Preshrunk construction means the fit holds after washing.

The 100% cotton construction is soft against skin, making these bottoms comfortable for all-day wear whether used as a standalone layer or beneath outer pants.\u003c\/p\u003e\n\n\u003ch2\u003ePreshrunk for a Consistent Fit\u003c\/h2\u003e\n\u003cp\u003eThe cotton is preshrunk before cutting and sewing, so the size you order is the size you wear, including after repeated laundering. Cuffed ankles keep the hem in place at the leg opening, preventing the bottoms from riding up under outer layers during movement.\u003c\/p\u003e\n\n\u003ch2\u003eBase Layer Versatility\u003c\/h2\u003e\n\u003cp\u003eThese bottoms work as a standalone cold-weather layer or as the foundation of a full thermal system.

The preshrunk construction and cuffed ankles make them a practical choice for buyers who layer frequently and need consistent sizing over time.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese are not insulated or waterproof bottoms and are not designed for wet conditions. They are a base layer only, not outerwear. Buyers who need moisture-wicking synthetic performance fabric should look at non-cotton alternatives, as cotton retains moisture when wet.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWill these bottoms shrink after washing?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Indera Extra Heavyweight Thermal Knit Bottoms are made from 100% preshrunk cotton, so the fabric has already been treated to minimize shrinkage. The size ordered should remain consistent through repeated machine washing, making fit predictable over the life of the garment.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow heavy is the fabric compared to standard thermal underwear?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThese bottoms use a 9 oz knit, which is classified as extra heavyweight. At that weight, the Indera bottoms provide noticeably greater fabric density and heat retention than lighter thermals, making them suited to colder conditions where a lighter thermal would be insufficient.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan these be worn as an outer layer or only under pants?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Indera thermal knit bottoms are designed primarily as a base layer worn beneath outer pants. The cuffed ankles and fitted knit construction are optimized for layering. They can be worn alone in low-activity indoor settings, but they are not styled or finished as standalone outerwear.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs a matching thermal top available?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. A matching Indera thermal top is available separately, allowing buyers to assemble a coordinated full-body base-layer set from the same fabric weight and construction. The two pieces are sold individually rather than as a bundled kit.\u003c\/p\u003e","brand":"Indera","offers":[{"title":"S","offer_id":67128813519219,"sku":"RTC-6458-S","price":28.99,"currency_code":"USD","in_stock":true},{"title":"M","offer_id":67128813551987,"sku":"RTC-6458-M","price":28.99,"currency_code":"USD","in_stock":true},{"title":"L","offer_id":67128813584755,"sku":"RTC-6458-L","price":28.99,"currency_code":"USD","in_stock":true},{"title":"XL","offer_id":67128813617523,"sku":"RTC-6458-XL","price":28.99,"currency_code":"USD","in_stock":true},{"title":"2XL","offer_id":67128813650291,"sku":"RTC-6459","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/6458-LEFT-C.webp?v=1792122606","url":"https:\/\/bulletproofzone.com\/products\/indera-extra-heavyweight-thermal-knit-bottoms","provider":"Bulletproof Zone","version":"1.0","type":"link"}
