{"product_id":"thermo-sweat-vest-compression-shirt","title":"Thermo Sweat Vest - Compression Workout Shirt for Men \u0026 Women","description":"\u003cp\u003e\u003cstrong\u003eBest for:\u003c\/strong\u003e Firm compression around your core at the lowest price in the sauna range. Men's and women's sizes.\u003c\/p\u003e\n\u003cp\u003eGRYNDWEAR's thermo sweat vest is a compression shirt that uses an inner heat-producing polymer fabric to raise the temperature around your midsection as you move, increasing sweat output through a session. Worn over the core, this thermo vest also provides firm compression that supports the torso and gives a smoother line under training kit.\u003c\/p\u003e\u003cp\u003eThe fabric is four-way stretch so the compression stays even as you move rather than rolling at the hem, and the inner face is smooth against the skin. The cut covers the abdomen and lower back, which is useful if you like a bit of warmth across the lower back during squats, deadlifts and conditioning work. The outer surface wipes clean and dries quickly between sessions.\u003c\/p\u003e\u003cp\u003eIt comes in a range of sizes for men and women — including a sweat vest for women fit — and the fit is intentionally tight, so measure at the waist and use the chart above. Understand what it does and does not do: it increases sweating, it does not burn fat or reduce fat in a specific area. Hydrate thoroughly, avoid wearing it in very hot conditions, and remove it if you feel light-headed. Check with a doctor first if you are pregnant or have blood pressure or heat-regulation concerns. Worn under a training top it is discreet enough that most people will not notice you have it on at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMaterial: inner heat-producing polymer with four-way stretch\u003c\/li\u003e\n\u003cli\u003eFit: firm compression across the abdomen and lower back\u003c\/li\u003e\n\u003cli\u003eUse: gym, cardio and conditioning sessions\u003c\/li\u003e\n\u003cli\u003eSizing: unisex range - measure your waist and see the chart above\u003c\/li\u003e\n\u003cli\u003eCare: hand wash cold, hang dry, do not tumble dry\u003c\/li\u003e\n\u003cli\u003eNote: increases sweat output; does not reduce body fat on its own\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAlso in the lineup:\u003c\/strong\u003e \u003ca href=\"\/products\/sauna-sweat-vest-men-zipper\"\u003eZip Sauna Vest\u003c\/a\u003e for a zip front; \u003ca href=\"\/products\/sauna-sweat-vest-men\"\u003eSauna Tank Top\u003c\/a\u003e to layer under a shirt; \u003ca href=\"\/products\/womens-neoprene-sauna-top-vest\"\u003eWomen's Sauna Top\u003c\/a\u003e cut for women; \u003ca href=\"\/products\/neoprene-sauna-vest-men-double-zipper\"\u003eNeoprene Sauna Vest\u003c\/a\u003e for neoprene with a double zip; \u003ca href=\"\/products\/sauna-sweat-jacket-hoodie\"\u003eSauna Hoodie\u003c\/a\u003e with a hood, for boxing; \u003ca href=\"\/products\/sauna-suit-sweat-top-and-pants\"\u003eTwo-Piece Sauna Suit\u003c\/a\u003e for full-body coverage.\u003c\/p\u003e","brand":"GRYNDWEAR","offers":[{"title":"Men \/ 2XL-3XL","offer_id":47224833966182,"sku":null,"price":27.99,"currency_code":"USD","in_stock":true},{"title":"Women \/ S-M","offer_id":47224833998950,"sku":null,"price":27.99,"currency_code":"USD","in_stock":true},{"title":"Women \/ L-XL","offer_id":47224834031718,"sku":null,"price":27.99,"currency_code":"USD","in_stock":true},{"title":"Women \/ 2XL-3XL","offer_id":47224834064486,"sku":null,"price":27.99,"currency_code":"USD","in_stock":true},{"title":"Men \/ S-M","offer_id":47224834097254,"sku":null,"price":27.99,"currency_code":"USD","in_stock":true},{"title":"Men \/ L-XL","offer_id":47224834130022,"sku":null,"price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/5663\/0118\/files\/hf_20261012_161723_f83db9cb-0118-4878-80bc-efb92cacddab.png?v=1791832049","url":"https:\/\/www.gryndwears.com\/products\/thermo-sweat-vest-compression-shirt","provider":"GRYNDWEAR","version":"1.0","type":"link"}
