Ever grabbed a hoodie on a cold morning, only to realize it doesn’t keep you warm enough? If you’ve heard of 350 GSM hoodies and wondered if they provide sufficient warmth, you’re not alone.
Yes, a 350 GSM hoodie1 is warm. With its thick, dense fabric, it provides excellent insulation, making it suitable for colder weather. It balances warmth and breathability2, making it a popular choice for winter and outdoor activities.
But what makes a 350 GSM hoodie warm, and how does it compare to other hoodie weights? Let’s dive in.

What does 350 GSM mean?
You’ve probably seen the term "350 GSM" on clothing tags—but what does it actually signify?
350 GSM stands for Grams per Square Meter, indicating the fabric’s weight. A 350 GSM hoodie is relatively thick, offering substantial warmth and durability compared to lighter fabrics.
Understanding GSM helps you anticipate how warm and comfortable a hoodie will feel.
The relationship between GSM and warmth
GSM directly influences warmth because heavier fabrics contain more fibers, which trap heat more effectively.
- Low GSM (200–280): Lightweight, breathable, and suitable for warmer weather.
- Mid-range GSM (280–350): Offers a balance of warmth and breathability for transitional seasons.
- High GSM (350–450): Thick and insulating, ideal for cold weather.
A 350 GSM hoodie sits on the higher end of the mid-range category, making it an excellent all-rounder for cold conditions.
Visual and tactile characteristics of 350 GSM
When you hold a 350 GSM hoodie, you’ll notice:
- Dense texture: The fabric feels thicker than a lightweight hoodie.
- Firm structure: It holds its shape well and doesn’t drape loosely.
- Softness: Depending on the material, it can feel smooth like cotton or plush like fleece.
So, if you’re looking for a hoodie that feels solid yet comfortable, 350 GSM is a great choice.
Is a 350 GSM hoodie good for winter?
Wondering if a 350 GSM hoodie can handle winter’s chill?
Yes, a 350 GSM hoodie provides sufficient warmth for mild to moderate winter conditions. In colder climates, it works best as a mid-layer under a heavier jacket.
Let’s break down why it performs well in winter.
Why 350 GSM works for winter
- Thicker fabric: Traps body heat, reducing heat loss.
- Tighter weave: Prevents cold air from penetrating.
- Material options: Cotton blends or fleece add insulation.

When 350 GSM isn’t enough
While 350 GSM is warm, extreme cold requires heavier options. For temperatures below freezing, consider hoodies with 400+ GSM or wear layers for added insulation.
| Temperature Range | 350 GSM Hoodie Suitability |
|---|---|
| Above 10°C (50°F) | Perfect for warmth without overheating. |
| 0–10°C (32–50°F) | Works well with a base layer underneath. |
| Below 0°C (32°F) | Requires additional layering. |
So, if you live in an area with mild winters, a 350 GSM hoodie alone will keep you comfortable.
How does fabric type affect the warmth of a 350 GSM hoodie?
Not all 350 GSM hoodies feel equally warm. Why is that?
Fabric type affects the warmth of a 350 GSM hoodie. Cotton is breathable but less insulating than fleece, while polyester blends retain heat better and wick moisture efficiently.
Let’s explore how different fabrics influence warmth.
Cotton hoodies (350 GSM)
Cotton is soft, breathable, and comfortable. However, it doesn’t trap heat as effectively as synthetic fibers.
- Best for: Mild winter conditions or indoor wear.
- Warmth level: Moderate.
- Breathability: High, making it suitable for layering.
Fleece hoodies (350 GSM)
Fleece, often made from polyester, excels in heat retention thanks to its plush texture.
- Best for: Cold outdoor activities.
- Warmth level: High due to air pockets in the fabric.
- Breathability: Moderate; can cause overheating during physical activity.
Cotton-polyester blends (350 GSM)
Blends combine cotton’s comfort with polyester’s durability and insulation.
- Best for: Versatile wear across various temperatures.
- Warmth level: Balanced.
- Breathability: Moderate to high, depending on the blend ratio.
| Material | Warmth Level | Breathability | Best Use |
|---|---|---|---|
| 100% Cotton | Moderate | High | Mild winter, indoor wear. |
| Fleece | High | Moderate | Cold outdoor conditions. |
| Cotton-Poly Blend | Balanced | Moderate-High | Everyday, year-round wear. |
So, when warmth is the priority, fleece is your best bet.

