OVERVIEW: The High Grade is an excellent choice for those who want a natural fiber, cold weather base layer that will perform remarkably well at retaining heat, even when wet. Merino wool is known for its exceptionally soft characteristics, is naturally breathable and extremely efficient at regulating body temperature due to its great warmth-to-weight ratio. This base layer is ideally suited for pairing with our cold weather and thermal outerwear for defense against the harsh cold and winter conditions, and temperatures between 30° - 60° F.

By utilizing a blend of merino wool and polyester, it combines the best characteristics of each fabric. The result is a tight-fitting anatomical garment that is gentle on the skin yet tough enough for the washing machine. This base later brings out the best of cold-weather outer layers to keep you comfortable when temperatures venture south. " 

FABRIC & CONSTRUCTION: This base layer uses a Merino wool/polyester blend for increased durability and to enhance the natural wicking natural of the fabric, thereby reducing overall dry times. The resulting garment offers an increased performance capability under exertion while remaining characteristically soft against the skin. It also means this garment can be machine washed.

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.

Good quality product

I like the quality and performance is good, had to buy a size larger as they seem to run pretty tight. Returning item for different size was very easy, Pactimo’s customer service is quick to respond via email, but could never get anyone to answer the phone when I had a question. But it is all good

Is this possible?

Great! Base layer that is super lightweight and keeps me ridiculously warm. Perfect compliment to the early morning sub-40 degree ride with a long-sleeve Pactimo jersey.

Go to garment for most occasions

During the winter in Southern California I wear the the merino wool base layer on and off the bike. It’s comfortable and warm, but not too warm. My closet is full of these Pactimo base layers.

High grade wool base layer

As a San Diego rider with no winter riding kit to speak of I recently turned to Pactimo to solve that problem. Last week, with rain threatening and a start in the 40s, with the mid 50s expected, I headed out on a 160 miler with my new threads. I had the wool base layer under my new Storm+ long sleeve jersey and that is where I think I made my mistake. Both garments are so warm that I quickly sweated out. Happily, even though the wool was damp all day, I never got cold over the entire 10 hours. Nice. I think if I had been wearing a short sleeve jersey that could let some moisture escape I would have dried out and been fine. I think for a true cold weather ride this piece would be a must. I will be judicious as to when I use it in the future as it works to well! The fit and finish are near perfect.

Base Layer par excellence

Wow! Just when i needed to upgrade to a fine base layer these came on sale and had my size available. For me, a base layer is essential to contain perspiration and give support where its needed. It is comfortable, sized perfectly for my build and has kept me warm during cooler rides. It was a great idea to purchase two.

High Grade Wool Base Layer - Men's.

I'm 6' 170 Lbs I purchased a large size in the High Grade Wool Base Layer - Men's. It fits a little snug but is very comfortable while riding an under another layer or two. It whisks away perspiration well and remains dry or the exterior. I have this in long and short sleeves and they both help to keep me warm on long winter rides.

About as perfect as you can expect

This purchase started out with me ordering based on the size chart (Large); received promptly (shipping from Pactimo is first-rate), but the Large was simply not large enough for my taste. It could work, but I wanted a little more room. Returned (at no cost), and received the replacement (XL) roughly a week later; again, their returns/refunds/shipping are all TOP NOTCH! On to the garment: I like the fit of the XL and the feel of the wool/poly blend material, and after wearing it for the first time today on a crisp late winter/early spring morning ride (OK, it's SoCal, it's not really cold) I am sold. The fact I got this thing for a steal on sale is icing on the cake! Definitely would recommend to others and would buy again.

Nice and warm

Was worried about the length, but it fit just fine. Definitely snug, like a baselayer.

well fitting base layer

I am 6 feet and 185. The XL fits well. Except the sleeves are slightly tight. In practice this has not bothered me. But, I do tug on the sleeves to try and stretch them out a little when I first put them on.

Excellent base layer for chilly rides

Quality is excellent. Fit runs a bit small -- I ordered 3XL and the fit is snug. I usually order 2XL. Definitely recommend this item.

Wool base layer

The base layer is very warm and remains warm even when sweaty.

My second one

Enjoyed my first one so much that I needed another. I use this a lot during the fall and spring, so it's helpful to have two on hand. The fit is great and they stay warm when wet. Great short-sleeved base layer.

Richard P.

Fit was very tight, but acceptable for a base layer. Great feel of the fabric and kept my core warm but not hot, perfect. Excellent overall product.

James K.

These base layers are part of my regular Fall and winter gear. I have both long and short sleeves. I’ve been known to wear them under street clothes too.
