When the mercury dives and the wind bites, the Frostline Fleece Zip Jacket keeps little chargers locked in the warmth. Built for cold-day chaos — playground climbs, snow fort missions, or frosty trail runs — this midweight fleece packs all the heat without the bulk. Soft, rugged, and built for motion.
Key Features:
Thick Polar Fleece: Plush, dense texture traps heat for max insulation.
Durable Stitch Construction: Reinforced seams stand up to tumbles and snow dives.
Zip Chest Pocket: Quick stash for gloves, snacks, or trail treasures.
Full-Length Zipper: Easy on/off — even with mitts on.
Stand Collar: Blocks wind and seals warmth around the neck.
Soft Bound Cuffs & Hem: No ride-up, no chill creep.
Recommended Use:
Made for mountain towns, schoolyard scrambles, and every cold snap in between. Pull it under a shell for deep-winter layering or rock it solo on crisp mornings when breath fogs and adventure calls.
Bottom Line:
Small frame. Big send energy. The Frostline Fleece keeps stoke levels high when temps drop low.
