  • Midweight merino wool (260g/m²) regulates your body temperature and works well as a mid layer on cold nights or your top layer on spring and fall days
  • Merino wool is soft, non-itchy, and naturally resistant to the bacteria that causes funky odors
  • Lycra fibers give the merino material a flexible stretch for mobility and comfort
  • Mesh underarm panels improve ventilation and help you stay cool where it's easy to get overheated
  • Underarm gussets allow for a wide range of motion and easy movement
  • Flatlock stitching eliminates the bulges that cause chafing and discomfort at the seams
  • Front zipper is reflective to help you stay visible when you're running along the road at dusk or dawn
  • Drop-tail hem provides additional coverage at the back of your waist so chilly drafts can't sneak in when you lean forward to run or pedal up a steep hill

Perfect, man. Perfect!

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

Merino wool is where it's at. I have the Quantum vest, which has a little more fitted cut than this hoodie. Still athletic, but without showing your nips to the world. The monkey thumbs on the sleeves are probably good if you have a 33"-34" sleeve. I'm 6"2', 185 lbs, 43" chest and 33" waist. The large fits me perfectly. I have 35" arms, so I just don't use the thumbholes.
This item is my new go-to midlayer, now I'm looking forward to Fall and Winter.

Top notch, you won't be dissapointed

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I have owned one of these for over 12 months now and this is my go to hoody for just about everything be it casual wear, cool weather running or a midlayer for skiing. It has an extremely comfortable fit, breathes and wicks moisture like a beast and you just can't beat Merino wool. I wore this jacket every day for 2 weeks straight snowboarding in Japan and there was not any smell at all!

This jacket is amazing

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

I bought this for my husband for Christmas. It is very soft, thin but very warm! He loves it. It's worth the money!

Incredibly versatile

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Just back from a five-day, 1200 mile motorcycle trip chasing corners from Pittsburgh to Southwestern Virginia and back. Temperature ranges as varied as the terrain and road conditions. From 80s in the valleys in bright sunshine to 25 miles of 48 degree, fog-bound creeping along the Blue Ridge Parkway to the 56 degree high-speed jaunt home on Monday. I never took this hoody off once (other than to shower). Thin polyester long-sleeve underneath when it was hot and light insulated vest on top when it was cooler. Never too hot and never once cold. I've always been a fan of merino wool since my first really good cycling shorts in the 1970s. The new clothing applications are outstanding and this is a great example. I'm 6', 215lbs, long-waisted and the XL is perfect. And it never smells!

Amazing Hooded Full zip shirt!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I absolutely love wearing this shirt whenever I go out for casual dressed functions. It keeps me warm and allows me to pair it with a nice icebreaker t so I don't sweat in hotter conditions. If you want style and comfort all at the same time choose this option and you will never be disappointed! One word of CAUTION: Never machine dry this garment! Always hang dry! I am 6'2", athletic build, and I wear a large

Eric, just based on the fit, would you say I should go with a medium or large? I am 6'1 175, thanks.

Responded on

I am actually right in that range and would definitely say a large is the best way to go. A medium would be way too short.

Wide Temperature Range Midlayer

  • Familiarity: I've put it through the wringer

I have had one of these hoodies for a year and have been inpressed by how well it regulates body temperature. I have worn it running on mornings that start cool (mid forties) but remain comfortable well above those temperatures. This jacket does just as well on bitter days, keeping me comfortable well below freezing. I love the athletic fit and the soft feel of the wool. It also dries quickly enough that I can wear it on a high tempo ride into work, and it won't feel damp on the way home.
