On test with me:

The Sonic T-Shirt comes in two styles, short and long sleeved and both are made from the same Apex-Dry lightweight fabric, perfect for this time of the year in the summer heat-waves.
The Apex-Dry mesh that runs along the sides, running below the arms helps to keep the body cooler.

The Sonic T-Shirt is a comfortable fit, in this review I was wearing the medium in black and the shirt was comfortable and well fitted, less of an athletics fit and more loose fitting and good length.

On the right arm and back of the neck are two smaller reflective tabs which are small and a little pointless in a safety aspect and more a feature of detailing. As a whole the T-Shirt is great for long expeditions, hiking and very well suited for running, in all these activities I have found the loose fitting great in warmer weather even despite the colour of the shirt.


The relaxed, loose fitting I found more comfortable whilst running during the day, this allowed more movement of air between the fabric and body. However many will prefer the athletics fit for further comfort and ease whilst running.

In my opinion the shirt remains subtle in its styling and doesn’t scream out to be a specialist activities T-Shirt, several times I opted to wear the T-Shirt in hot weather around light walks and office.

When wearing a rucksack the T-Shirt also remained very comfortable to wear and in the heat the back and lightweight, anti-static material kept the shirt from getting sweaty and sticking which was very pleasing. The same again whilst wearing jackets in strong winds or cooler evenings.

On the longer hikes the lightweight shirt was great with it only coming in around 90g, the quick drying material to makes it a worthwhile option on any summer expedition or those who enjoy going lightweight on exped.

If you enjoy trail running or running as a whole again this shirt is a great option for those who enjoy the sport in summer or even other activities such as Tennis, Badminton and other indoor sports. The mesh that runs along the high sweat areas makes the T-Shirt perfect for sports as a whole!

When I first started wearing the shirt I did find the seams around the fabrics and mesh a little itchy on the back. However this was easily fixed by washing the T-Shirt prior to continued use, after which the shirt was very comfortable to wear for long periods of time in hot and cold conditions.

Although the seams were itchy at first, the fabrics used were not and are soft to the touch even in the heat and when the top is wet. The material is quick drying which makes is more favourable to those hiking.

What I found very beneficially and a great addition for a summer sports shirt like this is the UPF protection 50+ making it excellent and reduces the UV rays from passing through to the skin. As someone who often uses factor 50 sun cream and insists on DofE and Scout groups out on expedition to wear sun cream having more items of clothing offering extra protection from the sun is welcomed!

The shirt also benefits from POLYGIENE odour control, along with the mesh sides the two work hand-in-hand to make running a joy. The Polygiene helps reduce the smells of sweat and the mesh sides reduce sweat to allow air movement into the hotter areas of the body. The question is, why wouldn’t you want this whilst running or any sports for that matter.

As a whole I found the Montane Sonic T-Shirt an ideal and all round beneficial T-Shirt to keep with me on expedition or whilst out running. The shirt being lightweight and quick drying makes it perfect for this time of the year.
The breathable mesh along the body started off being itchy but after a wash caused no problems after and the shirt remained and continued to be comfortable in all weather conditions. Especially in the heat!

A highly suitable summer activities and sports T-Shirt for all year use, especially for those on long expeditions, hiking and running.
