Meet Therm-ic Fusion Uni, a unisex heated ski sock set crafted to keep feet comfortable as winter brings its chill. The soft, breathable knit blends with a micro-channel structure to help wick moisture, creating a welcoming microclimate inside the boot. They’re designed to support long days on the slopes or snowy excursions, with a careful balance of warmth, fit, and durability that feels natural against the skin.
Heat Fusion technology provides even warmth across the toes, instep, and forefoot. Reinforced heel and toe zones add durability for all-day wear, while a snug fit in the shin and calf area helps prevent bunching. A longer design keeps the battery pack out of your boot, reducing bulk and maintaining freedom of movement.
The sock contains a soft merino wool blend, with 15% merino wool contributing to warmth and a degree of natural moisture management. This combination aims to offer comfort during variable winter activities without sacrificing breathability.
The included S-Pack 700 batteries attach quickly via snaps and feed power to the entire foot through hidden heating elements. With three heat levels, you can tailor the warmth to the conditions, from brisk chairlift mornings to longer days on colder slopes. A USB charging cable is included for convenient recharging, though a USB mains charger is not included with the set.
Usage notes and everyday readiness
This set blends warmth, soft touch, and moisture management with practical, real-world use in mind. The design emphasizes comfort and ease of use, offering a flexible warmth option that can adapt to changing outdoor conditions without promising specific outcomes. It aims to support your winter activities with a reliable, user-focused approach to staying warm.
Q: How long does the heat last with the included batteries?
A: Up to 7 hours of warmth on a single charge with the S-Pack 700, depending on the heat level.
Q: Can I control heat levels while skiing?
A: Yes, heat levels can be adjusted via the battery pack; some setups offer smartphone control for convenience.
