We Say – The long sleeve top and the long pants are sold separately, and listed under the ‘Warm Originals’ title (if you’re looking online, or in the shops, this is the range of Odlo clothes than they’re part of).

They’re set I’ve got are listed as Sapphire Blue, it’s like the blue of the pants, above, rather than the darker blue of the top. It’s bright but nothing too loud, and I find it a nice change from black, which is what all my other thermals have been. These Odlo Thermals also come in other colours if blue isn’t your thing; the website shows a choice of grey, white, black, green and red as well as the striped designs that are a brand new addition to the range.

They’re made from 100% Polyester and they felt reassuringly thick (warm and cosy) when I first put them on. I’d been wearing my old merino wool underwear for a few weeks beforehand and these felt similar, although a little more bulky and therefore a touch more comforting as a result.

They’re also warmer than my merino, noticeably so. I wore the top and pant set out at first on a December day under a regular trouser and fleece with a rainjacket over that, and found that it only took me about 15 minutes of walking to get up to a very comfortable temperature. The air temperature was around 5 degrees with a 25mph wind blowing constantly, so it was pretty chilly, but once I got up to that comfy body temperature I never got cold again, even though the walk lasted 5 hours. I had to get used to the heat generated by the underwear by slowing down my pace a bit at first and opening my coat and fleece zips, but from then on I monitored myself closely and was able to use the zips to allow sufficient circulation. My point is, I was never in danger of being cold, and I never felt sweaty, my only issue was regulating the heat that the Odlo underwear helped create so that I didn’t get too hot.

After that I wore them on 3 more consecutive hikes, all about 5 hours long and under similar conditions described above. I didn’t shower at all during this time, just like you wouldn’t if you were on a wilderness hike. The underwear only started to smell on day 4, which suggests to me that it’s a good choice for a multi day hike in cold climates. I wore regular boxer shorts under the long pants, so that helped keep the pants themselves fresh, but the top was always acting as my t-shirt as well as underwear, so this does point to the fact that the material must have wicked away moisture well; if it hadn’t, the sweat would have built up and started to smell way before day 4.

The underwear washes easily – there’s no special care instructions so it can be thrown in with everything else, unlike the merino wool underwear I have – and it dried overnight on the airer when put in front of the radiator. More recently I washed it and then dried it on the line in a few hours – it’s winter though and the sun isn’t too strong so I imagine in summer it’d dry in an hour or so, the same as any other shirt, when hung outside the tent.

It also dries flat, no need to iron. I know that looks aren’t the most important thing to consider when buying outdoors clothing but I do tend to think, how’s this shirt going to look in town if I wear it there? I travel light, you need to when backpacking and wild camping, and so all of my kit has to multi-task if at all possible. The thermal top achieves this; it’s an effective base layer for use whilst hiking, it’s a good thermal to wear around camp and it’s also smart enough to wear in town, if it comes to it.

One time I wore the top on an 8 hour hike. It was a calm winters day, about 7 degrees, and I decided to go without my mid fleece so I only had the top on plus my outer raincoat. My arms felt chilly at first as the sun had only just risen above the trees but I was never really cold and after 20 minutes of walking I was at a good temperature, which I kept for the remainder of the day. I wasn’t walking all that time either, so I can say that it retains heat once you’ve built some up internally. I did about 17 miles in all and I was comfortable throughout, and at the end of it I didn’t smell bad either.

The next day I wore the set out under my running clothes, for a 20km run. The temperature is around 6 degrees and the rain is heavy, with a strong west wind. My route was along the seashore so the wind was coming hard at me for 10km (it was an out and back run). I was never in danger of getting wet from rain as my outer gear is waterproof but I was interested to see how the underwear coped with my sweat; would it wick it away well, or would it accumulate and make me cold? The answer is that I didn’t get cold once, even when I stopped halfway to stretch out for 5 minutes. By the time I got back the underwear was wet, although not dripping, and I could warm down and stretch out without feeling clammy. Also worth mentioning is that I didn’t get any chaffing, the material moved well against my skin and didn’t cause me any problems at all.

Most recently I have been in Toronto, Canada where the temperature is around minus 20. I use these thermals for running wear and also for everyday wear. This mornings temperature was minus 24 and these, combined with my Spiro running kit, kept me warm enough for the hour that I was outside.

So I’d say this has shown me that the underwear is a good bet for multi sport use. I find it most useful for everyday wear now we’re into winter, it’s also great for hiking wear and will suit for multi day adventures as it doesn’t need washing much, and if I need something to wear under my running gear on colder days, it’ll do for that as well.
