Use my long sleeve most rides in winter and early spring without a base layer works perfectly for me, with my gilet when its cold (made out for the same material and breathes well)
Had it on today was about 12 degrees its just that bit more substantial then a jersey and its just so soft and comfortable.
When the temps are going to stay below 55 F (60 if no sun), long sleeves are great. Iāve got a couple from Perl (likely the same as a previous poster) and one Gore, which is slightly lighter weight. Alone, theyāre good to about 45 F, add a summer jersey underneath, and I get to 40, below 40, add a heavier jacket on top.
But if the temps are going to get warm, warmers are preferred, as they come off.
Just this past weekendā¦ Saturday, pretty consistent low 50F. Then sunday started the ride at 48F but warmed into the 60s. So I went for bibs, knee warmers, thicker summer jersey, arm warmers and a vest. Nice to be able to shed layers as it warms.
All comes down to if I am going to use my layers. āDress in layersā only works if you actually use the layersā¦
I wear long sleeves almost exclusively. In the winter theyāre warmer than a jersey plus warmers and more comfortable. I have several different weights I use depending on temperature and I can still add layers under or over it.
Iāve had melanoma 3 times and countless other pre-cancers removed. So summer is also a long sleeve, light weight jersey. I used to wear sleeves but would pull them down ājust to cool offā but would wait too long the pull them back up. Long sleeves donāt allow me to be dumb.
We have fairly significant temp swings here, so Iāve been known to put arm warmers under a long sleeve jersey to get me through that first hour or so until it gets to 50ish, then just pull the arm warmers off and put them in my pocket.
Long sleeve fan here. But Iāve never had a merino jersey. Iāve avoided them because the merino dress shirts Iāve had end up with too-long sleeves from stretching. How are the jerseys for this?
I can see it for the top, but for legs, I really like having leg warmers. So many times short bibs are fine for going uphill, but with the wind it will be freezing downhill. I have had plenty of rides where I put them on at the top, and take them off again once I am down. If I had long bibs it would have been hell, they also tend to be warmer in general, and the main reason the leg warmers help is wind protection.
Iām a baby when it comes to temperature as in Iām always cold so I get a lot of use out of my long sleeves. I also like to protect my tattoo sleeves from sun and scratches so a long sleeve works there as well.
They are the super thin ones like the Rapha pro team so not particularly warm.
One advantage is when it gets really hot I seem to perform really well, we had some 40+ degrees Celsius (104+ Fahrenheit) and I had a TT, long sleeve skin suit, long over shoes and a visor full aero helmet and I was totally fine and all the fast people suffered so I got my best ever result.
Iām a bit of a penguin, & I err on the side of being a little too cold. Otherwise I sweat profusely & consume ridiculous amounts of water (like 800mL in half an hour on one ride), which could become a problem if thereās too long a ride between water sources. If the temperatureās staying over 10Ā°C Iāll probably pick short sleeves. If itās cloudy & staying under 15Ā°C Iāll probably pick long sleeves. (I add a few Ā°C to both if itās an easy ride.) If neither is the case or if thereās massive climbs & descents Iāll probably pick short sleeves & either a very light wind jacket or UV sleeves just to take the edge off the cold when needed. Long sleeves & a wind jacket is also an option for even cooler. I donāt often encounter sub-zero. Another option I sometimes choose is adding non-insulated long tights over cycle shorts, at about the same temperatures as wearing long sleeves. If the temperature goes over 30Ā°C I start questioning my life choices.
So agree with a lot of the posters up thread, plus:
Long day/harsh sun - Thin base under shirt sleeve works better for me than a summer long sleeve
Add sleeves, knee warmers, wind/water resistant gilet if weather or temp is varying
Switch to thermal longs plus base layer if itās cold the whole ride
Iām just trying to figure out a new minimal road cycling wardrobe, layers will feature a lot but long jerseys wonāt outside winter. I suspect a jacket is more versatile, but never had one.
