Technical Information

Fleece component: Insulation provided by air
The fleece component is designed to trap air thanks to the volume created by its texture, this air acts as a natural insulator, keeping the body warm. The brushing of the knit fabric is what traps the air.

Money well spent
Slightly small and not really what I was expecting
Used for 7 to 12 months
Initially, I expected these to replace a pair of well-worn Treksters, but the fabric was neither thick- or robust- enough. They were cut strangly too - as if they would be worn as hipsters, which is not very sensible for trekking gear as they either fall down, or at least expose your kidneys. So, I thought I'd try wearing them under a pair of thin trekking trousers which I love in the summer. Unfortunately, they were just too low cut hanging off one's hips.

It looks totally different in pics. Poor quality

This product is warm and serves the purpose.
But, I took it along for a trek, used just for a day during the sleep-time at night, and next day I found that the stitch near abdomen/groin is gone.
