Discreet warmth for cool fall days.

Giro's New Road collection has gone to great lengths to cater to female cyclists, with each women's release either coinciding with or even preceding its men's counterpart. The same holds true for the new-for-2014 Giro Thermal 3/4 Leggings. These leggings feature a wool blend, which appeals to our love of cycling eras gone by, and a level of utility you'd expect from a contemporary cycling garment.

With their woolen construction, these tights aren't just relying on nostalgic appeal. There are many people around the Competitive office who pair their cutting edge lycra kits with wool-blend arm and knee warmers, because, when it comes to staying warm, wool is tough to beat. The Thermal Tights take advantage of that. If there was a more effective solution to be found in today's cycling technology, Giro would not doubt have incorporated it, as evidenced by the inclusion here of a premium CyTech Carbon chamois. CyTech manufacturers almost any chamois in the world worth sitting on, so you can rest assured knowing that your nether regions will rest assured in the saddle.

The Thermal 3/4 leggings are short enough that you can wear them discreetly under a pair of full-length pants, or wear a skirt without worrying about cold knees on a chilly ride. Stretchy bands below the knees ensure that they'll stay in place under your outerwear. The Thermal Leggings also boast pockets — a true anomaly for cycling tights and a definite plus if you're in a pocket-less skirt. This affords an additional element of utility that so-called "high-performance" offerings lack.

The Giro Thermal 3/4 Leggings - Women's are available in five sizes ranging from X-Small to X-Large in the color Jet Black.

Nice cold-weather bike pants

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Small

These are quite comfortable, and a bit thicker material for warmth. They are a hair scratchy from the wool but that may go away after a few wears/washes. The best part of them is the side pockets to stash your gummies without reaching behind or in your camelbak! I usually wear smalls but sometimes mediums in chamois, but small was good in these. Waist is a hair big but otherwise fits well!

Favorite cycling pants

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XS

First off, the chamois on this is really great. I initially thought it was too firm, but it holds up well and has been comfy so far for rides around 3 hours (haven't had time to take it for longer yet!) Second, they are super soft on the inside. Third, those pockets are the best. Only 2 drawbacks so far: First, they sometimes bunch up behind my knees. I have rolled them up over my knees when it gets annoying, so I feel that they either need to be shorter or longer (or I could grower taller or shorter). Second, although I never expect to look "good" in chamois, the part on the back of the pants where the chamois attaches to the pants is square-ish. So looking from the side, the chamois juts out a bit and pulls quite a bit on the material. If I had to be super picky, I would say the waist could be a tad higher as well. Overall, these are my fave cycling pants so far. I wish they made them without the chamois so that I could have a pair for running too!
