I bought a Buffalo Teclite last year for winter cycling and it has been my go-to item of clothing for everything ever since. I thought it would just be a cold weather jacket but I’ve worn it all year, even on summer evenings.
After a lot of research I concluded most people go for the Special 6 or Mountain shirts and then say they are too warm most of the time so never use them for active stuff. The Teclite has all the same features and ventilation but is much lighter and has a thinner fleece layer.
It’s great on the bike when it’s below 10 degrees, worn against the skin. For sub zero I add a merino baselayer.
Paramo stuff is similar but more expensive. The Paramo front pocket/vent situation isn’t as useful (you can’t use the handwarmer pocket without opening the cooling vents!) and the ‘waterproof’ aspect is no different to a Buffalo that’s been treated with Nikwax.
The Montane Extreme jacket is far too warm to ride in and very heavy, but would be fantastic if you were stuck on a mountain side in a blizzard!
