2012 Ibex El Fito 3/4 Bib.Heavy-duty bib for heavy-duty cycling. Merino Wool, nylon and Spandex make up the bottom, with polyester and Spandex on the seat and inner thigh. 4-way stretch, 13 panel construction.The built in Chamois is ultra comfortable. I'd rate it as a medium thickness. The Ibex Chamois is cut so perfectly it disappears beneath you (as it should).I have an entire season of hard riding on this Bib from road to cross to mountainbiking. This is one tough pair of Bibs I tell you. I hand wash them after the ride. They are dry in the morning.I can't rave enough about this product! I have a few Ibex garments and I'm very pleased. We at Down Cycles fully stand by our choice pick products. This Bib is what I reach for when the temps dip down into the 30's and 40's.If you like this Bib then check out the Ibex Zepher Beanie!PROUDLY MADE IN THE USA (in VT)!
