The Columbia Men's Crystal Leaf Omni-Heat Helix Technical Half Zip Fleece is a performance midlayer built for active use on the trail and in winter sports conditions, combining Columbia's innovative Omni-Heat Helix insulation with sweat-wicking Omni-Wick technology to keep you warm, dry and moving comfortably. It's a versatile piece that works equally well as a standalone layer on milder days or as part of a wider layering system when the temperature drops — pair it with a softshell or hardshell from our men's hiking and outdoor clothing range for full weather protection.

• Omni-Heat Helix insulation — high-efficiency cells manage heat and airflow to retain warmth during activity without overheating
• Omni-Wick moisture management pulls sweat to the fabric surface to evaporate, keeping you dry and comfortable next to skin
• 4-way comfort stretch for unrestricted movement across a full range of motion
• Half-zip collar for quick and easy ventilation on the move
• Thumbholes on cuffs keep sleeves in place and extend hand coverage
• Stretch binding on cuffs and hem seals out cold air
• Locker loop for hanging when not in use
• Suited to hiking, trail use, and winter sports as an active insulating midlayer
