One word... Icebreaker. One place.. Trims.. or Mountain Designs or their own shop on Rundle St.
Do not pass go, do not collect $200, go directly out and buy an Icebreaker Bodyfit 200 baselayer. They are awesome. I think I worked out I've had mine for about 6 years and I wear it all the time during autumn to spring. It basically helps regulate body temperature so even if it's warm it's still good. It wicks sweat from your body and, as you know being merino, it doesn't need to be washed after every ride.
Last year I got a sample of one of Icebreaker's jersey/ adventure wear and it is the same weight but with a zip. I also wear it as a baselayer. I've also got a heavier long sleeve t-shirt that is not meant to be a baselayer as such but it's great too.
It's from sheep, it's merino and there is only one Icebreaker! Get some socks while you're at it!
Did I mention Icebreaker?
I bought a Merino LS base layer from Mountain Designs ( their "home brand" as the prices for the rest were really stupid but had pretty patterns on them!). A guy that works there is a cyclist and recommended going no "warmer" than their lightest range (which from memory was 175 or 200??). He was spot on for me, but I run hot within minutes of any exercise. His advice was to avoid synthetics like the plague as they are a nightmare with sweat - tick. Merino breathes and wicks well. Doesn't stink at the end of the day either!
Annapurna didn't have any short sleeve baselayers when I was in there recently. Bought Mens 200 Lightweight Sprint Tanks instead. Very comfortable under a short sleeve jersey.
ditto on the Merino..
I bought mine from Ground Effects and it works a treat. Made in New Zealand and to a really high standard. I'm expecting mine to last years and so far after a season they still look brand new. I sweat big time in summer and the vest keeps me super warm and wicks away the sweat. Riding in temps down to 5C I only need Merino Vest (suggest getting t shirt perhaps to stop drafts between arm warmer) Jersey, arm warmers and a windbreaker and all is sweet. I hate the cold too!! I also wear Merino longs which again I don't get all hot and sweaty in or get too hot in...they'll do me from any temp I've faced so far up to around 20C without me feeling too hot. I pretty much wear them for commuting once it gets below 13C or so. I can't recommend this stuff enough.. pricey but well worth it. I've done the cheap leg warmers that stretch and fall down all the time and won't ever go back to that.
So ground effects or ice breakers...either way Merino all the way. Also if you get referred to Ground Effects from a current member you'll get a $30 voucher off your first purchase!!!!
I'm happy to refer you if you choose ground effects and don't already know a current member.
I hear Icebreaker may be worth a look.
Do they have pretty patterns? I hear florals are in :)
So they wick the sweat away & you dont wash them after a ride? Where does the smell & salt go?
Do sheep smell?
Yes. Badly. Take it from someone who had to walk behind them for miles when I was a kid!
Little Bo Peep?
Well they help me regulate my body temp so I don't overheat in the first place. I don't think I actually sweat much at all when I wear them...although I notice sweat where they tuck into my nicks. My top is sleeveless so this helps to reduce any odour build up. I wash them with my merino longs every week or two on the woolen setting so I don't stretch/damage them.
