Got the pants as well I would recommend these to anyone, extremely comfortable and warm.
Great base layer, super warm and not too bulky! Love it, can’t wait to get the leggings when they’re back in stock!

so comfortable and easy to wear for long tome
I really love the inner side of this top, very soft material. Wearing this when going out make my body warm.
Great product came back to buy more
I bought these with the matching leggings and bought the children’s set for my son for a trip to Sweden and they were amazing! We went skiing in -17 degrees Celsius and they kept us warm and dry and I love the snuggly fleece Lining. Would buy again and no way would I spend more anywhere else.
A snug fit, comfortable and warm.
It has a high turtle neck, not what's pictured. Unfortunately I need them for tomorrow, otherwise I would be returning.
Good fit. Kept me warm and dry
Warm & cosy
Fantastic for my ski trip, warm, breathable and great value for money.
Lovely warm and comfortable to wear and feels light
Warm and comfort in one
This base layer is lightweight whilst being warm and cosy. Easy to wash and dries quickly. My favourite base layer for all outdoor sporting activities
Additional Product Information
Composition
Main fabric
- 100% Polyester cationic
What is the fit of the simple warm base layer?
The Simple Warm Base Layer comes in a regular fit. It is a classic straight cut that adapts to all body shapes.
What are the benefits of polyester?
Polyester is the most-used fiber for base garments because it is relatively inexpensive and offers excellent performance in various respects, and especially because the fibers can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet. It is limited in its ability to reduce odors.
How to dress to stay warm on the slopes?
All you need is 3 technical layers to stay warm on the ski slopes. Layer 1 or 2nd skin, to stay dry. Layer 2 or an insulating layer, to keep the heat in. Layer 3 or a protective layer, to protect against bad weather.
A product-specific environmental rating
The environmental impact of the product is calculated over its entire lifecycle and using various indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, pants, backpacks, etc, ...).
Determining the environmental impact of our products: recycled polyester
By recycling plastic bottles or textiles to produce our polyester, we reduce the use of petroleum-based resources while keeping the material's breathability in practice.
Determining the environmental impact of our products: dope dye
Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this environmental impact, we opted for a bulk dyeing process that involves adding the color pigments when the yarn itself is being produced.

Imported
