What is the Sonic Ultra Zip?
This long-sleeved zip t-shirt is ideal for high-intensity activities such as fell and trail running or a spin session at the local gym. The lightweight, fast-drying fabric optimises comfort whilst helping to keep you cool and your temperature regulated.
What is it made of?
Rab has constructed this zip-up t-shirt using Motiv™ Aero single jersey fabric. This material has a fine mesh structure that promotes ventilation with fast-drying and moisture wicking properties.
Moisture wicking base layers are important to help draw moisture away from the body, unlike cotton shirts which will just hold the damp in, creating a clingy, wet feeling on the skin. These types of wicking fabrics allow sweat to pass through the material, away from the skin, helping to keep you dry and allowing you to regulate your temperature by avoiding lingering cold sweat patches.
The fabric has an added odour control treatment which will also help to keep you feeling and smelling fresh all day long, great for endurance runs across the mountains or even a short morning run in your local park.
What are its features?
With lightweight, fast wicking, odour control technology, the Rab Sonic Ultra Zip is sure to be your new best friend when it comes to mountain running or high-intensity activity.
Breathability is enhanced with the fast-drying fabric and lightweight feel of the shirt, alongside the odour control treatment for added freshness. Microactive seams are strong yet soft inside, helping to increase comfort and reduce chafing when working up a sweat.
Set-in sleeves offer a streamlined, sporty look with underarm panels containing laser cut vent holes for optimised ventilation. The technical design promotes maximum ventilation, making this an ideal all-round piece of kit, suitable for both the gym and challenging outdoor pursuits.
Further laser cut vents sit at the back of the neck, alongside a deep, centre front zip for improved ventilation across the upper body. Reflective branding finishes the design, perfect for campers or those who like to exercise after dark.
How does it fit?
The Sonic Ultra Zip comes in a slim fit, meaning it will hug the body a little closer, helping to keep out that pesky breeze, holding warmth in once you've reached the summit.
Where does it fit in the layering system?
This long-sleeved t-shirt performs best as a base layer due to its slim shape, moisture wicking properties and improved ventilation.
It’s ideal for exploring warmer climates or a midsummer jog. You can also layer it underneath fleeces and coats during the winter as a cosy, breathable, versatile, base layer.
