Osprey Packs Daylite Plus Ultralight Backpack

Osprey Packs Daylite Plus Ultralight Backpack

Before we get into the features and benefits of this pack, it is important to mention that this will not be suitable for hiking. It is a lightweight backpack, but it’s not really designed to hold enough gear to survive months on the track. The Osprey Daylite Plus Daypack is exactly what the name suggests - a pack to carry in a day. It was designed for travellers who carry a massic backpack from place to place and need a smaller option when exploring for the day. 

With that in mind, it’s still a great lightweight backpack for hiking - but better suited for a day hike. It is made of polyester and weighs only 1.19 lbs. There are two main compartments - a large main compartment and a small pocket on the front. There are two side mesh pockets to carry things like a water bottle. In addition to that, it has a multifunctional interior pocket that can hold a table or water tank. You won’t run out of useful storage compartments to keep all your gear close at hand. 

On the back, there is the signature Osprey vented back panel. This is absolutely essential if you want to stay cool when trekking in the heat.

The comfortable shoulder straps and padded belt both have a daisy chain for clipping on items. Like other premium lightweight backpacks, this pack is also equipped with a sternum strap and the 3D mesh on the underside of the shoulder straps and waist belt - giving them more cushion and texture.

Granite Gear Crown VC 60 Ultralight Crown Backpack

There are also a few expandable storage compartments around the bag to keep your extra stuff, water bottles and other gear inside.

How to Pick an Ultralight Backpack? - Factors to Consider before Getting a Lightweight Pack 

Whether you’ve planned a truly epic hike or a simple weekend getaway, keeping the weight of the load on your back to a bare minimum is mega essential. A lightweight backpack will allow you to go a long distance with less energy, and obviously will make your entire hike much more enjoyable.

Lightweight backpacks are no longer unique to long-distance hikers. The whole outdoor leisure and travel industry is caught up in the ‘lightweight’ game, and the reason for this trend is very simple: hiking with a lightweight backpack is much more pleasant. Your backpack is one of the heaviest items you will bring with you, it is therefore very wise to start by choosing a backpack model with optimal weight. 

Whatever your purpose is, we hope that our advice in choosing an ultra-lightweight backpack will help you in the quest for the perfect backpack for your needs, which will make you feel comfortable on your excursions, for many years to come. 

What to Consider When Choosing an Ultralight Backpack?

Price: Buying a sturdy and lightweight backpack shouldn’t force you to drain your savings account. With that being said, with proper maintenance, your backpack will theoretically be with you for many years to come and you will cover thousands of miles with it, so investing in the right gear is no foolish thing. 

Weight: Your backpack will be one of the heaviest things on your trip, it is therefore very important to choose it correctly in order to minimize the total weight of your load. 

Frame: The lighter your backpack is, the less it needs for a frame. If you plan to transport more than fifteen kilos during your expeditions, then opt for a more elaborate frame. 

Volume: The volume of your backpack will determine the amount of gear you can fit in. If you are looking for a backpack for casual travelling purposes, then a pack of 20-36 litres will do a wonderful job. On the other hand, most experienced hikers will go for a 40 or 50-litre bag which will allow them to fit all of their gear even on long and technical expeditions. If backpacking is new to you, you may prefer to opt for a larger backpack first, and adjust its load little by little. If you plan to hike in more wintery conditions, this choice will be very reasonable, since it will allow you to store heavier and larger equipment, specifically for this type of excursion. 

Design: A backpack doesn’t have to be very sophisticated. Oftentimes, the brands with the most basic and clean designs are the ones with the best products. In the end, your hiking bag is just a bag in which you store your equipment. And the one with an infinite number of pockets, straps or compartments may not be the best ones. The best backpack is the one that suits your needs the most. 

Materials: Most lightweight backpacks are made from just one or two main materials: ripstop nylon or Dyneema fibre. Both materials are very durable and functional. 

