{"product_id":"rothco-ecwcs-gen-iii-level-ii-mid-weight-base-layer-bottoms","title":"Rothco ECWCS Gen III Level II Mid-Weight Base Layer Bottoms","description":"\u003cp class=\"product-lead\"\u003eThe Rothco ECWCS Gen III Level II Mid-Weight Underwear Bottoms are cold-weather base layer pants built from a 93% polyester \/ 7% spandex grid fleece fabric, designed for military personnel, tactical professionals, and outdoor users who need moisture management and insulation in a layering system. The bottoms are part of the Extended Cold Weather Clothing System (ECWCS) and are available in Black, AR 670-1 Coyote Brown, Olive Drab, and Desert Sand, in sizes XS through 3XL depending on color.\u003c\/p\u003e\n\n\u003ch2\u003eMoisture Management Under Load\u003c\/h2\u003e\n\u003cp\u003eThe grid fleece construction wicks sweat and moisture away from the skin and transfers it outward to the next layer, where it can evaporate quickly. For anyone wearing multiple layers through sustained physical activity (a patrol, a long hike, a ski approach), the base layer stays dry against the skin rather than becoming a cold, wet layer. The pull-on waist and elastic leg bottoms help seal in body heat at the waist and ankle, reducing cold-air intrusion during movement.\u003c\/p\u003e\n\n\u003ch2\u003eStretch and Fit for Active Use\u003c\/h2\u003e\n\u003cp\u003eThe polyester-spandex blend allows the grid fleece to flex and move with the body rather than binding at the knees or hips. The bottoms include an access fly for convenience during extended wear. An elastic waist removes the need for a belt at the base layer, keeping the fit close and reducing bulk under outer layers. Rothco's size reference places a Medium on a 6'1\" frame with a 32\" waist, which can help calibrate fit across the size run.\u003c\/p\u003e\n\n\u003ch2\u003eAntimicrobial Treatment for Extended Missions\u003c\/h2\u003e\n\u003cp\u003eThe fabric carries an antimicrobial and anti-odor treatment, which matters when laundry access is limited. Multi-day field operations, backcountry trips, and extended deployments where the same base layer may be worn for consecutive days are exactly the conditions this treatment addresses.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMid-weight grid fleece:\u003c\/strong\u003e 93% polyester \/ 7% spandex construction designed for cold-weather layering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMoisture wicking:\u003c\/strong\u003e transfers sweat away from skin to the outer layer for faster drying\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAntimicrobial and anti-odor:\u003c\/strong\u003e fabric treatment for freshness during extended wear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccess fly:\u003c\/strong\u003e included for convenience during prolonged use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElastic waist and leg bottoms:\u003c\/strong\u003e help retain body heat and keep the fit close under outer layers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eECWCS Gen III Level II:\u003c\/strong\u003e part of the Extended Cold Weather Clothing System layering standard\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\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003e93% Polyester \/ 7% Spandex\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFabric type\u003c\/td\u003e\n      \u003ctd\u003eMid-weight grid fleece\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eECWCS layer\u003c\/td\u003e\n      \u003ctd\u003eGen III Level II (mid-weight)\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\u003eAntimicrobial\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eClosure\u003c\/td\u003e\n      \u003ctd\u003ePull-on with elastic waist; access fly\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eGender\u003c\/td\u003e\n      \u003ctd\u003eMen's\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAvailable colors\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\u003eAvailable sizes\u003c\/td\u003e\n      \u003ctd\u003eXS–3XL (size range varies by color)\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\"\u003eThese bottoms suit military personnel, law enforcement, and outdoor users who need a mid-weight thermal base layer that manages moisture and controls odor during cold-weather operations, field exercises, hunting, skiing, snowboarding, hiking, or camping.

They are not a standalone cold-weather garment and are intended to be worn under additional insulating and shell layers.

Gen III Level II is the mid-weight layer, worn over a lightweight moisture-wicking base (Level I) and under insulating and shell layers, intended for moderately cold to cold conditions where active movement is expected.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow does the moisture-wicking work in a layered system?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rothco ECWCS Gen III Level II Bottoms pull sweat away from the skin and push it outward toward the next layer, where it can evaporate. This keeps the base layer from becoming wet and cold against the skin during sustained activity, which is the primary cause of chill in cold-weather layering systems.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat sizes are available, and how should I size these bottoms?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ECWCS Gen III Level II Bottoms are available in XS through 3XL, though the full size range varies by color. Rothco's fit reference places a Medium on a 6'1\" frame with a 32\" waist and 32\" inseam. A size chart specific to the ECWCS Mid-Weight Bottom is available from Rothco's website for a more detailed fit guide.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan these be worn for non-military outdoor activities?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The Rothco ECWCS Gen III Level II Bottoms are suited for any cold-weather activity where a moisture-wicking mid-weight base layer is useful, including hiking, camping, skiing, snowboarding, and hunting. The ECWCS designation reflects the layering standard they are built to, not a restriction on use.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs there a matching top available?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eRothco makes a matching ECWCS Gen III Level II Underwear Top built from the same 93% polyester \/ 7% spandex mid-weight grid fleece. Wearing the top and bottoms together completes the Level II layer of the ECWCS Gen III system.\u003c\/p\u003e","brand":"Rothco","offers":[{"title":"Black \/ S","offer_id":67126360244595,"sku":"RTC-69034-BK-S","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ M","offer_id":67126360277363,"sku":"RTC-69034-BK-M","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":67126360310131,"sku":"RTC-69034-BK-L","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ XL","offer_id":67126360342899,"sku":"RTC-69034-BK-XL","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 2XL","offer_id":67126360375667,"sku":"RTC-69035","price":50.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ XS","offer_id":67126360408435,"sku":"RTC-69044-XS","price":47.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ S","offer_id":67126360441203,"sku":"RTC-69044-CB-S","price":47.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ M","offer_id":67126360473971,"sku":"RTC-69044-CB-M","price":47.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ L","offer_id":67126360506739,"sku":"RTC-69044-CB-L","price":47.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ XL","offer_id":67126360539507,"sku":"RTC-69044-CB-XL","price":47.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ 2XL","offer_id":67126360572275,"sku":"RTC-69045","price":50.99,"currency_code":"USD","in_stock":true},{"title":"AR 670-1 Coyote Brown \/ 3XL","offer_id":67126360605043,"sku":"RTC-69046","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ S","offer_id":67126360637811,"sku":"RTC-69064-SML","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ M","offer_id":67126360670579,"sku":"RTC-69064-MED","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ L","offer_id":67126360703347,"sku":"RTC-69064-LRG","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ XL","offer_id":67126360736115,"sku":"RTC-69064-XLRG","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Olive Drab \/ 2XL","offer_id":67126360768883,"sku":"RTC-69065","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ S","offer_id":67126360801651,"sku":"RTC-69024-DS-S","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ M","offer_id":67126360834419,"sku":"RTC-69024-DS-M","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ L","offer_id":67126360867187,"sku":"RTC-69024-DS-L","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ XL","offer_id":67126360899955,"sku":"RTC-69024-DS-XL","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Desert Sand \/ 2XL","offer_id":67126360932723,"sku":"RTC-69025","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/69034-FRONT-A1.webp?v=1792114784","url":"https:\/\/bulletproofzone.com\/products\/rothco-ecwcs-gen-iii-level-ii-mid-weight-base-layer-bottoms","provider":"Bulletproof Zone","version":"1.0","type":"link"}
