Delivered very promptly - thanks
@GJT!
The gilet is just right for me. It is quite a snug fit at the moment but I am a few pounds over the weight that I want to be. It should be a perfect fit once I have shed that blubber, but will still be usable in the mean time.
If anybody else is thinking of buying one of these
Altura gilets - they are nicely made. The L size would be a perfect fit for someone about 6 feet tall and with a 34 inch waist, but would probably be fine for those 5' 10" - 6' 2" tall and with a waist size in the range 32"- 36" and a normal chest measurement for someone of that build. (Bodybuilders need not apply!) Ideal for cool weather rather than freezing conditions.
PS I have now done a few rides wearing the gilet in chilly windy conditions and it has been very good. It neatly plugs the gap between milder conditions suitable for my lightweight gilet, and severe conditions when I will be wearing my heavy-duty jacket.
