This is a beautifully made heavy weight base layer for comfort & temperature management in cold conditions. The Phase SV is made from two different weights of Phasic fabrics to give fantastic moisture management, odour control & supreme comfort next to the skin. This is a very versatile garment, serving as a fantastic winter base layer or it can be used as a light mid-layer when active in cooler conditions. Phasic fabric is made with a bi-component yarn that retains less moisture & dries faster to ensure your comfort & temperature regulation during stop & go activities. When things get sweaty the moisture wicking Phi yarns transports moisture away from your skin & disperses it across the whole garment; whilst the hydrophobic yarns remain dry & limit the garments ability to hold moisture. When you stop the garment dries incredibly quickly keeping you warmer & more comfortable. Phasic SV fabric makes up the main body whilst a lighter Phasic AR fabric makes up the underarm area to maximise breathability & comfort. Encapsulated silver ions in the fabric help to reduce bacteria build up & nasty pongs, so you can wear this top for extended periods before offending your mates. The soft stretchy fabric makes rolling up the sleeves easy when you really need to cool off.
