Product Reviews 
Discover Damart’s range of thermal jumpers – warm, slim-fit knitwear made to be worn all winter long. From classic crew necks to snug polo necks, our women’s and men’s thermal jumpers are made with Damart’s exclusive Thermolactyl fibre, so you stay warm without the weight of a traditional heavy knit.
Shop our full range of ladies’ and men’s thermal jumpers in sizes 10–28, featuring Thermolactyl fabric in three warmth grades – so you can choose exactly how much warmth you need. Whether you prefer a lightweight layer for autumn or a extreme warmth for the coldest winter days, our thermal knitwear works hard without adding bulk.
Thermal jumpers are the perfect outer layer for autumn and winter. Wear one over a thermal vest or fitted long-sleeve top for extra warmth, or style on its own on milder days. The slim Thermolactyl knit sits neatly beneath a coat or jacket without adding bulk – making it ideal for layering up on the coldest days.
A thermal polo neck jumper is perfect for those biting cold mornings. Wear one under a blazer for a smart layered look, or style with wide-leg trousers and boots for a polished winter outfit. The polo neck adds an extra layer of warmth around the neck – a key area for heat loss.
Men’s thermal jumpers work equally hard. Wear one over a thermal base layer for outdoor activities, or on its own as a warm everyday style. Our men’s styles sit neatly beneath a coat or jacket without any added bulk – easy to dress up or down.
A thermal jumper is a knitted top made from thermally insulating fabric – designed to trap warmth close to the body. Damart’s thermal jumpers use Thermolactyl fibre, which is ultra-lightweight yet exceptionally warm, making them a brilliant everyday layer that won’t feel heavy or bulky.
Yes – a good thermal jumper can make a significant difference to how warm you feel in cold weather without the bulk of a thick jumper. Damart’s Thermolactyl range is slim-fit and lightweight, so you can wear it under your usual clothes without anyone knowing it’s there.
A thermal vest is a sleeveless base layer worn close to the skin, while a thermal jumper is a knitted outer layer you wear on top. For maximum warmth on really cold days, wear both together – a thermal vest underneath with a thermal jumper over the top.
Most of Damart’s thermal jumpers are machine washable – always check the care label for specific instructions. Thermolactyl fabric is designed to be easy-care and retain its shape and warmth after repeated washing, making it a practical choice for everyday wear.