Fit: Fit is an important factor in a backpack, but it’s also one of the most difficult criteria to assess until you end up with your backpack full on your shoulders. Measure your bust size and your waistline before ordering and it should be fine. 

Return conditions: Check the return conditions of the website you’re purchasing from. It is possible to return a backpack that has not yet been used, obviously having to respect the authorised return deadline. You can proceed with the purchase of the model you have selected, then try it out at home as soon as it arrives, and exchange it if it doesn’t fit you. Bear in mind that a backpack that doesn’t fit your back size will leave you with discomfort in the long run. 

The Key Elements in a Good Design of an Ultralight Backpack

Centre Compartment: Most lightweight backpacks have the main compartment to store most of your gear. And that’s all you need. The other additional compartments usually add unnecessary weight and complexity to the backpack. 

The hip belt: A good hip belt is absolutely essential for any backpacking bag. The hip belt is responsible for directing almost all the weight of your bag on your hips, which avoids exhausting the shoulders. These belts should be comfortable, preferably with padded foam. 

Shoulder straps: These straps will carry a lot of weight on your backpack. So you want them to be as comfortable as possible, padded and well-positioned to avoid irritation or uneven pressure points. 

Pockets on the hip belt: In theory, you won’t need many breaks during your journey, so it is convenient to have a few useful items close at hand, such as snacks, sunscreen, lip balm, mobile phone, camera, etc. Most of the hiking backpacks have hip belts integrated with pockets, but if they don’t, we recommend purchasing a separated hip pack for these items. Check out our Hip Pack collection.

Water bottle pocket: Staying hydrated is essential when travelling, hiking and walking long-distance, so it is important to be able to access your water bottle easily. 

Waterproof feature: In general, it’s never a good idea to completely trust your backpack when it comes to waterproofing. Even waterproof zippers made from the most sophisticated materials will leak over time, so we recommend that you always protect your most important items (sleeping bag, clothes, electronics etc.) in small separate waterproof bags, or plastic bags, inside your backpack. 

Chest straps: Chest straps are found on most lightweight backpacks on the market. They allow you to connect the shoulder straps to the level of your chest for a more stable and pleasant feeling. Some lightweight backpacks are equipped with a small elastic or an emergency whistle. 

Load straps: The load straps can adjust the strap length between your shoulders and the backpack. This can help take some of the weight off your shoulders, shifting it more to the front of your shoulders and onto your chest.

Are ultralight backpacks worth it?

Yes, they are definitely worth it! If you compare a lightweight backpack with a normal backpack when storing the same amount of load, the lightweight backpack will be much more comfortable on your back as it reduces the overall weight. Obviously, you don’t want to carry a heavy backpack on long walks - this is where the ultralight backpacks come in - to leave you more room to store your necessities, cover more miles and help to reduce back pain. 

No matter what your purpose is, going on a backpacking trip, or getting a backpack for daily use, or specifically hiking on long trails, an ultra-lightweight backpack is your best bet! 

What is considered an ultralight backpack?

There are many factors when it comes to deciding whether or not a backpack is ultra-lightweight. While there is no official definition of a backpack to be considered ‘ultralight’, an ultralight backpacking experience is when the base weight of a fully loaded backpack at the start of a trip is under ten pounds.

How much weight should you carry on an ultralight backpack? 

You must have known the guideline on how a backpack should fit your body:

  • For loaded backpacks: they shouldn’t weigh more than 20% of your body weight
  • For loaded day hiking packs: they shouldn’t weigh more than 10% of your body weight

But this isn’t always the case. It works for some people and doesn’t work for others. In addition to this rule, there are other factors that play a big part in the total weight of your backpack*: 

  • The duration of your trip: The longer your trip is, the more gear and food you carry with you. 
  • The season or weather: If you are travelling in low-temperature areas, you will need to bring heavier and more clothing items with you than those hot summer days.
  • Personal preference:  Some people prefer changing clothes multiple times over days while others can wear one item for several days. Especially when you go backpacking/hiking, this factor can make a difference to your overall weight.
