% polyester \/ 3% spandex:\u003c\/strong\u003e stretch blend that moves with the body\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMoisture wicking:\u003c\/strong\u003e transfers sweat away from skin toward the outer layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-microbial and anti-odor treatment:\u003c\/strong\u003e reduces odor during extended wear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eZip collar:\u003c\/strong\u003e adjustable for ventilation or closed as a turtleneck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended back tail and thumb holes:\u003c\/strong\u003e maintain coverage and sleeve position during active movement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBrand\u003c\/td\u003e\n      \u003ctd\u003eRothco\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSystem\u003c\/td\u003e\n      \u003ctd\u003eECWCS Gen III, Level II (Mid-Weight)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003e97% Polyester \/ 3% Spandex grid fleece\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSleeve type\u003c\/td\u003e\n      \u003ctd\u003eLong sleeve\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eClosure\u003c\/td\u003e\n      \u003ctd\u003eZipper (zip collar)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMoisture wicking\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAnti-microbial\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eGender\u003c\/td\u003e\n      \u003ctd\u003eMen's (adult)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eColors available\u003c\/td\u003e\n      \u003ctd\u003eBlack, AR 670-1 Coyote Brown, Olive Drab, Desert Sand\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSizes available\u003c\/td\u003e\n      \u003ctd\u003eXS–4XL (range varies by color; see variant selector)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eGarment weight (S–XL)\u003c\/td\u003e\n      \u003ctd\u003e0.81 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eGarment weight (2XL)\u003c\/td\u003e\n      \u003ctd\u003e0.88 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eGarment weight (3XL–4XL)\u003c\/td\u003e\n      \u003ctd\u003e0.94 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOrigin\u003c\/td\u003e\n      \u003ctd\u003eChina\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe 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 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.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat does \"ECWCS Gen III Level II\" mean?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eECWCS 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.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the fabric, and how does it perform in the cold?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes the top have any odor or moisture management?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. 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.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat colors and sizes are available?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan the zip collar be worn as a turtleneck?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. 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.\u003c\/p\u003e","brand":"Rothco","offers":[{"title":"Black \/ S","offer_id":67126249292147,"sku":"RTC-69030-BK-S","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ M","offer_id":67126249324915,"sku":"RTC-69030-BK-M","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":67126249357683,"sku":"RTC-69030-BK-L","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ XL","offer_id":67126249390451,"sku":"RTC-69030-BK-XL","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 2XL","offer_id":67126249423219,"sku":"RTC-69031","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 3XL","offer_id":67126249455987,"sku":"RTC-69032","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 4XL","offer_id":67126249488755,"sku":"RTC-69033","price":61.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ XS","offer_id":67126249521523,"sku":"RTC-69040-XS","price":54.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ S","offer_id":67126249554291,"sku":"RTC-69040-CCB-S","price":54.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ M","offer_id":67126249587059,"sku":"RTC-69040-CCB-M","price":54.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ L","offer_id":67126249619827,"sku":"RTC-69040-CCB-L","price":54.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ XL","offer_id":67126249652595,"sku":"RTC-69040-CCB-XL","price":54.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ 2XL","offer_id":67126249685363,"sku":"RTC-69041","price":56.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ 3XL","offer_id":67126249718131,"sku":"RTC-69042","price":58.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ 4XL","offer_id":67126249750899,"sku":"RTC-69043","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ S","offer_id":67126249783667,"sku":"RTC-69060-SML","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ M","offer_id":67126249816435,"sku":"RTC-69060-MED","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ L","offer_id":67126249849203,"sku":"RTC-69060-LRG","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ XL","offer_id":67126249881971,"sku":"RTC-69060-XLRG","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ 2XL","offer_id":67126249914739,"sku":"RTC-69061","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ 3XL","offer_id":67126249947507,"sku":"RTC-69062","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ S","offer_id":67126249980275,"sku":"RTC-69020-DS-S","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ M","offer_id":67126250013043,"sku":"RTC-69020-DS-M","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ L","offer_id":67126250045811,"sku":"RTC-69020-DS-L","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ XL","offer_id":67126250078579,"sku":"RTC-69020-DS-XL","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ 2XL","offer_id":67126250111347,"sku":"RTC-69021","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/69030-RIGHT-C.webp?v=1792112714","url":"https:\/\/bulletproofzone.com\/products\/rothco-ecwcs-gen-iii-level-ii-mid-weight-base-layer-top","provider":"Bulletproof Zone","version":"1.0","type":"link"}
