My favourite base layer bottoms
5 out of 5

I prefer these RAB Flux base layer bottoms to other pairs that I have which are made of merino wool.
These feel great against the skin, trap warm air in and keep cold air out. Perfect.

Awesome pants! All I can say is that Ken from the previous review is a brave man wearing these with no underwear! But I’ll give it a go!

Fantastic pair for pants,...
5 out of 5

Fantastic pair for pants, I’ve worn mine many on their own, ideal for the cooler summer days, but also they’ll be ideal for a base layer pant come winter.
Feel great on, I wear without underwear, but if your a wee tad bashful then underwear is advisable.
