Clothing

These are the different types of layers and how to were them. I found all this info at the MEC website.
Base layer

Base layers (also known as underwear) should transport moisture away from the skin and disperse it to the air or outer layers where it can evaporate.
The best base layer materials are synthetics (polypropylene and polyester).
These are light and strong, absorb very little water, and are quick to dry.
Seamless or flat-seam garments lie flat and won't press into your skin under a harness or pack.
Base layers should fit snugly without being constricting.


Mid layers

The mid-layer provides insulation and continues the transportation of moisture from the inner layer.
Wool and synthetics are well suited to this because the structure of the fibres creates small air spaces that trap molecules of warm air.
As with the inner layer, this layer should be snug but not constricting.

outer layers

The outer layer protects you from the elements and should allow air to circulate and excess moisture to escape.
A shell made of a breathable and waterproof fabric, such as Gore-Tex, will protect you from wind and rain, and allow water vapour to escape.


gloves


In frigid temperatures, a layered mitt system is the best choice for warmth.
Layers dry faster than one heavily insulated piece, and let you swap out wet layers.
Wearing a shell outer glove and a thin polypro or Windstopper® liner is a good compromise

Features

• Cuffs keep out snow and insulate the wrist – an area of high heat loss. Look for cuffs that fit snugly but don’t impede circulation. They should be long enough to keep you covered when you reach way out for a pole-plant or way up for a tool placement.
• Reinforced palms are durable and offer good grippy texture. Double-stitching and extra layers of fabric will protect high-wear areas like the thumb, lower palm, and forefingers.
• Padding on the backs of the hands and fingers protects you when your errant ice tool swing catches “nothing but knuckle.”
• That little loop on the back of the forefinger lets you hang the gloves upside down on your harness so they don’t fill with snow while you climb
