Heavyweight Antarctic Grid Fleece Bottom brings breathable warmth to winter layering
What Our Gearhead® Experts Are Saying:
"I’ve been layering the Antarctic Grid Fleece Bottom under my ski bibs on the coldest days, and it’s been a game changer. The grid fleece traps heat without making me overheat, and the stretch makes it super comfy on long tours or resort days."
When it’s bitter cold and we need reliable warmth without adding bulk, we reach for the Heavyweight Antarctic Grid Fleece Bottom. Designed with performance in mind, these technical baselayer pants combine warmth, breathability, and next-to-skin comfort to keep us moving confidently through winter’s worst.
The gridded fleece interior traps heat while allowing airflow to prevent clamminess, while a premium fabric blend—including merino wool, rayon, and recycled polyester—offers stretch, durability, and natural odor resistance. Built for long days on the skin track or chairlift, this heavyweight layer keeps us comfortable when staying warm is non-negotiable.
