I have to admit, even though I've been happy with every Velocio product I've ever bought, I'm a bit "value oriented" for everyday use so only look to these for those infrequent and truly special rides.
This base layer, though, has blown me away. I ride year round into "polar vortex" extremes, often doing 3+ hours in sub freezing temps and have lots of very nice base layers for 20-30% less cost. I tried this out on the first of 5 100k "festive500" rides and refused to send it to the laundry hamper, insisted on wearing it 5 straight days/rides.
It's insanely soft, feels luxurious. You'll hate to take it off. Fit is a bit loose, not compressive.
Warmth is obviously dependent on selection of outer softshell, but I was able to use this plus appropriate jacket for 3+ hour rides down in <20f days, up to 45F and was completely comfortable. Over 40 I sweated a bit, this breathed well but did end up a bit damp, but next morning was dry, no stink, ready for another ride.
I've got Velocio bibs, jersey, gloves, socks, love them all (though have to hide the credit card statement) and despite the price am happy to rate them 5 stars. Based on that baseline and the fact that this base layer is competitively priced, I'd need to give this at least 7-8 stars.
Riding in miserable weather doesn't have to be a miserable experience, and this is far and away the best winter riding purchase I've ever made. Feels amazing, performs brilliantly, and is versatile enough that it works for just about every winter/fall ride. Even looks great off the bike.
