Got a big road ride coming, can’t stand having heavy stuff pulling my jersey down for ten hours. Anyhoo- I could leave it but I want to take photos, so just wondering what will fit an iPhone 8plus.
Topeak fuel tank large is the only thing I’ve seen, but not in the flesh.
alpkit?
Some reviews say it’s a bit floppy. Anyone got the Alpkit one?
I bought this off Amazon recently for my fat bike. It's rad, and only £13

The phone bit is pretty big and it has ports for charging.
My phone is a moto g5 and it fits with a fair bit of room to spare.

MissGrape Node?
I have just got the enduro bundle from alpkit. Enduro pod looks good but unfortunately is too small to fit my phone, wallet and keys, however iPhone alone fits easy.
The Passport one fits my Huawei Mate 10 Pro (6" screen) and the touchscreen works through the plastic window.
