Packing for the Annapurna Circuit is uniquely challenging because the route traverses an extraordinary range of climate zones in a single journey. Day 2 is subtropical lowlands at 800m where you'll sweat in a t-shirt. Day 12 is Thorong La Pass at 5,416m where -20°C wind chill is normal before dawn. Getting the gear right for this range — without overpacking — is the core challenge.
This guide focuses on exactly what the circuit's conditions demand, with honest assessments of what you actually need versus what gets left in your bag.

The Circuit Packing Philosophy
The Annapurna Circuit demands a layering system designed to handle a 4,600m altitude range in 15 days. This means:
1. True versatility: Every item must work across multiple climate zones 2. Weight discipline: 15 days is long; every unnecessary kilogram punishes your knees on the descent from Thorong La 3. Pass-day readiness: Your warmest gear must be accessible in your daypack for the pre-dawn Thorong La start, not buried in your porter's bag 4. Rain and wind protection: Both sides of the circuit get wet; waterproofs are non-negotiable
Clothing System
Base Layers
| Item | Specification | Quantity | Notes |
|---|---|---|---|
| Merino wool long-sleeve shirts | 150-200 weight | 2 | Manage odor over 15 days; worth the cost |
| Synthetic quick-dry shirts | Lightweight | 2 | For lower valley heat |
| Long underwear | Lightweight merino or synthetic | 2 | |
| Trekking trousers | Zip-off/convertible | 2 | |
| Lightweight shorts | Optional | 1 | Chame to Manang lower sections |
| Underwear | Quick-dry synthetic | 4-5 | Merino if budget allows |
Insulating Layers
| Item | Specification | Notes |
|---|---|---|
| Fleece jacket | 200-weight at minimum | Core mid-layer; used most days above 2,500m |
| Down jacket | 600-fill+, rated -10°C comfort | The single most critical item for Thorong La |
| Warm trekking trousers | Fleece or softshell | For cold evenings in teahouses above 3,000m |
Down Jacket Quality Matters
Thorong La at 5,416m in pre-dawn darkness is one of the coldest experiences on any mainstream Nepal trek. A city-weight packable down jacket is insufficient. You need a mountaineering or expedition-grade down jacket with a minimum 600-fill power and a comfort rating of at least -10°C. Many trekkers who struggle on Thorong La are underdressed, not underfit.
Outer Layers
| Item | Specification | Notes |
|---|---|---|
| Hardshell jacket | Waterproof/breathable, all taped seams | Essential — both sides of circuit get rain |
| Hardshell trousers | Waterproof/breathable | |
| Gaiters | Low gaiters minimum | For snow on Thorong La pass day |
Head, Hands, Feet
| Item | Notes |
|---|---|
| Warm wool or fleece hat | For evenings and mornings above 3,000m |
| Balaclava | The single most underrated item — keeps face warm on Thorong La |
| Buff / neck gaiter | 1-2; versatile for face and neck protection |
| Lightweight gloves | For hiking in cool weather |
| Insulated waterproof gloves or mittens | Non-negotiable for Thorong La — frostbite risk is real |
| Merino wool socks | 4-5 pairs; vital for 15 days |
| Liner socks | 2 pairs; blister prevention |
| Trekking boots | Waterproof, ankle support, worn in before departure |
| Camp sandals or light shoes | For teahouse evenings and river crossings |
| Sunglasses | Category 3-4, UV400; critical — glacial reflection above 4,000m |
| Goggles | Optional; valuable if snowstorm catches you near the pass |
Sleeping System
| Item | Specification | Notes |
|---|---|---|
| Sleeping bag | -15°C rated (comfort, not limit) | Teahouses above Manang are cold; even -10°C bags feel insufficient |
| Sleeping bag liner | Silk or fleece | Adds warmth and hygiene over 15+ nights |
What the teahouses provide: Mattress, pillow, blanket (usually thin). Never rely on the teahouse blanket above Manang.
Navigation and Safety
| Item | Notes |
|---|---|
| Trekking poles | Both poles; essential for the 1,656m descent from Thorong La to Muktinath |
| Headlamp | 200 lumens minimum; USB rechargeable preferred |
| Extra batteries | For non-USB headlamp |
| Portable power bank | 20,000mAh; charging above Thorong Phedi unreliable |
| Whistle | Emergency signaling; weighs nothing |
| Emergency space blanket | Hypothermia insurance |
| Compass or GPS | Trail can be unclear in heavy snowfall near Thorong La |
| Downloaded offline maps | Maps.me works offline; download before departure |
| Pulse oximeter | $20-40; SpO2 monitoring above 3,500m — serious tool, not optional |
First Aid Kit
| Item | Why |
|---|---|
| Diamox (acetazolamide 250mg) | AMS prevention — consult doctor before trek |
| Dexamethasone 4mg | HACE emergency — guide administers |
| Nifedipine 10mg | HAPE emergency |
| Ibuprofen + Paracetamol | Headache, body pain |
| Oral rehydration salts (ORS) | Dehydration and stomach illness |
| Ciprofloxacin or Azithromycin | Stomach infections |
| Anti-diarrhea medication | Common on long treks |
| Antinausea (ondansetron) | High altitude nausea |
| Blister kit (moleskin, Compeed) | 15 days = foot wear |
| Athletic tape | Ankle support and general |
| Antiseptic and wound dressings | Minor cuts |
| Water purification tablets | Backup |
| Throat lozenges | Dry high-altitude air causes throat issues |
Hydration
| Item | Notes |
|---|---|
| Water filter | Sawyer Squeeze or similar — primary water treatment |
| Purification tablets | Backup; keep in daypack |
| 1L insulated water bottle (x2) | Insulated bottles prevent freezing above 4,000m |
| Thermos flask (optional) | Fill with hot water at Thorong Phedi for the pass |
| Hydration bladder | Optional; can freeze near Thorong La — carry water bottles as backup |
Hydration strategy: The circuit's altitude makes dehydration risk very high. Target 3-4 liters per day above 3,000m. Drink before you're thirsty. Urine should be pale yellow — above 4,000m, many trekkers become mildly dehydrated without noticing.
Electronics
| Item | Notes |
|---|---|
| Camera + extra batteries | Keep batteries in jacket pocket at altitude — cold drains them fast |
| Smartphone | Nepali SIM works in most villages; buy in Kathmandu |
| Portable power bank (20,000mAh) | Most important electronic item |
| Solar charger (optional) | Useful above 4,000m on sunny days |
| Universal plug adapter | Nepali, European, and Australian sockets all appear on circuit |
| E-reader or downloaded books | 15 days; rest days in Manang and Marpha beg for reading |
Hygiene and Personal Care
| Item | Notes |
|---|---|
| Biodegradable soap | Conservation area requirement |
| Hand sanitizer | Before every meal; stomach infections derail treks |
| Baby wipes | Essential above Manang where showers are less reliable |
| Quick-dry microfiber towel | Compact, fast drying |
| Toothbrush + toothpaste | Minimal |
| Sunscreen SPF50+ | UV intensity increases dramatically at altitude |
| Lip balm with SPF | Lips crack badly on Thorong La without protection |
| Moisturizer | Cold alpine air is intensely drying |
| Toilet paper | Some sections have no facilities |
Documents and Money
| Item | Notes |
|---|---|

| Emergency contact card | Laminated; carry in daypack |
| Cash (50,000-70,000 NPR) | No ATMs Chame to Jomsom; withdraw in Pokhara |
| Small bills | 100 and 500 rupee notes for teahouse payments |
