Quality sleep is what separates a good Great Walk from a great one. Our members have tested sleeping bags and mats across New Zealand's nine Great Walks — here's what actually works in huts, on platforms, and under the stars.
Our Members' Top Picks
Sleeping Bags for Great Walk Conditions
For most Great Walks during the main season (October–April), a bag with a comfort rating between 0°C and 5°C is sufficient for hut stays. Campsites and shoulder-season tramps demand something warmer. Choose down for weight savings; synthetic if you expect wet conditions.
Down Sleeping Bags
The go-to choice for weight-conscious Great Walk trampers. Down packs smaller and weighs less than synthetic for equivalent warmth. Treated down (hydrophobic) handles NZ's humidity far better than untreated. Our members rate the Sea to Summit Spark and Western Mountaineering UltraLite as standouts.

Synthetic insulation retains warmth even when damp — a real advantage on wet NZ trails. More affordable than down and easier to care for. The Therm-a-Rest Questar and Mountain Hardwear Bishop Pass are solid choices for trampers on a budget or expecting rain.
View on AmazonTemperature Ratings Explained
- Comfort rating: The temperature at which a cold sleeper will be comfortable — use this as your reference.
- Limit rating: A warm sleeper's minimum — not a safe guide for most people.
- Extreme rating: Survival only. Ignore for Great Walk planning.
- NZ rule of thumb: A 0°C–5°C comfort bag covers most Great Walks Oct–April. Go lower for Routeburn or Kepler in shoulder season.
Sleeping Mats: R-Value and Ground Conditions
Even in Great Walk huts, a sleeping mat makes a significant difference — the bunk platforms are hard and cold. R-value measures insulation from the ground; higher is warmer. For NZ Great Walks, an R-value of 2.0–4.0 covers most conditions.
| Condition | R-Value | Typical Use |
|---|---|---|
| Summer hut stays | 1.0 – 2.0 | Abel Tasman, Heaphy (summer) |
| 3-season huts & campsites | 2.0 – 4.0 | Milford, Kepler, Routeburn |
| Cold-weather campsites | 4.0+ | Shoulder season alpine tracks |
Closed-Cell Foam Mats
The Therm-a-Rest Z Lite Sol is the benchmark — virtually indestructible, lightweight, and functional even if punctured. The trade-off is bulk; it won't compress for packing. Many members carry foam as a backup under an air mat for extra warmth.
View on AmazonSelf-Inflating Mats
Open the valve and they inflate themselves (with a few extra puffs). The Therm-a-Rest ProLite and Sea to Summit Camp Mat S.I. offer a solid balance of comfort, insulation, and packability. A reliable mid-range option for most Great Walks.
View on AmazonAir Mats
The most comfortable and packable option — and the most popular among experienced Great Walk trampers. The Therm-a-Rest NeoAir XLite and Exped SynMat HL are community favourites. Pack down to the size of a water bottle and deliver excellent R-values for their weight.
View on AmazonSleeping Bag Liners
A liner adds 3°C–8°C of warmth and keeps your bag clean across multiple hut nights. Silk liners are lightest; fleece liners add the most warmth. A practical addition for shoulder-season trips or trampers who run cold.
View on AmazonWhat Our Members Never Forget
- Store loose, not compressed: Always store your sleeping bag in a large cotton sack between trips — never in its stuff sack long-term.
- Air it out after every night: Moisture from your body reduces loft and warmth. Hang your bag each morning if possible.
- Protect your mat: Carry a small repair kit — a punctured air mat mid-trip is a miserable experience.
- Layer your sleep system: Wearing a merino base layer and socks to bed adds meaningful warmth without extra pack weight.
- Check hut mattress quality: Great Walk hut mattresses vary — some are thick foam, others are thin. A good mat ensures consistent sleep regardless.
