Glad to read you found a way to replace that perfect tool! I hope you got the larger FL eyepiece covers from Zeiss in the meantime. And if you want an even more compact set, that 8x30 SFL does not really need a full-size Zeiss strap. Though my wife is still very happy with it.Happy end (except for my wallet): I bought another 8x30. Weather is terrible, so no real outside use yet, but peaking out of the window, the new one is just as fine as my memories of the lost one.
As for myself, I replaced it with a more compact strap model made by Op/Tech USA. The "BIN/OP STRAP - QD" comes with two "Mini QD Loop Connectors" that have so far proven very sturdy. B&H in the US sold the strap for $12.29. I ordered two, and with shipping to Switzerland ($13.95) the total was $38.53. The added convenience makes this a great buy in my opinion. And I still have a spare for my wife in case she changes her mind in the future.
