Castelli LW (Lightweight) Cycling Bib Tights - AW18


The Castelli LW (Lightweight) cycling bib tight has been designed specifically for light winter conditions on day when you still need the protection of a full winter tight but perhaps not to a level where you feel restricted by and ultra-thick deep-winter bib tight. Providing a moderate amount of protection from wind and rain the Castelli LW bib tight is made from a clever combination of Thermoflex and Nano Light fabric to offer adequate wind and water resistance while keeping you feeling warm and protected from the elements. Thanks to their lighter weight construction and capacity for stretch the Castelli LW bib tights offer an enhanced freedom of movement on hard winter training sessions and the inclusion of a brilliantly comfortable Progetto 2 Air Seat Pad means that you’ll be able to ride further, for longer.



  • Thermoflex fabric for exceptional warmth, stretch and breathability
  • Lower panel in Nano Light fabric for splash protection
  • Lighter-weight bib tight for light winter conditions
  • Progetto X2 Air seat pad for long-distance comfort
  • Mesh bib straps
  • Reflective viz strips for visibility
  • Suitable for a temperature range of 6°-12°C



Nice materials, really comfortable pad, and great weight - perfect for 6-18ºC temps. Some "furring" seems to have occurred under seat area after first couple of rides ... need to keep an eye on that but think it will be ok. Other slight negative - shoulder straps are a tiny bit short for me. I am 180cm, strong/swimmer/sprinter type build weighing 78kg - bought a medium, they do fit nicely everywhere else but feel I would benefit from 1-2 cm extra length in the shoulder straps. Nothing painful, just a touch tighter than I would like. Overall very happy though ... perfect weight for my winter riding here in the Algarve and generally very comfortable
Brlliant bib tights. The leg meterial is very thin and very stretchy (enough that no zips are necessary), can feel a bit cool in the first few minutes of a 10C ride, but plenty warm enough within minutes, once youv'e warmed up a bit. With an appropriately tight fit, no intrusive seams or stitches and no bunching-up whatsoever behind the knees, you forget they're there. Perfect pad (for me anyway) - unintrusive and comfortable. The 'rubberised', splash-resistant lower leg section works a treat, and can easily be wiped clean - clever and effective. The sizing doesn't run as small in my experience as some have reported: medium is perfect for a slim(ish)-built 5'9". The straps feel rather tight when standing up straight, but perfect once in the riding position. Great service from Merlin, as usual.
Very warm. 1.73 and 80 kg, size XL
