The OneTen Intimo Seamless long sleeve base layer is a really stretchy, fast drying base layer that provides sufficient warmth to be useful right through the winter.
The Intimo is mostly polypropylene with enough elastane in there to provide loads of stretch. It's cut long in the body and sleeves so there's no danger of any exposed skin when you're on the bike and you get quite a high neck to keep the cold air out.
Oneten have designed the Intimo with the arm and neck holes positioned to reflect your riding position. The neck hole is a little more forward than normal, for example. I wouldn't say it makes a massive amount of difference on something as stretchy as this, but it all helps. The fact that the body-mapped fabric is so stretchy and springy certainly means that the Intimo sits right next to your body without discomfort, and flat seams throughout are a definite bonus. Plus, there are no manufacturing/wash labels inside – all that info is stitched onto the hem.
The Intimo is a mid-weight as base layers go, providing considerable warmth for the cold weather. I've been using it when the temperature has been below about 10°C, although it'll largely come down to what you wear over the top.
The best bit, though, is that it deals with moisture really well. You can get anything damp if you really jack up the intensity, but this base dries very quickly so if you get it damp on the way up a big hill, it'll usually be pretty dry before you get down the other side - so you don't end up cold.
How does it get on with the old sniff test? Well, you wouldn't want to keep the Intimo on for long after you've finished riding but it's by no means a particularly serious offender on the odour front. A silver ion treatment keeps things down to a reasonable level and it smells fine after a wash.
Stretchy, fast drying base layer with enough warmth to see you through winter.
road.cc test report
Make and model: OneTen Intimo Seamless long sleeve base layer
Size tested: M/L
OneTen say, "For ultimate warmth in cold riding conditions, the Intimo Seamless Mid Neck Long Sleeve Base Layer is the foundation of your winter riding wardrobe.
"Sharing the same fast-drying qualities of all Intimo base layers and still in a light, comfortable and great-fitting package, the Intimo Seamless Mid Neck ups the ante for harsher conditions with extra insulation properties and high-collar neck protection made of soft, comfortable fabric.
"The fabric features an innovative 3D-structured knit that traps a layer of warm, dry air next to the skin, keeping your core temperature cosy when the mercury drops. It works equally as hard when the heat is on, with rapid moisture wicking to draw sweat away from the body.
"One-piece seamless knitted sleeves feature the same innovative 3D ribbing while elastene stretch yarns give a fantastic on-bike fit and feel soft and comfortable to the touch, enhancing the 'second skin' feel of the Intimo Seamless Mid Neck."
