A Snowman Trek packing list centres on a four-season sleeping bag rated to −15°C, a full layering system for camps that drop below −10°C, and a 35–37 L daypack, since pack ponies haul the rest across the 316-km route. Sun, altitude and 25-plus days off-grid drive every choice.
The Snowman Trek is a near-month-long expedition through Bhutan's Lunana district, crossing eleven passes above 4,500 m. Operators supply pack animals, so you walk with a light daypack, but the kit you cannot resupply for 25–30 days has to be right the first time. This list covers what to carry on your back, what goes on the ponies, and the items that quietly decide whether you finish. The full stage data is in our Snowman Trek route guide.
What do you carry versus what the ponies carry?
Your daypack holds water, snacks, the day's layers, sun protection, camera and a first-aid pouch — typically 5–7 kg. Everything else (sleeping bag, spare clothes, toiletries) is loaded onto ponies each morning and reappears at camp. That split makes a structured 35–37 L pack ideal. The Zpacks Arc Scout 37L carries a full day's kit at a low base weight, while the climbing-cut Patagonia Ascensionist 35L handles scrambly pass approaches well. If your itinerary has any self-supported sections, size up to a Hyperlite 3400 Windrider.
What sleep system do you need for −15°C camps?
Camps above 4,800 m routinely fall below −10°C in October, and colder in a cold snap. Carry a sleeping bag rated to at least −15°C comfort, an insulated mat with an R-value of 4.5 or higher (often doubled with a foam pad), and a silk or fleece liner for extra warmth and hygiene over four weeks. A warm hat and dedicated dry sleep socks turn a marginal night into a good one.
How should you layer for the Snowman Trek?
- Base: two merino tops (150–200 gsm) and one bottom — alternate to manage sweat and odour over weeks.
- Mid: a 100-weight fleece plus a lightweight down or synthetic puffy (about 200–300 g of fill).
- Shell: a waterproof hardshell jacket and trousers for snow squalls on the passes.
- Extremities: liner gloves plus insulated gloves, a buff, a warm hat and a sun hat.
Sun is as dangerous as cold at altitude. Glacier-grade sunglasses (category 4), SPF 50 sunscreen and SPF lip balm are non-negotiable above 4,000 m, where UV is roughly 50% stronger than at sea level.
What footwear works on eleven high passes?
Sturdy B1/B2-compatible trekking boots with ankle support handle the rocky, sometimes snowy passes. Pack two or three pairs of quality wool socks, gaiters for snow and scree, and lightweight camp shoes to rest your feet over the long evenings. Trekking poles save your knees on the long descents off Rinchen Zoe La and the other 5,000 m cols.
What is the full Snowman Trek kit table?
| Category | Item | Note |

| Daypack | 35–37 L structured | Carried |
| Insulation | Down puffy + fleece | Split load |
| Shell | Hardshell jacket + pants | Carried |
| Sun | Cat-4 glasses, SPF 50 | Carried |
| Meds | Acetazolamide, blister kit | Carried |
What medical and altitude items are essential?
Carry a personal first-aid kit, a blister kit, broad-spectrum sunscreen, water purification, and altitude medication discussed with your doctor beforehand. The route spends days above 4,500 m with no road access, so prevention beats treatment. The official health and entry requirements for 2026 are listed by the Department of Tourism of Bhutan, and recognised altitude-illness guidance is published by the UIAA. For the broader high-altitude kit logic, see our high-altitude trekking gear guide and the dedicated Best Gear for the Snowman Trek roundup.
Timing your kit to the season matters too — a June attempt needs more waterproofing while October prioritises warmth, as detailed in our Snowman Trek season guide. Hikers cross-training in Nepal often reuse the same list on the Three Passes Trek.
What food and resupply should you plan for?
There is no resupply on the Snowman Trek for the 25-30 days between Paro and Sephu, since the Lunana villages have no shops beyond the occasional basic supply. Licensed operators solve this with a full cook crew and pack ponies that carry food for the entire expedition, so three hot meals a day are provided. Your job is to carry personal snacks and high-calorie trail food: aim for 200-300 g of snacks per day, around 1,500-2,000 extra kcal, to top up an appetite that often fades at altitude.
Pack a mix you will still want to eat in week four: nuts, dried fruit, chocolate, energy bars and electrolyte tablets travel well and counter the appetite loss common above 4,500 m. Hydration matters as much as food, so drink 3-4 litres a day and treat all water, since glacial streams carry sediment and bacteria. A wide-mouth bottle plus a soft flask covers both camp and trail.
Because the route is fully supported, your daypack stays light at 5-7 kg, which is why a ventilated 35-37 L pack works so well. The full carry-versus-pony split is in our Snowman gear guide, and the seasonal food and weather logic in the Snowman season guide. The same calorie planning applies on Nepal's Three Passes Trek.
How do you test and break in your Snowman kit?
A 25-30 day expedition is the worst place to discover that a boot rubs or a pack creates a hotspot. Break in your trekking boots over at least 80-100 km of walking before the trip, ideally on varied terrain with the socks you will actually wear. Load your daypack to the 5-7 kg you expect to carry and walk several full days with it, adjusting the hipbelt and shoulder straps until it sits comfortably for hours.
Test your sleep system at home in cold conditions so you know your bag and mat keep you warm at the temperatures you will meet above 4,800 m. Wear in your waterproofs, check every zip and seam, and confirm your sun protection and gloves fit over each other. Anything that fails on a weekend shakedown hike is far cheaper to replace at home than to suffer for four weeks in Lunana.
Bring a small repair kit too: tenacious tape, spare buckles, cord and a needle and thread cover most field fixes. The full carry-versus-pony breakdown is in our Snowman gear guide, and the seasonal weather context that drives your testing is in the Snowman season guide.
Frequently Asked Questions
Do you carry all your gear on the Snowman Trek?
No. Licensed operators provide pack ponies that carry your sleeping bag, spare clothing and main duffel between camps. You walk with a 35–37 L daypack holding only water, snacks, layers and essentials, usually 5–7 kg.
How warm a sleeping bag do you need?
A four-season bag rated to at least −15°C comfort is standard. Camps above 4,800 m regularly fall below −10°C in October, and an insulated mat with an R-value of 4.5 or higher keeps ground cold from sapping warmth.
What footwear is best for the Snowman Trek?
Sturdy, broken-in trekking boots with good ankle support and a stiff sole handle the rocky and occasionally snowy passes. Add gaiters, two to three pairs of wool socks, and trekking poles for the long descents off the 5,000 m cols.
What sun protection do you need at altitude?
Category-4 glacier sunglasses, SPF 50 sunscreen and SPF lip balm are essential. Above 4,000 m, UV radiation is roughly 50% stronger than at sea level, and snow reflection on the passes intensifies the burn risk.
What weight should your daypack be on the Snowman Trek?
Aim for 5–7 kg in your daypack, since the ponies carry the heavy items. That covers two to three litres of water, snacks, a puffy and shell, sun kit, camera and a small first-aid pouch for the day's walking.
