If you’re into hillwalking, scrambling or climbing in the UK, finding the right mid-layer can be tricky. You need something that’s warm, but not too warm. Breathable, but still protective. After trying out the Patagonia Nano Air Ulstraight Hoody, I think it ticks a lot of boxes for active days out in the British mountains. Here’s what I’ve found.
Why choose the Patagonia Nano Air Ultralight Hoody for climbing and walking in the UK?
The Patagonia Nano Air Ultralight Hoody is designed for people on the move — literally. Whether you’re climbing in the Lakes, trekking in Snowdonia, or walking in the Cairngorms, it’s a very lightweight mid-layer that balances warmth and breathability really well.
It’s made with stretchy, weather-resistant fabric and 30% less insulation than the original Nano Air. This means it doesn’t trap too much heat, which is exactly what you want when hiking uphill or climbing routes that keep your heart rate up. Even in cooler UK weather, it helps regulate your temperature during activity.
You also get 75% more breathability compared to the original model. If you’re sweating on a climb or going fast up a ridge, this is a huge plus. It’s designed to keep you comfortable without needing to stop and layer up or down all the time.
Is the Patagonia Nano Air Ultralight Hoody worth the money?
At around £140 (on offer) , the Nano Air Ultralight Hoody isn’t cheap. But if you’re regularly out in the hills or on mountain routes, it could be a good investment.
Build quality is high, and the minimalist design means fewer zips and features to go wrong. Patagonia also offers great aftercare, which adds peace of mind when spending this much on a jacket.
For people who want a versatile and durable midlayer for active use, I’d say yes — it’s worth it.

When to use a Patagonia Nano Air Ultralight Hoody in the UK
The Nano Air Ultralight Hoody works best as a mid-layer for active days, especially in:
- Spring to autumn mountain walking
- Cold-weather scrambling or climbing
- Chilly mornings or breezy ridgelines
- High-output activities where you’re moving fast and don’t want to overheat
It layers well over a base layer and under a shell if it’s raining or very windy.
When NOT to use a Patagonia Nano Air Ultralight Hoody in the UK
There are times when the Nano Air Uktralight Hoody isn’t the best option, such as:
- Winter belaying or standing still on cold, exposed summits – it’s not warm enough on its own
- Heavy rain or snow – it’s water-resistant, but not waterproof
- Everyday use around town – it’s a technical piece and lacks handwarmer pockets
It’s a great piece of performance kit, but not designed for sitting around or harsh weather on its own.
