If you’re anything like me, a brisk morning run is the perfect start to the day. But let’s face it, the British weather isn’t always our friend. So, when I came across the Sweaty Betty Therma Boost Running Zip Up, I had to give it a go. Priced at £130, it’s certainly an investment, but as we all know, quality gear can make all the difference in our workouts.
First things first, the size range is pretty inclusive, running from XXS to XXL. Finding the right fit is super important for comfort and performance, and it’s great to see a brand catering to a wide range of body types.
Now, let’s talk fabric. It’s made with 76% recycled materials, which is a huge plus for me. We all want to do our bit for the planet, right? Plus, it’s warm, sweat-wicking, and breathable. I mean, what more could you ask for in a running layer? It’s the kind of fabric that feels light but keeps you toasty, without turning you into a sweaty mess.
The fit is snug and flattering, thanks to the contouring seamlines. It hugs in all the right places, making you feel sleek and streamlined as you hit the pavement. The full body zip is perfect for adjusting ventilation – zip up when you start off in the chill, and gradually lower it as you heat up.

But here’s the real game-changer: the reflective seams and detailing. For early morning or late evening runs, this is a safety feature that I really appreciate. It’s subtle, but effective, making sure you’re visible to others.
And let’s not forget those little details that make all the difference. The long sleeves with thumb holes are a personal favourite. They add that extra bit of warmth, especially for your hands, and they ensure the sleeves stay put, which is super handy when you’re on the move.

So, is it worth the £130? In my opinion, absolutely. It’s a versatile, high-quality piece that not only supports your running regime but also contributes to sustainable fashion. Whether you’re a seasoned runner or just getting started, the Sweaty Betty Therma Boost Running Zip Up could be just what you need to elevate your running game this season. Stay warm, stay visible, and most importantly, stay running! Visit the Sweaty Betty website here now to shop.
