Best Cold Weather Running Gear for -15°C
Running at -15°C on the frozen Rideau Canal in Ottawa gave me the chance to test a simple cold weather layering system for sweaty runners.
Tested During a Run on the Frozen Rideau Canal
Run Stats:
Distance: 11.85 miles
Run Time: 2:04 – (Elapsed time 3:25 plenty of stops for pictures)
Temperature: –15°C (–18 wind chill)
Surface: Frozen canal ice, snow trails, icy pavement
Footwear: Normal running shoes (no Yaktrax)

Most of my running happens in the UK, which means winter usually means wet, muddy, and windy rather than genuinely cold.
So when I had the chance to run in Ottawa at -15°C, it was the perfect opportunity to test how well a simple cold-weather layering system would perform over a 2–3 hour run.
The route followed the frozen Rideau Canal and looped around Dow’s Lake, creating one of the most memorable winter runs I’ve done.
The key challenge in conditions like this isn’t just staying warm — it’s managing sweat. As a runner who sweats a lot, the wrong clothing system can easily lead to overheating early in the run and freezing later.
For this run I used the following gear:
- Arcs Merino Baselayer
- Helly Hansen Men’s Lifa Merino Midweight Hoodie
- Thermal Running Tights
- Tough Headwear Balaclava
- Montane Respond Insulated Gloves –
Here’s how everything performed.
Quick Verdict
Best Base Layer: Arcs Merino Baselayer
Best Mid Layer: Helly Hansen Men’s Lifa Merino Midweight Hoodie
Best Running Tights: Thermal Running Tights
Best Face Protection: Tough Headwear Balaclava
Best Hand Protection: Montane Respond Insulated Gloves
This simple system handled -15°C for over two hours of running without overheating or getting cold.

Base Layer-
Arcs Merino Base layer Review

Why Merino Wool Works for Runners
Merino wool is one of the best fabrics for endurance sports in cold weather because it:
- Regulates temperature
- Wicks moisture
- Stays warm when damp
- Resists odour
For sweaty runners, this combination makes a huge difference.
Performance on a -15°C Run
This baselayer did most of the hard work in the layering system. Even once I warmed up during the run, the fabric managed moisture well and prevented that cold clammy feeling that can happen with synthetic fabrics.
After 2–3 hours outside, the temperature balance remained comfortable.
Pros
✔ Excellent temperature regulation
✔ Great moisture management
✔ Comfortable fabric
Mid Layer –
Merino Hoodie Review

Why a Merino Mid Layer Works
Layering is critical in cold conditions. The merino hoodie provides lightweight insulation without trapping too much heat.
On the Run
Worn over the merino baselayer, this created a really effective two-layer system that handled both steady running and slightly harder efforts.
It provided warmth when needed but never felt too heavy or restrictive.
Pros
✔ Breathable insulation
✔ Lightweight warmth
✔ Versatile hood
Running Tights –
Thermal Running Tights Review

Why Thermal Tights Matter
Your legs generate a lot of heat when running, but in very cold conditions a standard pair of thin running tights can still feel chilly — especially if there’s wind.
These thermal tights provided the right balance of insulation and flexibility for sustained running.
Performance on the Run
Even running alongside the frozen canal with exposed wind sections, my legs stayed comfortable throughout the run.
They were warm enough for -15°C conditions but still breathable enough that they didn’t feel overly hot once fully warmed up.
Pros
✔ Good insulation for cold weather
✔ Comfortable stretch for running
✔ Lightweight feel despite warmth
Cons
- Might feel too warm for milder winter conditions
Head and Neck –
Tough Headwear Balaclava Review

Why a Balaclava Matters in -15°C
When temperatures drop this low, your face and neck are the first places to feel it. Cold air hitting your lungs can feel harsh and exposed skin cools quickly.
The Tough Headwear balaclava adds just enough protection without feeling bulky or restrictive.
Pros
✔ Lightweight and breathable
✔ Flexible design (balaclava or neck gaiter)
✔ Good wind protection
Cons
- Can get warm during very hard efforts
Gloves –
Montane Respond Insulated Gloves Review

Why Gloves Are Essential in Very Cold Weather
Hands cool quickly when running in freezing temperatures, especially when there’s wind. Good insulated gloves are essential for keeping circulation comfortable.
The Montane Respond gloves performed very well during the run.
Performance on the Run
They provided good insulation while still allowing enough dexterity for normal running movement.
Even in -15°C temperatures, my hands stayed warm throughout the run.
One Small Lesson Learned
Because I was stopping frequently to take photos of the frozen canal and lake, I found myself taking the gloves off quite a bit.
Getting cold fingers back into gloves isn’t the easiest thing once they’ve cooled down.
In hindsight, mitts may have been slightly better for this type of run because they’re quicker to slip on and off and often retain heat better.
Pros
✔ Excellent warmth
✔ Lightweight insulation
✔ Comfortable fit
Cons
- Slightly fiddly to put back on with cold fingers
What to Wear Running in -15°C
Based on this run, here’s a simple layering system that works well.
|
Layer |
Example |
|
Face protection |
Balaclava |
|
Base layer |
Merino long sleeve |
|
Mid layer |
Merino hoodie |
|
Bottoms |
Thermal running tights |
|
Hands |
Insulated gloves or mitts |
This type of system allows you to stay warm without overheating, which is the key to comfortable cold weather running.
Final Thoughts
Running in -15°C isn’t something I get to do very often, but when the opportunity comes along it’s always worth getting outside and enjoying the experience.
For this run along the frozen Rideau Canal and around Dow’s Lake, the simple combination of:
- a balaclava
- merino layers
- thermal tights
- insulated gloves
worked extremely well for a 2–3 hour winter run.
The biggest takeaway?
If you’re running in very cold conditions, layering properly and choosing fabrics that manage moisture well — especially merino wool — makes all the difference.
