Polartec® Windbloc®

Polartec® Windbloc® fabrics block 100% of the wind and offer maximum protection from the cold and the elements. A soft hand, stretch and a durable water repellent finish (DWR) ensure the highest levels of quality and comfort.

Polartec® Windbloc® fabrics combine the warmth of Polartec® thermal fabrics with a polyurethane barrier membrane that allows moisture vapor transmission and is completely windproof and waterproof, eliminating the need for a windbreaker or additional shell. This reduces the weight and number of layers needed to protect and insulate.

These fabrics are very durable and quiet and have enhanced stretch and recovery, making them appropriate for general outerwear and accessories where weather protection is desirable. Polartec® Windbloc® fabrics are ideal when the activity level is low or intermittent and when cold and inclement weather demands high-performance outer protection.

Technical Highlights:
1) Blocks 100% of the wind to prevent wind chill
2) Provides warmth without the weight and bulk of traditional insulating fabrics
3) Water repellent surface sheds rain and snow
4) Non-restrictive fit for full range of motion
5) Creates less noise than a traditional shell
6) Polyurethane film membrane allows internal moisture to move to outer surface, leaving you dry and comfortable in all but the most active sports
7) Durable. Will outlast traditional fabrics
8) Machine washable

M1

Marmot M-series fabrics are designed for moving light and fast. They combine stretchable, water repellent, abrasion resistant and highly breathable shell materials with insulating buffer materials on the inside.

M1 shells provide the highest level of warmth and thermal protection. They are best for intermittent aerobic use in cold conditions.
