I did order a bright orange hotpack in the end. The ultralight seems to come in see through silver-ish only, and the extra 20g don't worry me all that much.
Also, I am quite happy with all my other sportful stuff, so happy to just give it a try at about AUD100 less than the rapha brevet jacket.
Didn’t realise the regular one was only 20g more! Ive got the ultralight but it’s a medium and I need a small really. I’ve always been very impressed with sportful in general, so I might have to look for a regular one in small.
Sportful hotpack ultralight, 50g, smaller than a tennis ball when compressed.
