Product Customer Reviews

One of the worse base layers I have every purchased. Very short cut plus no stretch. The material is scratchy and very thin.
Bad quality!
I LOVE that layer shirt: it's comfortable, and will keep you warm! Love it so much I ordered a second one. But be aware that it fits very VERY small. I order a Mens Large and I usually wear a Womens' small or medium per US sizes.
Warmish
Not too snuggly
Comfortable
Excellent value for money. I went back and bought another 1.
Great under work shirts during the winter months.
Perfect in winter
good value for money
Urticant in side around the neck and shoulder
Works really well but the sleeves are a little short.
Wear it all the time
I bought to use on my motorcycles under my jackets, it great , warm, thin, lightweight and not bulky under the jacket which gives ease of movement
This is very warm but runs very small. Too small for my husband but I’m wearing it!

Additional Product Information
Composition
Main fabric: 100.0% Polyethylene Terephtalate
What is the fit of the simple warm base layer?
The Simple Warm base layer has a REGULAR cut.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?
You just need 3 technical layers to keep warm on the ski slopes:- Layer 1 or a 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 ABCDE score is given to help you easily identify products with the best environmental performance by comparing products of the same type (T-shirts, pants, backpacks, etc.).
Product testing
All Wedze products are created, designed, and developed in the Mont Blanc Valley. They are then tested under the same conditions as you would experience in real-life use (snow, cold, powder snow, etc.). The design teams ensure that the program for which the product has been designed and developed matches perfectly with its use in the field.
