In plain English
An overnight backpack carries everything for one night outdoors: a small tent, a sleeping bag, a sleeping pad, a little food and a way to cook or eat it. It is bigger than a day pack but smaller than a pack for a week-long trip.
The trickiest part is not the tent but the bed. A warm sleeping bag can be puffy and take up a lot of room, like a winter duvet stuffed into a pillowcase. A thin summer bag packs small. So the right pack size depends a lot on how cold your night will be.
Fit is just as important. Load the pack with some real weight before you judge it, because an empty pack always feels fine. The weight should rest mostly on your hips, with the shoulder straps snug but not squeezing.

What should you look for in an overnight backpack?
Torso fit matters more than any other spec on an overnight pack, since two 35–45L packs from different brands can carry very differently depending on frame length and hipbelt shape. After fit, prioritize empty pack weight, suspension type, and how cleanly the pack's compression straps cinch down for a load that's lighter than what the pack could technically carry.
Measure torso length from the C7 vertebra at the base of the neck down to the iliac crest at the top of the hip bones, not from overall height. Most packs in this size range use small, medium, and large torso sizes, or an adjustable suspension within a set range, and hipbelt sizing is set independently. A correctly fitted hipbelt carries, by a common rule of thumb, roughly 80% of the load, which matters even on a lighter overnight pack, since shoulder discomfort shows up quickly on a poorly fitted hipbelt regardless of how little weight is inside.
How much should an overnight pack weigh empty?
Because an overnight trip carries less food and fuel than a longer trip, hikers have more room to prioritize a lighter empty pack without sacrificing comfort on the load it actually needs to carry. Standard internal-frame packs at this volume commonly weigh in the 2 to 4 lb range, while frameless or minimalist ultralight packs built for experienced packers with light gear lists can weigh under 2 lbs. The trade-off is load support: a frameless pack transfers less weight to the hips and works best for total pack weights under roughly 20 to 25 lbs, which many overnight loads fall within, but not all.
Internal frame vs minimalist frameless packs
- Standard internal-frame packs use aluminum stays or a perimeter wire frame to transfer load to the hipbelt, carry heavier loads more comfortably, and suit hikers new to backpacking or anyone unsure how light their kit will end up.
- Frameless or minimalist packs cut frame weight and structure, ride well only when packed correctly with a rigid item like a sleeping pad against the back panel, and suit experienced packers with a dialed-in, lighter-weight gear list.
Who an overnight pack suits
An overnight pack in the 35–45L range suits hikers doing single-night trips with a standard or lightweight three-season kit. It's generally not the right size for hikers who regularly stretch to two or more nights, where a 45–55L weekend-oriented pack fits the added food and fuel more comfortably, and it's too small for bear-canister or winter trips that need extra volume regardless of night count.
Honest trade-offs to weigh
- A lighter empty pack generally means less padding, a simpler frame, and less external organization than a heavier, more structured pack at the same volume.
- Minimalist frameless packs save real weight but demand more careful packing and suit a narrower range of total loads than a framed pack.
- More external pockets and a floating lid add convenience but add weight that works against the point of choosing a smaller, lighter pack in the first place.
- A pack sized precisely for one night rides with less unused space than a larger pack, but it leaves less margin if a trip runs long or weather forces an extra layer.
How to decide between two similar overnight packs
When two packs both fit your torso length, compare empty weight against frame type first: a frameless pack only makes sense if your total loaded weight reliably stays light. Beyond that, check how each pack's compression system performs when it's only half loaded, since a one-night trip rarely fills a 40–45L pack completely, and a pack that cinches down cleanly for a light overnight load will carry more predictably than one optimized only for a full pack.

Is 35 to 45 liters really enough for one night?
Sources draw the line in different places. This page suggests 35 to 45 liters for single-night trips, while the Washington Trails Association says a 45 to 50 liter pack should fit gear for a standard one- or two-night trip.1 Both can be right: the smaller range assumes a compact, lightweight kit, and the larger one a more typical first kit.
Two things push you toward the bigger number. The first is base weight and bulk: ultralight kits, generally a base weight of 10 pounds or less,2 tend to pack smaller too. The second is a bear canister, where required. Typical canisters are about 8 by 12 inches,3 a rigid block that eats a real share of a small pack. Rules are park-specific, so check current rules for your destination first.
Sleep system: the item that sets volume and warmth
Sleeping bag ratings are more precise than they look. Under the ISO system, the comfort rating is the temperature at which an average woman sleeps comfortably in a relaxed position, while the limit rating is where an average man stays in thermal balance while curled up; the extreme rating marks serious hypothermia risk and is not a target.4 Choosing by the comfort rating usually means a slightly warmer, bulkier bag, which is worth planning pack volume around.
The pad matters just as much. Sleeping directly on the ground chills you through conductive heat loss, and a higher R-value means a pad resists heat flow better.5 Big Agnes suggests an R-value of 2 or lower for summer and 4 to 4.8 for spring through fall, because shoulder seasons still bring cold nights.6 Thicker, warmer pads often pack larger, which is one more reason to size the pack after the sleep system.
Fitting an overnight pack before the first night
Big Agnes recommends fitting a pack with 10 to 20 pounds of weight inside,7 and Hyperlite notes that height is not a reliable proxy for torso length, so measure.8 Osprey says a correctly sized hip belt leaves a 3 to 6 inch gap between the hip-pad tips when tightened.9
Strap angles vary by brand. Big Agnes sets load lifters at 45 degrees,7 Deuter says 30 to 45 degrees works best,10 and Alpkit gives 25 to 45 degrees from horizontal.11 The hip share is contested too: WTA says around 80% goes to the hips,1 while US Army doctrine estimates about 30% with a frame and hip belt.12
Frequently Asked Questions
What size backpack do I need for one night?
Most one-night trips fit comfortably in a 35–45L backpack, depending on gear bulk and season. Minimalist or lightweight packers can often manage with 30–35L, while hikers carrying a bulkier kit or extra layers may prefer the upper end of that range.
Can I use a daypack for an overnight trip?
A standard daypack under 30L usually can't fit a shelter, sleep system, and cook kit together, and most daypacks lack the hipbelt support needed to carry that weight comfortably. A dedicated overnight backpacking pack with a real hipbelt is a better fit even for a single night.
Is a frameless pack a good choice for a first overnight trip?
Generally no. Frameless packs demand careful, experienced packing to ride comfortably and offer less margin for error. A standard internal-frame pack is a more forgiving choice for a first overnight trip, with a frameless or minimalist pack better suited to later trips once your gear list is dialed in.
