Warm Base Layer

Andrew, 14/09/16

These pants have good warmth and are a comfortable material. They are not an ideal fit with proportionally wide waist and thin legs at the bottom.

Falling short.

Kaitlyn, 14/09/16

I wear this as leggings most days as they keep me warm but also give room for movement when I cycle or walk around at work. I really like the cut but the waist could sit a little higher on the hips as when you bend over it tends to slide down a little too low.

Warm, and great value for money

Michael, 05/07/17

An inexpensive, comfortable baselayer that is still going strong after 2 years. Provides a warm, cosy layer close to your body, but does restrict upper leg movement a little. Just note it doesn't breathe as well as a merino baselayer.
Uses: Downhill skiiing, hiking
Things I like:
Fit: True to size, and good length for the legs.
Comfort: The leg cuffs, about 5cm long, are comfortable all day long since the elastic is spread over a large area. The interior material is also super comfy against the skin, and I have never been itchy wearing these pants.
Warmth: Whilst not an especially thick layer, it is on the warmer side for base layers, probably because it doesn't breathe as well as others such as merino. As such, I have found it works best for sleeping, low-moderate intensity activities, or intense activity in less than 5C.
Things I didn't like:
Outer durability: I noticed a bit of pilling on the outside after only a few wears, mainly in areas of high wear/rubbing, but this hasn't affected how the fabric feels.
Freedom of movement: Slightly restricted range of motion, for instance in the lunge position, so it could be cut a little better for active use, such as around the crotch.

Good

Susan, 14/09/16

Great warmth and soft against the skin, although the fit is not really ideal. If they weren't unisex and were tailored for men and women separately then I would be giving a 5 star.
