    Tim,

    Interesting post! I have been a convert to merino after wearing my helly’s for everything I’ve done since Norway to about 3 months ago. They did loose the elastic in Norway but I blame that on the sea salt more than the tops themselves. But got the everyday ice breakers to try and save money and they loose their shape massively between washes – was given a 260 top by my old work as uniform – and wore it nearly everyday the air con was cold! and it never lost its shape was lovely! Ice breaker say this is due to the stitching they have changed it since bringing out red ram and now everyday in their 150,200, and 260 weights stuff, so was just wondering what ice breaker it was you had. As thinking about getting another proper one – had to return my uniform when I left :(

    Hi Lizzy, my Icebreaker’s a bit warn now so I can’t read the label properly. It’s Icebreaker 200 and looks, from their website, just like a Mondo Long Sleeve Half Zip.

    It’s less that it’s lost its shape over time though and more than it’s just not as stretchy, close fitting and figure hugging as my bamboo top or Helly (and I think that’s the material rather than the cut).

    Hi Tim,

    In reference to your comments on bamboo vs. Merino:

    Could you please advise if this also applies to ‘socks’ as well as tops??

    I’m wanting to find socks that not only pull moisture away from the skin, but also keep your feet cooler when enclosed in footwear. I.e. Leather shoes, boots etc.

    Thanks kindly,

    Dean, NZ.

      Hi Dean,

      Good question. I’ve used a few different types of bamboo socks now, they’re pretty common even in menswear departments these days, but they really vary from brand to brand.

      I reckon they’d definitely be worth a try. They’ll almost certainly be tougher and cheaper than merino. My Bridgedale bamboo hiking socks have been good, for example, but, for what you’re describing, I’d probably not recommend BAM’s bamboo socks. Sticking with regular looking hiking socks that just happen to include some bamboo is probably your best bet.

      Do let me know how you get on or fire away with any more specifics.

      Tim.

    Hi Tim,
    Very interesting blog, I work for a clothing/underwear company that sells bamboo, silk and cashmere products. I have tried out our bamboo thermals when I go into the mountains to snowboard and walk. I find them excellent, they seem to regulate your temperature and like you say they feel much softer and more comfortable. If its ok by you I would like to use your article on our facebook page ? We are called silkyboo and you can find us at http://www.silkyboo.com
    thank you

    Hi Tim,
    I have read your article on the comparison of different materials as well as this article.
    They are both comprehensive and good, however, you did not mention anything about the warmth and this could be an important factor as well.
    The bamboo material sounds interesting and I recently saw the Trekmates bamboo baselayer at my local store. It isn’t expensive and your review makes me interested to get one.
    Could you let me know if bamboo has high warmth and how does it compare to merino?
    I see everyone in cold weather expeditions wearing merino wool so I am under the impression that it offers the most warmth and is the baselayer of choice in cold climates.

    On another note, if I were to layer 2 merino wool base layers – an Icebreaker 200 under a 260, would that be too much? Would my skin be unable to breathe if I used 2 merino wool base layers concurrent or any 2 base layers at all?
    I’m planning to go to an extreme cold place

      Hi Pamela,

      I didn’t comment on the warmth for two main reasons:
      1. As you hinted at, you can just wear more than one if you want to be warmer
      2. The bamboo and merino ones do indeed tend to be warmer but they are much worse at getting rid of sweat so if you’re working hard then they’ll make you colder

      In short, if you’re working hard and sweating then synthetic will usually keep you warmer. If you’re working less hard, tend to run cold and/or will be in cooler conditions, bamboo and merino will be warmer. For extreme cold, merino tends to be most popular.

      In answer to your second question, wearing two merino wool base layers would be absolutely fine. No different from putting a fleece over the top or, in every day life, wearing a t-shirt and jumper/pullover. You could wear five base layers if you really wanted and breathability would be fine.

      I hope that helps but feel free to ask any more questions.

      Thanks,
      Tim.

      P.S. Where did you see the TrekMates tops? They’re my favourites but I’ve never found them again!

        The Trekmates bamboo is found at a shop in Singapore called Adventure21.
        As far as I know, they are the only shop in Singapore that carry Trekmates products and they have quite a range of Trekmates stuff.
