Arc'teryx Rho LTW Beanie

Simple, light weight Beanie
Compare to the Arcteryx Bird Head and classic Beanie, the Rho LTW Beanie feels different. First of all, its very thin and stretch well which, for me, is a plus. They do feel comfortable and cozy unlike the other 2 beanie which feels tight. Performance wise, due to its thickness, the Rho beanie doesn't provide as much warmth as the Bird head or classic Beanie. Build quality is very good and it has a simple and timeless design. I would recommend this beanie to anyone in cool weather / morning. However, it may not provide the needed warmth in cold winters

Perfect
Perfect hat for all outdoor athletics - not too heavy but definitely warm enough for most activities above 30 degrees

Always have it with me
I had it for over a year and just got another one. I use it for cycling and just around. Perhaps if you want something for very cold days with freezing wind it might be too thin. I often combine it with hood in the coldest days in Boston when I commute on a bicycle. I found it useful all year around. Good for running, very breathable, highly recommended.