How does a 350 GSM hoodie compare to other weights?
You might wonder how 350 GSM hoodies stack up against lighter or heavier options.
A 350 GSM hoodie is warmer and thicker than lightweight hoodies (200–280 GSM) but more breathable and versatile than heavyweight hoodies (400+ GSM).
Let’s see how it compares.
Lightweight hoodies (200–280 GSM)
- Pros: Breathable and flexible.
- Cons: Not warm enough for cold weather.
- Best for: Spring, fall, and activewear.
Midweight hoodies (280–350 GSM)
- Pros: Versatile and suitable for most weather conditions.
- Cons: Might feel heavy for indoor or summer use.
- Best for: Year-round casual wear.
Heavyweight hoodies (400+ GSM)
- Pros: Extremely warm and durable.
- Cons: Bulky and less breathable.
- Best for: Harsh winters and outdoor activities.
| Hoodie Weight | Warmth Level | Typical Use |
|---|---|---|
| 200–280 GSM | Light | Summer evenings, gym wear. |
| 280–350 GSM | Moderate | Everyday wear, mild winters. |
| 350–400 GSM | High | Winter, outdoor activities. |
| 400+ GSM | Very High | Extreme cold and outdoor work. |
A 350 GSM hoodie provides the ideal middle ground for most people.
Is a 350 GSM hoodie breathable?
Warmth is essential, but breathability matters too—especially if you wear your hoodie while active.
A 350 GSM hoodie can be breathable if made from natural fibers like cotton. However, synthetic or fleece variants prioritize insulation over airflow.
Let’s explore how this balance works.
Factors influencing breathability
- Fabric composition: Cotton is more breathable than polyester.
- Knit type: Looser weaves allow more airflow.
- Interior lining: Brushed linings reduce breathability but increase warmth.
Maintaining airflow with heavier hoodies
If you want warmth without overheating, choose a cotton-polyester blend or look for hoodies with ventilation features like mesh panels.
How can you enhance the warmth of a 350 GSM hoodie?
Need more warmth from your hoodie without upgrading to a heavier one?
To enhance the warmth of a 350 GSM hoodie, layer it with thermal undergarments, choose fleece-lined variants, and avoid exposure to moisture.
Here are some practical tips.
Layering techniques
- Base layer: Thermal shirts trap body heat.
- Outer layer: Windproof jackets block cold air.
Choosing the right accessories
- Scarves and hats: Prevent heat loss through exposed areas.
- Gloves: Keep extremities warm in colder environments.
Fabric treatments for warmth
- Water-resistant coatings: Prevent moisture-induced heat loss.
- Brushed interiors: Increase insulation without adding bulk.
These strategies help you get the most out of your 350 GSM hoodie.
How should you care for a 350 GSM hoodie to maintain warmth?
A hoodie’s warmth diminishes if the fabric degrades. So how can you keep yours in top shape?
To maintain the warmth of a 350 GSM hoodie, wash it in cold water, avoid high heat drying, and store it properly to prevent stretching.
Here’s a care checklist.
Washing and drying
- Use cold water: Hot water breaks down fibers over time.
- Gentle cycle: Minimizes mechanical stress.
- Air-dry when possible: Heat from dryers can shrink cotton and reduce insulation.
Storage tips
- Fold, don’t hang: Hanging stretches the fabric.
- Keep away from moisture: Damp storage encourages mold growth.
Regular maintenance
- Check for pilling: Use a fabric shaver if needed.
- Inspect seams: Reinforce loose stitching to extend the hoodie’s lifespan.
Proper care ensures your hoodie retains its warmth for years.
Conclusion
A 350 GSM hoodie offers reliable warmth for most winter conditions. Its medium-heavy weight strikes a balance between insulation and breathability, making it perfect for mild winters, outdoor activities, and everyday wear. While fabric type and layering can affect warmth levels, a 350 GSM hoodie generally provides the cozy comfort many people seek when the temperature drops.
