Zerofit Heatrub Ultimate Unisex Long Sleeve Base Layer TopOur most popular baselayer across the entire collection, the award winning Zerofit Heatrub Ultimate is a best in class, game changing baselayer that has been independently tested and proven to be five times warmer than leading competitors, and twice as warm as a sweater. Technologically enhanced 'Heat Threads inside the garment are activated through even the slightest of movements, gently brushing against the skin to generate positive warmth instantly

Our most popular baselayer across the entire collection, the award-winning Zerofit Heatrub Ultimate is a best-in-class, game-changing baselayer that has been independently tested and proven to be five times warmer than leading competitors, and twice as warm as a sweater.

Technologically enhanced 'Heat Threads inside the garment are activated through even the slightest of movements, gently brushing against the skin to generate positive warmth instantly and the construction of the Zerofit Heatrub Ultimate means the heat is retained.

Unlike other baselayers, the Ultimate does not work on the basis of 'compression for heat' - so not only does it provide greater warmth, but you also won’t feel restrained by an inability to move freely, making it one of our most comfortable baselayers.

It also features a slightly looser neckline design, which allows some heat to travel out away from the body - during testing and development of the Ultimate, a tighter neckline was found to cause some overheating.

A rigorous product evaluation at the iconic Boken Institute - Japan's leading testing organisation - resulted in a Heat Retention Rating of 0.78; a standard baselayer would have a rating of 0.1-0.14, while a sweater would typically have a rating of around 0.3.

Regardless of whether your passion is fishing, hiking, motorcycling, golf, equine sports, sailing, skiing, gardening or you spend a great deal of your working day outside – the Ultimate has got you covered in temperatures as low as minus 10° Celsius.

And because it's so good at keeping you warm, there's no need to 'layer up' with bulky additional clothing - the Ultimate does the work of multiple layers which also makes it a cost-effective heating solution.

PRODUCT BENEFITS

– Independently tested and proven to be five times warmer than a standard baselayer

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.

Sharp Looking Kids Suit With One Missing Piece
Color: Navy, Size: 7 Years, Color: Navy, Size: 7 Years
I ordered this suit for my 6yo son in a size 7 so he would have a little room to grow and get more wear out of it, and sizing is perfect. He did not need it for any specific occasion, he just wanted a suit because apparently kindergarteners sometimes wake up and decide they are businessmen now. Let me start with the positives because there are a lot of them. This is a very well made suit. The jacket, pants, and dress shirt are all surprisingly nice quality. The fabric does not feel cheap or flimsy at all. The jacket has good structure, the buttons are well attached, the seams are clean, and all the little details like the collar and pockets look great. It honestly looks like a proper little formal suit. The pants are nicely made as well and pair perfectly with the jacket. The white dress shirt underneath is also good quality and completes the whole look. Overall, it is a really sharp outfit and would absolutely work for special occasions like weddings, recitals, formal events, church, or family photos. Now for the reason I am deducting one star. The listing specifically shows and mentions that this set includes a bow tie. That was actually the main reason I chose this particular suit over others. Some options only had a standard tie or no tie at all, but my son specifically wanted a bow tie. Unfortunately, the bow tie was not included with mine. That was definitely disappointing because it was one of the main selling points for me when choosing this set. Now I have to go find a separate bow tie that matches, which I was hoping to avoid. That said, I do want to be clear that this issue does not take away from the actual quality of the suit itself. The suit is genuinely very well made and looks fantastic on him. If your child needs a suit for a wedding, formal event, recital, or something similar, this would absolutely work. My son mostly just wanted a suit because he thinks it is cool, so now he has one and can show up to school looking like the smallest CEO in kindergarten. Overall, this is a very nice quality suit set. I just wish the bow tie that was advertised had actually been included.
