i called in to the show room of planet x today the web-sight is showing some stock levels wrongly, so worth dropping them a email or a phone call to see if the top or baselayer you want is in stock.
having said that i know the short sleaved black 120g baselayer is out of stock but is on order.
the on - one ss top is exelent for recumbent riders as it has no pockets or butflap can also be used as a baselayer under one of the thicker long sleeved tops in the cold at £19.99.
also £19.99 long sleved half zipp black 190g baselayers are in stock but do not appear on the web-sight ?
i got the last green On-One 100 percent Merino Wool LS top in large in stock at £19.99
, when they get them back in i think all the rest are now £27.49
also good for recumbent rides they have three back pockets but with buttons not zip's and again have the squared of bottom.
