Hand-Warming Mitts

Enjoy convenience at your fingertips to provide extra warmth whenever you need it. The innovative, built-in mitts are easy to roll over your hands in cold weather and simply roll off once you've warmed up.

Dynamic Heat Control

The lightweight, breathable fabric helps optimise your body temperature in any conditions. Carefully positioned micro-perforations improve airflow to your body, so you can run warm without worrying about overheating.

Flexible Fit

Experience ultimate comfort whilst you run thanks to the super-soft, stretchy fabric that doesn't compress to your body like the common base layer. This slightly looser fit, combined with the a longer body, means you have the flexibility of wearing it on its own or under another top.

Seamless Design

The base layer is designed using 360° seamless technology, meaning there are no side seams or labels - reducing the risk of rubbing or irritation. It also means a significant reduction in wastage during the production process vs the traditional cut and sew method.

Moisture-Wicking

The technical fabric blend has unrivalled moisture-wicking properties. This means that base layer removes sweat from your skin quickly, keeping you dry and comfortable, mile after mile.

Fab Top!

Got this at half price in the sale. Can be used as a baselayer or on it’s own. My only quibble is that it could be a bit longer in the body.

Trying to be two tops at once and failing

I'm rather disappointed with this base layer. I've got many other products from Runderwear, like pants, shorts and socks so known from experience they are usually great quality, and I was looking forward to having a base layer made from their high tech seamless material.

However, the fit is all wrong and is not comfortable to wear as a base-layer. It'll probably be ok as a warmer weather long-sleeved top for late Spring, because to me it acts more like an outer-layer than a base layer. But even whilst I was wearing it as a single layer, the shape is strange and gives me a kind of muffin-top look around the waist.

As someone on the upper end of the medium size, even I find the medium sized top way too loose. I bought this specifically to be a base layer under my main outer layer, yet it doesn't sit well under the outer-layer. I have had plenty of base layers over the years and they are more fitted, without being tight and restrictive.

Whilst the mittens look like a handy bonus feature, if you're not using them then you're left with excessively long sleeves, which when scrunched up causes let more conflict with the outer-layer. They shouldn't even be on this top - that's the kind of thing an outer-layer takes care of, or just use gloves.

It's an ill thought out top and I'm rather annoyed given the price. It's not a proper base-layer - it's just a baggy, thin long-sleeved running top.

I'll give them credit for good body length and the material.

Hey Andy,

Thank you for your review, I am sorry to hear that you are not getting along with the Base Layer. This has been a favourite for many so I am sorry to hear that you are not loving it. It does sound like you are not in the perfect fit, We recommend in following the size guide and the Base Layer should feel snug dependant on what size you go for. Some prefer the looser fit so size up but some like the fitted look and stick to the size we recommend. If you have any queries or you are unsure on sizing please do not hesitate to get in touch. Always happy to help!

Love the mitts, sleeves too long

I have now bought a medium and a large of this base layer. The material is soft, it seems to wick well, it keeps me warm, but I don't overheat. And I love the mitts! However, there is one issue (and it may be my body shape!). The medium is a bit snug, but the sleeves are perfect, the large fits well, but the sleeves are too long. I think you need to have two sleeve lengths for the base layer - one for the tall, slim athletic type we aspire to be (with long arms), the other for the middle-aged, shorter, slightly overweight man I appear to be (with shorter arms), but who still needs a large for comfort.

Thank you for your feedback this is greatly appreciated and will be passed onto the team. The base layer is favourite for many and I am sure you can understand why, We hope you have many happy miles wearing your Runderwear Base Layer.
