The Montane's 2017 Sonic T-Shirt has a silky feel and is extremely comfortable to wear in more extreme conditions. The design is tailored to sit close to the skin but it actually feels more free flowing and has highly breathable mesh material under the arms.

It suits hotter conditions, whether that is the weather or from higher intensity activity with a fabric that wicks away moisture, dries fast and provides protection from the sun at UPF 50+. Used as a baselayer the Sonic is not designed to provide warmth or insulation so even though it would be effective as part of a layered clothing system it is far more suited to the heat.

24/7 baselayer

It is a real pleasure to wear this t-shirt at all times. The fabric is very soft and comfortable. Stays cool and dry on hot and sweaty occasions, and reduces the heat felt. Retains no water at all, so that I can put it on just out of the washing machine. The cut is not too loose or too tight. Superb.
