How to Pack a 22L Running Vest for an Overnight
A 22L running vest is where overnight fastpacking starts to feel realistic instead of extreme.
You still need to care about volume, weight, and weather, but 22L gives you enough room to stop playing pure survival Tetris.
This is the kind of setup that works best when:
- The weather window is good
- You only need one night out
- You want to move fast and keep the pack close to the body
- You still want a real sleep system and basic safety margin
If the forecast is ugly, the water carries are long, or you want more camp comfort, I would still size up rather than force 22L to cover every situation.
The Reality of 22L
The main constraint is still compressed volume, not just base weight.
But 22L is a very different game from 15L.
You can carry a one-night kit that feels intentionally light rather than stripped down to the edge.
That means a realistic 22L overnight setup can usually support:
- Down insulation that compresses well
- A real bivy, small tarp, or compact shelter
- A short pad or even a narrow full-length pad
- Slightly more clothing margin
- More food flexibility
- A small stove if the rest of the kit stays disciplined
It is still not normal backpacking. It is still fastpacking. But it is a version that makes sense for more people.
What 22L Actually Buys You
Upgrade from 15L |
Why It Matters |
|---|---|
| Real shelter options | You do not have to rely on only the tiniest bivy-style setup |
| Warmer sleep system | A 20F-30F down quilt is much more realistic |
| Better pad choices | Sleep quality improves fast when you stop forcing the smallest pad possible |
| Modest cooking option | A tiny stove and pot become possible if the rest of the kit stays compact |
| More food margin | You can bring a more normal dinner and breakfast instead of pure snack survival |
| Better weather margin | An extra layer or slightly more protective shelter fits without wrecking the whole system |
My Honest Take
A true 22L overnight setup is easiest in:
- Summer
- Shoulder season with a reasonable forecast
- Known routes
- One-night pushes
- Trips where you want to move a lot and camp simply
It is much harder in:
- Long wet forecasts
- Cold alpine nights
- Trips with required bear canisters
- Multi-night food carries
- Long wet stretches
- Trips where you care a lot about camp comfort
The biggest tradeoff is still shelter and sleep volume. 22L gives you more margin, but a bulky synthetic bag, thick pad, and roomy tent will still blow up the plan fast.
The Two Versions That Actually Make Sense
1. Fast and Light No-Cook
This is the version I would choose most often.
| Category | What I Would Bring |
|---|---|
| Pack | 22L running vest |
| Shelter | Compact bivy, tarp, or small single-wall shelter |
| Sleep insulation | 20F-30F down quilt |
| Pad | Short inflatable or narrow full-length pad |
| Clothing | Worn running kit, puffy, rain shell, spare socks, thin beanie or buff |
| Water | Two front soft flasks plus a filter and optional extra bottle |
| Food | One dinner, one breakfast, trail snacks, no stove |
| Safety | Headlamp, phone, small battery, mini first aid, repair tape |
This is the version that feels properly fast and light.
2. Small Stove and More Comfort
This is the version that spends some of the extra 22L room on a better night.
| Category | More Comfortable Approach |
|---|---|
| Shelter | Small tarp or compact tent |
| Sleep insulation | Warmer down quilt |
| Pad | Better inflatable pad |
| Kitchen | Tiny stove, 550 ml pot, lighter, spoon |
| Clothing | Puffy, rain shell, spare socks, beanie, maybe thin gloves |
| Food | Simple hot dinner and coffee or tea |
| Comfort extras | Tiny pillow or small sit pad |
This is still not luxurious, but it is much nicer than the old 15L game.
What I Would Actually Pack
Here is the most realistic one-night 22L kit I can defend.
Sleep and Shelter
| Item | Notes |
|---|---|
20F-30F down quilt |
22L makes a warmer quilt much more realistic |
| Compact shelter | Small tarp, bivy, or compact solo shelter |
| Short or narrow pad | This is where better sleep becomes possible |
| Small pillow | Optional, but much easier to justify now |
Worn Clothing
| Item | Notes |
|---|---|
| Running shirt | Wear it |
| Running shorts or tights | Wear them |
| Hat | Wear it |
| Socks | Wear one pair |
| Trail shoes | Obviously |
Packed Clothing
| Item | Notes |
|---|---|
| Puffy | Still one of the highest-value items in the pack |
| Rain shell | Mandatory |
| Spare socks | One pair |
| Thin beanie or buff | Easy warmth for very little space |
| Sleep shirt or thin base layer | Optional, but now much more plausible |
Anything beyond that starts to feel expensive in 22L, especially if the shelter is not tiny.
