Frequently Asked Questions
Do I need a dry bag for NZ tramping?
Yes, for anything you can't afford to get wet — sleeping bag, down insulation, electronics, spare clothing. NZ conditions (river crossings, sustained rain, condensation) mean a good pack liner or individual dry bags are standard kit on any serious tramp. Sea to Summit lightweight dry bags are the practical choice for most NZ trampers.
What size dry bag should I get?
1–3L: electronics, documents, small valuables. 8–13L: spare clothing, down jacket. 20–30L: sleeping bag. The Sea to Summit Lightweight 20L handles sleeping bags; the Ultra-Sil range suits ultralight trampers counting grams.
Are Sea to Summit dry bags actually waterproof?
Yes when used correctly — the roll-top closure needs to be folded down at least 3–4 times and buckled. Partially rolled closures will let water in. Used properly, Sea to Summit dry bags are reliably waterproof for river crossings and submersion.
