Casewrote a review of Assos TiburuGiletEquipe - Men's on February 20, 2018
Familiarity: I've used it several times
This vest is great for intermediate temperatures or the photographers golden hours on the bike (sunrise or sunset). I find it most comfortable in the 55-70 degree range and paired with the some type of long sleeved base layer underneath. As with the Tiburu jacket there is not much actual insulation in the vest, so if you wear it against your skin you will get cold, though the base layer, ride tempo and terrain will have a big impact on how comfortable you feel. I find this more true with vests than with jackets, so your experience may vary.
Fit is typical assos: snug but not tight, and very comfortable on the bike. I think it looks pretty good in black.
I quite like this vest and recommend it, but it gets four stars because I think it's not very good value for money, especially because it is best combined with a base layer, and also because in my opinion it is not very good when worn over a jersey. There are other gilet options that will provide better insulation, and will also provide better weather protection. I wear long sleeves or arm covers on every ride (very sun sensitive), so a vest plus base layer is appealing to me, but I am not sure that this vest really fills a need unless you are like me and want another long-sleeve option in the locker.