Food and Water
| Item | Notes |
|---|---|
| Two front flasks | Usually the easiest vest carry |
| Small filter | Soft-flask-compatible systems work best here |
| Optional extra bottle | Useful for dry stretches or camp water |
| Dinner | No-cook works best, but a tiny stove dinner is possible |
| Breakfast | Bagel, oatmeal, coffee, bar, or a simple trail breakfast |
| Trail snacks | Enough for the moving hours, not an overflowing food bag |

Safety and Small Stuff
| Item | Notes |
|---|---|
| Headlamp | Non-negotiable |
| Phone with offline maps | Primary navigation |
| Small power bank | One-night size only |
| Tiny first aid kit | Blister care, meds, tape |
| Mini repair tape | Always useful |
| Emergency communication | Optional, but easier to justify in 22L |
| Trowel or wag bag | Depends on area and rules |
How I Would Pack the Vest
The packing order matters almost as much as the gear list.
Main Compartment
| Priority | Item |
|---|---|
| Bottom | Quilt in a dry bag or pack liner |
| Middle | Shelter and pad |
| Middle | Puffy and sleep clothes |
| Middle | Dinner and breakfast food |
| Top | Rain shell and any layer you may need quickly |
Back Panel or Outside Carry
| Item | Notes |
|---|---|
| Foam pad or sit pad | Outside if needed, but I would rather keep the system internal if possible |
| Trekking poles | If not in hand, use the vest’s pole carry |
| Wet shelter | Nice to separate after the first morning |
Front Pockets
| Item | Notes |
|---|---|
| Two soft flasks | Primary water carry |
| Snacks | Easy access while moving |
| Phone | One front zip pocket or chest pocket |
| Filter | Quick refill access |
| Headlamp | Easy to reach late in the day |
| Gloves or buff | Good to grab without unpacking everything |
Tiny Zipper Pockets
| Item | Notes |
|---|---|
| Mini first aid | Keep it compressed |
| Battery and cable | Separate from food if possible |
| ID, card, key | Obvious essentials |
What I Would Leave at Home
| Item | Why |
|---|---|
| Camp shoes | Still not worth it here |
| Big cook kit | If I cook at all, it should be tiny |
| Duplicate layers | 22L is better, but it is not a free-for-all |
| Heavy fleece plus puffy | Pick the better system for the forecast |
| Huge power bank | One night does not need it |
| Bulky toiletries | Shrink everything |
| Big tent | Defeats the point of the pack size |
The Simplest Possible One-Night Food Strategy
If I were trying to make 22L work cleanly, I would still keep food simple.
| Meal | What I Would Bring |
|---|---|
| Dinner | Tortilla + tuna or salami, or a single compact hot meal if I bring a stove |
| Evening | Tea or instant cider only if the stove is already coming |
| Breakfast | Bar, bagel, oatmeal, or coffee and snacks |
| While moving | Jerky, candy, bars, nuts, dried fruit |
The cleaner the food system, the better the whole pack rides.
When I Would Upgrade to a Bigger Pack
I would stop trying to force 22L and move up if:
- The forecast includes real rain
- Nights are properly cold
- I need a roomier shelter
- I am carrying more than one night of food
- The route has long water carries
- A bear canister is required
- I want noticeably more camp comfort
At that point the bigger pack is not failure. It is just the right tool.
Final Take
Yes, you can do a very good overnight out of a 22L running vest.
For me, 22L is close to the sweet spot for one-night fastpacking because it gives you enough room for a real system without losing the close, runnable feel of a vest.
The trick is still not magic packing. The trick is accepting a specific style of trip:
- One night
- Reasonable weather
- Compact shelter
- Compressed down insulation
- A disciplined clothing list
- Simple food
- Limited luxuries
That is still not traditional backpacking. It is fastpacking with sleep gear, just with a lot more sanity than 15L.
And if you embrace that honestly, 15L becomes realistic.
