Warmth without the wool. The JACKPINE® Two Four Sevens are engineered for cold UK winter days, frosty morning dog walks, and cosy evenings by the fire.
Crafted from 100% PETA-approved synthetic microfibres, they deliver thermal heat retention, a plush cushioned sole, and moisture-wicking breathability with zero animal cruelty.
Many traditional winter and thermal socks rely heavily on sheep’s wool. While wool is insulating, it carries serious ethical drawbacks, can feel itchy or scratchy against bare skin, and stays damp when wet. JACKPINE Two Four Sevens prove that modern vegan materials provide a far better winter experience.
Engineered with high-density synthetic thermal microfibres, our winter socks trap radiant body heat within tiny insulating air chambers while actively wicking away sweat. The result? Toasty warm, dry feet whether you’re stomping through winter mud in wellies, hiking chilly hills, or lounging at home. Plus, with our Buy One, Donate One promise, your winter sock purchase donates a pair of warm socks to UK homeless shelters during the coldest months of the year.
Yes. Our Two Four Sevens series uses high-gauge thermal knit microfibres engineered to deliver equivalent thermal resistance to wool without the bulk or scratchiness. Unlike wool, which retains water and loses insulating power when damp, synthetic yarns dry rapidly and keep insulating.
Definitely. The reinforced heel and cushioned underfoot beds are designed specifically to buffer friction from stiff winter walking boots, work boots, and rubber wellingtons, helping avoid heel blisters and cold spots.
Yes. Unlike delicate wool socks that shrink or felt, JACKPINE vegan socks can be machine washed at 30°C. They maintain their plush softness, elastic shape, and cushioning year after year.
No. JACKPINE is certified 100% PETA-approved vegan. We never use merino wool, cashmere, silk, or animal-based dyes and softeners.
