zWeld Seams

The patented Mountain Hardwear zWeld technology is currently the most advanced welding technique in the outdoor industry.

• Eliminates need for taping seams, which reduces materials and weight
• Narrow 6mm seams increase breathability
• Fully waterproof
• Seam Z strength is as strong as sewn construction (What is Z Strength? The amount of force a seam can withstand when pulled along the Z axis. The higher the Z strength, the more durable the garment.)
• First welded seam to work with stretchy fabrics: zWeld seams stretch with the wearer while maintaining strength and waterproofness
