Why we made this
A versatile mid layer for days in the mountains — whether it be climbing or other activities, this super light active insulation will keep you warm no matter what.
  • Product Description
    A versatile mid layer for days in the mountains, whether it be climbing or other activities, this light active insulation will help to keep you warm. Made from Polartec® Alpha® Direct — the same insulation that was originally made for the U.S. Special Forces when they needed an advanced insulating fabric in their combat uniforms — the Nitro offers pared back performance. An evolution of fibre, Alpha® Direct eliminates the needs for a backing fabric and can be in direct contact with skin or other fabric layers, increasing breathability and reducing garment weight. Designed with alpinists and multi-sport athletes in mind, this minimalistic mid layer is warm and incredibly breathable.

Totally happy!
Really great Pullover. I‘m completely satisfied about the material. Size is fine as Slim fit. If you like more a loosely style, take one size bigger. Transport to Germany was also great and quick.

Great Workmanship and Warmth!
The pullover arrived quickly to my home in Canada via DHL and is exactly as pictured. I appreciate the quality stitching and fabrics. I am very impressed with its warmth, especially given that it weighs almost nothing! I will definitely recommend to others!

Recommended but go Larger
Very, very warm! Good dispatch and service from Macpac. Bought medium (6ft, 94kgs and 42 chest) and it’s a small fit only good for first layer against the skin. If you want to put this over your basic layers buy a larger size. This will work as a replacement for a puffy for long distance, ultra light thru hikers, just put your rain jacket over the top and drop the puffy. Hard to do but will work and will drop your weight. Excellent product but go larger on size.

I haven't managed to rip it yet. The alpha fabric is still quite lofty but it has noticeably got thinner like with all fleeces over time (Like a person going bold).

I have worn it over 200 times now since I bought it last Christmas for work and hiking. I have probably washed it about 20 times.

I have attached a close up picture of the fabric after 200+ washes.

Overall I really like the Nitro. Its hard to beat its warmth to weight ratio. My Nitro is 125grams (4.4oz) with out the pocket and with a Melly hood mod. Honestly I couldn't put number on how much warmth it has lost over time. It still feels the same as when I bought it. It must have lost some warmth though.

This is the ultimate fleece for ultralight backpacking. I would love it if the next iteration of this product could have the pocket removed and for the hood to be cinch able like in the linked the video. Also more colours would be nice.

Warm and light
I was a bit skeptical about how warm such a light garment could be but was pleasantly surprised at the instant warmth when I tried it on. Like others have said though, ditch the pocket on the men's version - it's not needed. I even tried the women's one that doesn't have the pocket but the largest size was still too small. Tempted to buy another and use them together with a lightweight down jacket for colder conditions

Ultralight midlayer
I was skeptical at first at this fluff-ball midlayer but now am a convert. Because it is just pure fleece with zero frills it is an unbelievably light midlayer. Because it is a delicate outer it is best used in your winter clothing system with an outer softshell or hardshell jacket for protection. I'm often doing climbs where ditching the midlayer is the first option to save weight, but you often regret later. With the nitro pullover you hardly notice the weight but it adds decent amount of extra warmth.

Fantastic top
I love this thing! So warm and airy. I really wish Macpac would ditch the chest pocket though. I would have given it a five out of five but that unnecessary chest pocket....

Macpac, please, please make some pants out of this stuff!

Good fabric performance, would prefer zip and no pocket for optimum usage.
Bought this as I wanted a no frills alpha layer.
It's pretty good stuff. I love it's lightness, fast drying warmth.

The Nitro sizing is a bit tight. I'm Normally a Large, so I ordered large. but this fits more like a medium - or a tight base layer, but less stretchy.
Wish I'd ordered XL now . Used on a 19 day trip recently, and performance is top.
Wish it had a simple neck zip, and no pocket (like the ladies version).

Can you ship to USA?
calhan on Dec 17, 2019
Unfortunately Macpac isn’t currently shipping to USA. We hope to get this rectified in the near future.
In the meantime, the only way would be to get it shipped to a friend or family member that lives outside of the USA, and they could then re-send onto you.

Kind regards,
The Macpac Team
Has anyone else purchased one of these? I have, excessive fluff and pulling. To the point where covered in it. I've washed it too, still fluff!!!

BEST ANSWER: Hi, I washed it once and the fibre loss decreased a bit. Maybe you washed it a couple more times since spring and the self-dismantling stopped?
