Super Warm Heavyweight Icebreaker® Original™ 320 GSM Half Zip Mid-Layer

Men's Icebreaker 320GSM Half Zip. This is "THE" thermal wool layering piece from the Icebreaker® collection. The 320GSM weight merino wool can be worn as a Layer 1 next to skin or as a Layer 2 second layering piece over a base and is perfect for the extreme cold and looks superb into the bargain.

This is thermal regulation at it's very best. The Warmest and heaviest fabric offering from the Icebreaker® 100% Merino collection in a Slim Regular Fitted structure. The outdoor collection offers the best Warmth to Weight ratio of all the Icebreaker® ranges. Ideal next to skin or as a second Layer 2 over that first lightweight Layer 1 garment.

This long sleeve Half Zip with upstand mini-mock neckline and top quality lock down zipper with a mid chest finish when drawn down, is soft enough to be next to your skin while still keeping you warm, but not too warm so you maintain that "optimum" temperature in extreme conditions providing real natural performance from wool. Manufactured to exacting standards set and controlled by Icebreaker® themselves ensures the brand maintains high Ethical Production standards. Fibre is pre-shrunk at production stage so you don't lose shape and size during wear or after washing. Cuff thumb holes for added hand warmth when needed.

Thoughtfully designed with minimal strategically placed ultra-soft sewn seams with exceptional integrity, to avoid chafing and any risk of seam abrasion. Low impact brand decal to chest and 100% ethical Merino Wool content provides that Natural Anti-Bacterial Odour Control to ensure you stay fresh while you're trekking, travelling or traversing. The Original™ 320 Long Sleeve Half Zip is an all-natural, odour-resistant and highly insulating Merino Wool layering garment of exceptional quality that can also be machine washed easily at 40°.
