All the same warmth and durability as the original Heat Holders® Worxx Crew sock, but in an Extra Large size.

Keep feet warm on the coldest of days and pull on this pair of solid color, extra large, crew length, reinforced Heat Holders® for men, the warmest thermal sock.

Thick, chunky and with a massive tog rating of 2.34, Heat Holders® are made from a specially developed heavy bulk yarn which has extreme thermal qualities. With long pile cushioning, these thermal socks will help keep feet fully comfortable and supported.
