Mountain Warehouse IsoCool Mid Layer Top - Black - Size 12

IsoCool fabric is designed to be quick-drying and highly breathable. It works by wicking moisture (perspiration) away from your skin to the outer surface of the fabric, where it can evaporate, helping to keep you cool and dry.

The Bend & Stretch Full-Zip Midlayer is designed for moderate conditions or as a layering piece. For very cold weather, it should be worn as part of a layering system, with a warm insulating layer underneath and a waterproof/windproof outer shell.

The midlayer should fit comfortably without being too tight or too loose. It should allow for full freedom of movement. Check the product's specific size chart if available, and consider if you prefer a snug fit for layering or a slightly looser fit.

Yes, its lightweight, stretchy, and breathable design makes it suitable for running and other high-intensity activities where moisture management and freedom of movement are important.

This product comes with a 2-year warranty against manufacturing defects.

While the fabric has some breathability, it is not waterproof. It is best suited as an insulating layer underneath a waterproof or water-resistant outer shell in wet conditions.

Ensure you are using the correct detergent and avoiding fabric softeners, which can clog the fabric's pores and reduce breathability. Follow care instructions precisely.

For minor issues, carefully trim any loose threads. For significant damage, contact customer support as the item may be covered under warranty.

Gently try to work the zipper back and forth. Applying a small amount of graphite (from a pencil tip) or a specialized zipper lubricant to the teeth can help. Ensure no fabric is caught in the zipper track.
