The Best Merino Wool Base Layer on the Market ... The Helly Hansen® Warm Freeze

The Helly Hansen Warm Freeze Half Zip features two different components, the inner Lifa® fibres ensure you stay dry, while the outer, soft Merino wool adds warmth and comfort. The Lifa® fabric used in HH Warm baselayers feature a hollow T3 fiber construction. Imitating polar bear fur, this innovative design provides even greater moisture transport and insulating performance.

This unique combination of man-made and natural fibre integration, delivers exceptional warmth and dryness in the coldest environments, as the T3™ Polypropylene content ensures moisture is rapidly moved away from the skin.

Merino Wool

In contrast to synthetics, Merino Wool can absorb up to 3 times its own weight in moisture vapour which means less sweat on your body. Merino absorbs the odours from sweat; you can wear merino wool for several days without the need for washing.  Less washing is good for the environment and good for garment integrity and good for your pocket too.

Editor's Note: A Layer for All Seasons

This is a very versatile layer, whether used on its own or combined with a non-thermal base-layer (e.g. Odlo Evolution or HH Revolution) for very cold conditions.

Summers in the UK can get surprisingly cold in the very early mornings and late evenings (i.e. when the sun isn't shining) and the Warm Freeze is a great replacement for a lighweight fleece (or light mid-layer) - it's likely lighter, packs down smaller, dries faster and importantly, you don't overheat when active. Just pack it away when the sun finally comes out to play.

It's instructive to read the reviews on the Helly Hansen site. They're actually very typical of reviews around the web.

Super Versatile - "Were this less durable, I would've worn it out ten times over. As it is, the top keeps on kicking despite the fact that I've been using it for about four years, and using it A LOT. I layer with this top in the spring, fall and winter when i'm out running, skiing or doing anything active. It has a great weight that keeps me warm but allows for freedom of movement in dynamic activity, and best of all (being wool): it doesn't stink! A great layering piece for lots of activities."

Sizing / Measuring

Helly Hansen are always a little on the small side. Here's their sizing for Large: chest: 41.5" - 43.5"

I'd say:

Medium: chest: 38" - 40.5"
Large: chest: 40.5" - 43"

So basically, HH are an inch out in our opinion.
