Whether you’re catching first tracks on a freezing morning in the **Wentworth Valley**, snowshoeing through a quiet, snow-covered **Kejimkujik National Park**, or layering up for a damp, windy winter walk along the Atlantic coast, the Smartwool Women’s Classic Thermal Merino Base Layer Bottom is your ultimate defense against the elements. Formerly known as the legendary Merino 250, this heavyweight thermal pant delivers maximum, reliable insulation without ever feeling bulky or restrictive under your gear.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  Crafted from 100% premium, ZQ-certified Merino wool using a dense interlock knit, this base layer sits incredibly soft next to your skin while working hard to regulate your body temperature. The natural properties of Merino wool mean it breathes exceptionally well, pulls moisture away from your body during high-output activities, and remains completely odor-resistant over multi-day trips. Designed with a slim, contoured fit that layers beautifully under shells or snow pants, it features a comfortable mid-rise waist with a Merino-lined elastic band and smooth flatlock seams to ensure a completely chafe-free experience all day long.\n\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003e100% Premium Merino Wool:\u003c\/b\u003e Pure, responsibly sourced Merino next to your skin delivers high-tier warmth, breathability, and natural odor control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eHeavyweight 250 g\/m² Insulation:\u003c\/b\u003e Smartwool’s warmest pure-wool fabric construction, optimized for elite performance in sub-zero winter climates.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eInterlock Knit Construction:\u003c\/b\u003e Enhances overall garment durability and stretch recovery while providing a super-soft, plush feel against the skin.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eContoured Slim Fit:\u003c\/b\u003e Follows the body's natural contours to create an efficient thermal boundary layer that fits perfectly under outer shells without bunching.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eMerino-Lined Mid-Rise Waistband:\u003c\/b\u003e Features a wide, comfortable elastic waistband lined entirely with Merino wool to eliminate pressure points and moisture buildup.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eChafe-Free Flatlock Seams:\u003c\/b\u003e Flat-stitched seams completely remove friction and irritation, making it comfortable for all-day continuous movement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eBest For\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Effort:\u003c\/b\u003e Downhill skiing, snowboarding, winter trail running, snowshoeing, and cold-weather backcountry camping.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Goal:\u003c\/b\u003e Eliminating the bite of deep winter freezes and managing sweat during stop-and-go mountain activities.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eThe Conditions:\u003c\/b\u003e Sub-zero environments and damp, freezing winter climates where reliable core insulation is non-negotiable.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eMaterial Composition:\u003c\/b\u003e 100% Merino Wool (Exclusive of decoration)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eFabric Weight:\u003c\/b\u003e 250 g\/m² (Heavyweight Thermal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eInseam (Size M):\u003c\/b\u003e 30.5 in. \/ 77.5 cm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eRise \u0026amp; Fit:\u003c\/b\u003e Mid-Rise \/ Slim Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eStyle Code:\u003c\/b\u003e SW019242\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCare Instructions:\u003c\/b\u003e Machine wash warm gentle cycle inside out, tumble dry low (do not iron decorations, bleach, or dry clean)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Smartwool","offers":[{"title":"Charcoal Heather \/ Med","offer_id":45419326505017,"sku":"210000010800","price":99.0,"currency_code":"CAD","in_stock":true},{"title":"Charcoal Heather \/ Lg","offer_id":45419326537785,"sku":"210000010801","price":99.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/3251\/2825\/files\/txpljwlrkddkipxs6tj9.png?v=1769773658","url":"https:\/\/3mile.ca\/products\/smartwool-classic-thermal-merino-base-layer-bottom-womens","provider":"3 Mile Outfitters","version":"1.0","type":"link"}
