The Hypertherm Race Smock is an incredibly versatile piece of reversible insulation. Highly packable, it offers windproof protection and warmth that is light enough to be worn whilst on the move. Turning the jacket inside out allows more airflow into the insulation keeping your cooler during high exertion.
The Men's VapourLight Hypertherm Race Smockis an adaption of the popular Hypertherm Jacket which was extensively tested on the demanding 1,2ookm great Himalayan Trail. Combining ultra-lightweight warmth with a reversible twist, wear it one way round for wind proofing and the other for better cooling and breathability.
The VapourLight Hypertherm Smock is a stripped-down, 156g (size large) pull-on design, with minimal frills using 40g Berghaus HydroLoft Elite, the ultimate in breathable synthetic insulation. If you seek the world's lightest synthetic mid-layer look no further.
Berghaus' VapourLight Hypertherm Smock is a versatile insulation layer. The wamrth that you'll get from this jacket can be slightly varied by which way round you were it. It's reverisble so the side with dual colours offers the most warmth due to that fabric being more wind resistant, whereas the mono coloured side breathes more and is therefore cooler.
Usually the difference in this type of garment between the two sides is about 10% more warmth. If this aspect interests you then great but it's not the be all and end all of the jacket, it's still a high quality lightweight insulating piece of kit. It packs down to almost nothing into the included stuff sack, ideal for when you need it most but you won't notice the extra weight in your pack.
