Since I got my Ninja Road Warrior 4-season jersey last week, I have only taken it off to go to sleep at night. It's become my second skin both outside in the Seattle winter and inside at high-temperature parties. It seems to adjust to the temperature immediately. The hood, zipper and pockets are all in just the right spot with just the right line. The hemline is like pure magic with just the right extension at the back for leaning over during riding without looking too droopy off the bike.

This is my favorite article of clothing possibly ever.

Thought I would leave a little comment about the 4 season jersey I just bought off of you guys. I was kind of skeptical of the merino wool at first, but I have since tested it against cotton, fleece and other warm weather clothes. It holds up great for warmth as a base layer for now. Can't wait to test it in warmer months. I'm throughly enjoying it, I really never take it off.

I've been wearing the heck out of the ninja for about 3 months now and I think it's an excellent jersey.

It's an incredibly versatile garment that I can wear alone in the late summer, layer over a light wool t-shirt in September, over a long sleeved wool tee in October, and I'm now using it as a middle layer under heavier layers for the winter.

Having the hood attached makes it easy to flip it, zip it, all on the go, and be warm and happy when the wind picks up on a ride.

I got one in the charcoal merino, and it is great. The fit is just right for me in size large. It is comfortable, and well detailed. I wore it to work today and women told me how nice it was.

Meant to write yesterday.... The jersey arrived yesterday--safe, sound and most certainly perfect for what I need. It will be a great addition to the collection of "things that keep me warm" now that the cooler weather is coming.

Got the jersey today. It is beautiful.

[Later:] Just to let you know that I've been commuting in the cold with your jersey, and it is much warmer than expected. It must be the fineness of the weave, but it is warmer than any of my other wool bike jerseys. Down to -10C I'm good with the jersey, a wind jacket, and a light wool t-shirt underneath. Not cold enough to go full balaclava mode yet.

[One year later:] You can amend my testimonial as follows: rode in this morning at -13C (-23C wind chill) with a wool T shirt under your wool hoodie, a helmet, and a wind jacket and pants. When I bought this thing, I figured it would be at least as good as a wool balaclava plus jersey. Actually it is better; on a day like today where full balaclava mode is not necessary, I can put it over my head, unzip the slider to just under my lower lip. This way, my cheeks are still mostly covered, but I can breathe through my mouth without my glasses fogging up. With the balaclava, my only options are covering the nose, and uncovering all the way down to the chin.

Received mine today--looks and fits great--the hood is perfect.
