Design: bivy sack
Price Paid: £190
This is without doubt the best gore-tex bivi out there. Its unusual length, 250cm, allows gear to be stored inside. This acts to raise the gore-tex fabric from your face when fully zipped in. The mouth can be held up using its external loops, making for a roomy bug bivi, with its integrated mosi netting.
It's made by a British company called Mountain Range.
