The Velocio ZERO Bib Tight pairs thermoroubaix fleece with a windproof softshell front panel to handle the coldest rides of the season. The rear fleece traps heat while the front panel blocks wind where it hits hardest, so we stay warm without extra bulk. Updated bib straps hold the fit secure through a full winter pedal stroke. What Our Gearhead® Experts Are Saying:"I've worn these on sub-40 degree mornings and never reached for a base layer underneath. The softshell front panel cuts the wind at my knees before it reaches skin, so the fleece only has to hold onto heat, not fight incoming cold."
