  • 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 Made from Polartec® Alpha® Direct — the same insulation that was originally made for the U.S. Special Forces when they needed an advanced insulating fabric in their combat uniforms — the Nitro offers pared back performance.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.

Is it true to size - as a base or mid layer? - thanks
Molly on Jul 7, 2021
BEST ANSWER: It's definitely on the snug side Molly --- I bought a Medium and it's ok with a merino base layer underneath, but doesn't fit like a "normal " Med 100wt fleece --- great piece of gear that does everything it says on the tin :) ... cheers, Derek

Has anyone experience using this layer in the sun or above 20C? Just wondering about sun protection and ventilation.
Shawn J on Jul 12, 2021
BEST ANSWER: The Macpac Nitro has become one of my favorite gear for outdoor activities. It keeps you warm and still have a good ventilation while hiking. If it’s getting cooler I just add my wind-jacket. I use the Nitro all the time but think you would probably think it’s a little to warm to use in the sun when it’s above 20C and you are on the move. For sun protection I would recommend a sun shirt. I hope Macpac never stops selling the Nitro, cause it’s just so well functional in the outdoors.

can you detach the hood?
SamSam on Jul 14, 2019
BEST ANSWER: No the hood is part of the garment however it is ver small and light weight and looks like a collar rather than a typical hood
I'd like to order one, but the color & size options are extremely limited right now. Are you going to make another run of this garment? It looks like it was very popular, and I'd love to get one.

if I order online and it doesn't fit well, is it returnable to a local store rather than posting it back?
daniel on Mar 24, 2021

Yes, if you pay with Credit/Debit card then you can return into a store, as long as it is resalable and with tags.

Is there a shipping option to the US?
Caboose on Dec 20, 2019
Thank you for getting in touch with us.
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
Is there shipping to Canada? I live in the US but I know someone in Canada who can resend it to me
