Hot Chillys, which delivers performance base layers and winter accessories, unveiled a lightweight base layer crafted from luxurious microfiber jersey knit fabric, duly named Silkys.

Featuring UPF 30+ and four-way stretch, this ultra-light garment combines comfort and performance with a touch of luxe.

“Body fit base layers were the start of Hot Chillys outdoor performance products and forty years later, we want to continue to stay true to that vision of innovation in the outdoor landscape” said Jackie Murrel, Hot Chillys’ head of design. “We took our original product, which revolutionized clothing at the time, and developed something new for today’s environment. The Silkys base layer brings a luxurious feeling in a lightweight form.”

Hot Chillys’ offers a performance fit base layer to take high tech fabrics – previously found in performance runningwear – and winterize them to provide thermal protection against the elements. Hot Chillys utilizes cutting edge technology to keep people dry and warm in every activity. The launch of Silkys provides a new level of comfort and softness to a classic collection of base layers. Silkys are great for an extra travel layer, cozying up by the fireplace, coffee on the porch on a brisk morning or a weekend camping trip. Equipped with MTF technology, this fabric ensures superior performance for cool conditions while keeping the body dry and comfortable.
