Rukka Outlast Shirt

The shirt fits well and is comfortable.
I have not really noticed the heat storage and release properties claimed. A bit of a disappointment really.
As a consequence I use other base layers in preference- Under Armour and Helly Hansen are more suitable imo.

A perfect fit and feels very comfy.
It’s currently my go to top

Order as going to Belgium in June and wanted some base layer that would keep me cool when weather warm and warm when weather cold.
Iv used a few times in 6 deg and kept me warm. Not tried in plus 20 deg yet.
But the fit is lovely and material is soft don't even know you have it on.

Really good fit, excellent quality and works really well at regulating your body temperature.

Good layer warm and comfortable
a good buy in my opinion

Works really well.
Very comfortable.
Great quality.

Bought this base layer somewhat sceptically, as it was meant to keep you cool in the heat and warm when it gets cold. It really is comfortable and has been my go to shirt virtually every ride.
It really seems to work well, within certain tolerances.
I have bought another !!

I wasn't expecting much from this, but whether the weather is good or bad it adjusts accordingly.
Really impressed. Honestly folks, buy this.

Now used twice, once on a cool and wet ride and once on a hot and sticky day. On both occasions the garment did it's job in keeping me warm or cool. Really nice & comfortable to wear. Worth the cost over cheaper less effective garments.

Really comfy to wear, nice material, probably the best top I've bought

I went for a short road trip to France and wanted something to go underneath my Knox armoured shirt.
This was perfect. The best bit? The sleeves are super long (I have monkey arms!) though the back could do with being a little longer.
And of course the service from SBS was the usually high standard.

Purchased with long johns & currently European tour of 9 countries in all weather from rain snow to 26 c sun
Awesome performance & quality so comfortable bone dry and quality product best bike related purchase by far & will use for other pursuits

Comfortable and does what it says.

Very comfortable and quality product

This is the third time I have purchased one of these shirts. They are very comfortable and effective in hot or cold conditions. Have tried merino but find it irritated my skin, this works just as well and much more comfortable. Great product.
