Reviewers overwhelmingly had a great experience with this company. Many customers frequently share that the base layers are exceptionally warm, well made, and keep them comfortable during cold weather activities. Consumers also love the overall quality of the items, noting that everything performs wonderfully just as advertised. People often mention the easy ordering process and the surprisingly fast delivery times that exceed original expectations.

I just had to share my amazing experience with the heatrub top I bought at the Sportsmen show in Puyallup!
When I returned to Juneau, AK, we faced some pretty intense cold spells—perfect conditions to put it to the test. I wore a bra, an icebreaker tank top, the zerofit heatrub top, and my Arc'teryx atom hoodie jacket on top. I had two fleece leggings and alpaca socks on.
My fiancé and I went cross-country skiing for about an hour on a frozen lake by the Glacier with temperatures around 10 degrees. To my amazement, the heatrub kept me incredibly warm! Typically, I'd need multiple layers for that level of warmth.
I'm so impressed that I ordered the leggings, socks, and another color top to try out. I can't wait to see how they perform!
Thanks for creating such a fantastic product!

Greta review Marie, please spread the word up there in Alaska.. Love it
Product arrived sooner than expected. It was neatly packaged and in good condition upon arrival. Wore the Ultimate Base Layer top for the 1st time a few weeks ago. It lived up to the claims!
Liked it so much that I purchased another Ultimate Base Layer top, a pair of Ultimate Leggings and a Heat Move top. Heading to Alaska in late August this year. These are on the pack list!
Absolutely wonderful experience. I am looking forward to getting more of the zerofit products. Super happy with the presentation and information that was given to me when trying to buy what I needed. Wonderful products

Love it Shyne, I am glad we could help you out. Stay warm
Love my new zerofit shirt. Used it on a 18 deg day with only one other thin layer and a coat on top. Kept me warm all day. I can't wait to try out the socks I ordered.

Great news Dan, stay warm and thanks for your time
The ‘Thermal Sox’ are extremely comfortable, stay warm and cushy.
It’s like a magic carpet ride, really.
I’m very hard to get a great review out of so take this as a real compliment!
Wonderful product from Japan.

Thanks Jim, love to hear that... Keep those feet warm
The gear kept me warm and dry on a cold rainy day. The gear is thin and not bulky, easy to move around in while fishing all day, with almost freezing conditions. Yes I am glad I purchased the shirt, the hoodie, socks and neck warmer/gador.

Great review Mark, thanks for your time and I hope you caught some big ones.. Stay warm
The Zerofit Thermal Top and Leggings are an absolute game-changer for cold-weather fishing in the Pacific Northwest! The warmth they provide is incredible, keeping me comfortable even on those freezing early mornings by the water. Unlike other thermals I’ve tried, these don’t just trap heat—they actively generate warmth while remaining lightweight and breathable.
Even in damp, misty conditions, they wick away moisture and keep me dry, which is crucial when spending long hours outdoors. The flexibility and snug fit allow for unrestricted movement, whether I’m casting, reeling, or setting up gear.
If you fish in cold, wet conditions, this is the best thermal gear you can get. Highly recommended for any serious angler in the PNW! 🎣🔥

Fantastic Review Adam, now this is what I am talking about.. good luck fishing
Items arrived in good time. Tried on in cold weather here in CO. AMAZING! Purchased because I’m in my mid 70’s and keep my house temp usually at 40-50 degrees in winter. At my age, my body doesn’t always warm up as fast as it used to! The base layer top I ordered was comfortably warm ( and almost too hot if I was moving about!!). As I age,I think this top will be very useful in keeping my heating bill down!!

Love to hear this JD, saving money and staying warm... Great news
After wearing my Move Zero fit for a second time I find this set to be a very great value. I could not ask for any better customer service, from my first call for fitting questions- which were spot on to having a replacement piece sent. The warmth of the products is as advertised. Definitely would recommend this product.

Thanks beverly for the fantastic review, we always love happy customers... Stay Warm and be safe..
Quick shipping, well packaged and labeled. Tracking info spot on.
Socks are excellent for keeping warm feet in Chicago winters working outside and riding motorcycle !!!
Thank You ….
Clothing is well made and top, socks, and neck warmer fit well. I ordered the bottom one size bigger but it still is a bit small. I am hoping that it will stretch with use.
