I have a Hilleberg Nammatj2 tent which comes in handy on ski tours in Norway and Sweden. Problem is with all that snow melting, the inner and outer door zips get iced up and pretty much stuck and I just know I’m going to end up pulling out a zip coil and wrecking the tent mid way through a trip.
Ive thought about getting the door panel adapted and adding a snow tunnel secured with cord ( basically a short tube of material I can clamber through, like you see on heavy duty pyramid tents at the Poles) to act as an alternative door or finding some way of ice-proofing the zips (Vaseline, light oil?). This must be an issue on big mountains, anyone got any handy hints, experience/opinions on snow tunnel doors or an alternative solution? Thanks.
