Product Customer Reviews

I was sceptical but was delighted by the warmth it gave. I am a large (6'1" - 200lbs) usually, but due to stock outage I selected an XL. Glad I was forced to make that choice ! It is snug - but comfortable. It sure did the trick. I did wear it under a full polartec undergarmet and it gave me the extra warmth at 90' that I was previously missing.
Love your products but I wish you'd sort your sizing out. I'm a size M in pretty much everything I buy, but I think this was around two sizes two small - I couldn't breathe when I put it on. I'll reorder in another size though as it seems like a really good top.
The top looks and feels very nice and fits well. Will have to wait t try it out on the slopes though.
Golf thermals don’t do the job. This does but doesn’t have fancy logos.
není co dodat úolně perfektní
tepelná pohoda i odvod potu je velmi dobrý. srovnatelný s výrazně dražšími produkty. Komprese je vyhovují. Doporučuji.
Plní vše potřebné i při VHT. Délka vyhovuje a dobře kreje záda i při náročnějším pohybu.
Sehr zufrieden

Das Unterhemd paßt hervorragend, ist weich und hält schön warm. Für den Preis empfehlenswert.
Ich habe mir das langarmshirt zum Biken zwischen 0 und 5 Grad unter einer dünn isolierten Radjacke geholt. Es wärmt gut, aber nicht extrem, dadas Gewebe auch sehr atmungsaktiv ist. Ich hatte keine Probleme mit Hitzestau oder Ähnlichem. Die Verarbeitung wirkt ziemlich gut, der Stoff ist sehr elastisch. Es erfüllt den von mir gewollten Effekt. Allerdings würde ich empfehlen eine Nr. größer zu bestellen. Ich bin 1,80 und mit 63 Kg sehr schmal. Normal passt mir überall M mancmal sogar S. Hier habe ich M/L bestellt und es passt gerade so. liegt sehr eng an auch am Hals und die Ärmel sind fast ein wenig kurz. Es gibt echt wenig Klamotten in M, die an meinem Körper hautdirekt anliegen :-).
Nutze es mehrfach die Woche, hält sehr warm erlaubt aber trotzdem das schwitzen. Sehr gelungen!
Trage ich beim Biken unter der Jacke. Super Tragekomfort, hält warm und ist atmungsaktiv.
Hält super warm und macht jede Bewegung mit.

Size Guide

Additional Product Information
Composition
Main fabric
- 3% Spandex
- 17% Polypropylene
- 80% Polyamide
What type of fit is the 900 base layer?
The 900 base layer comes in a slim fit. It is a 2nd skin with a slim fit that reduces friction.
What are the advantages of polyamide and dry yarn fiber?
Polyamide has the highest strength of all textile raw materials (even when wet) and is very stretchy. It's a breathable fiber that manages moisture very well and provides good temperature regulation.. Blended with polypropylene or dry yarn, this hydrophobic yarn promotes extremely good perspiration wicking.
Technical structure of the product
Thanks to the intelligent 3D knitting, deep insulation compartments are formed. These are insulating chambers that trap warm air coming from your body to create a buffer against the cold.
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 the elements.
