Which of our day packs, backpacks or bodypacks are right for you? This guide will help you choose the right travel day bag or lightweight waterproof backpack for your overnight camping trip.

Our pack model range is divided into different families, based on the primary use. The families:


Our highly versatile travel day bags will carry all your needs for one day’s activities. Whether an urban excursion, cycling adventure, walking in the country, or a hiking, skiing and climbing adventure, our Daylite Packs are perfectly suited for your needs. Balance Pockets and Bags can be added to increase capacity, optimize gear access and minimize effort and strain. Superb balance is the delightful bonus!


These models, from daypack to expedition size, are optimized for fast and light adventures in the wilderness. Balance pockets are standard equipment on these models so the volumes specified include them. Find the day pack or backpack that's the right size for your needs.


Use these models for all overnight back country and climbing adventures. Balance Pockets or Bags should be added to achieve the most outstanding benefits over conventional packs. The volume of the Pockets you choose should be added to the pack volume to determine the total capacity. This is the lightweight waterproof backpack that will see you through every trail!


Because they have a long range of back length adjustments, The Daylites and Ultralites (day to mid-volume packs) i.e. Marathon & Mountain Magic, Flow-Mo Friend, Liquid Agility and Mobile Intention have one back length. These models also have sewn in hipbelts in one size to fit all body sizes.

All larger models of Ultralites and all the Stronglites come in two back lengths, Short and Long. To determine which size is best, you need to determine your back length: Measure the distance from the top of your hip bones to the mid- point of your shoulder (where the shoulder strap goes over the shoulder) to determine your back length.

For accuracy, stand with your back against a wall with a hard covered book and pencil in hand. Place the book vertically against your side with the bottom edge of the book resting on top of your hipbone and the back edge against the wall. Mark the height of the lower edge of the book on the wall. This is the height of the top of your hips.

Now place the book vertically by the side of your head, with the back edge resting against the wall and the bottom edge resting on the mid-point of one shoulder (half way between your neck and the end of your shoulder - this is where the center of the shoulder straps should lie). Mark the height of the bottom edge of the book on the wall. This is the height of your shoulders.
Now measure the difference in height between the 2 marks on the wall - this is your back length.

  • If your back length is less than 15” (38 cm), choose the short: S
  • If your back length is greater than 15” (38 cm), choose the long: L

WHAT IS MY HIPBELT SIZE, Small, Medium or Large?

Our large models with Pelvic-Form Hipbelts come in 3 hipbelt sizes. The medium size, M is standard. To decide whether this will fit, use a tape measure to determine your waist size, as the top of the hip belt goes around your waist.

If this distance is less than 33.5” (85cm) choose the S size, if it is greater than 37.5 ” (95 cm), choose the L size.


The volume of pack needed for a certain length of trip varies considerably between individuals. Gear choice, season and terrain are also determining factors. To know what model we recommend, we need to know:

  1. Whether you need a long or a short back length
  2. The maximum volume you need (in liters)
  3. The type of activities you do, e.g. Hiking/ tramping, mountaineering, running, biking, etc.
  4. The terrain: e.g. Rough, bush wacking, etc. (you need a Stronglite); tracks and open country (an Ultralite is good).

Packing your gear in a pack of known volume is a good way to determine your volume requirements. Know that our Ultralite family includes the Balance Pockets as standard; therefore the specified volume is with the Balance Pockets. With the Stronglites the volume specified is only for the pack itself, so the addition of Balance Pockets will increase the total volume, accordingly.

Also consider the longest trip you will do with the pack and the gear required. This determines the volume of pack needed. Determine how you will most often use the pack, and choose the most appropriate family for those needs.

If the most appropriate family for your needs is a Daylite, Stronglite or Travelite you will need to add the volume of your preferred Balance Pockets or Balance Bags to the volume of your pack to get the volume to match your requirements.

If your appropriate family is the Ultralites, the volumes quoted include the balance pockets which are standard equipment in this family.

NOTE: We strongly recommend using Balance Pockets or Balance Bags in all situations. The reduced energy use and body pain compared to carrying all your load behind in a backpack cannot be emphasized enough! The instant gear access of the pockets also increases efficiency, as you do not have to stop and remove the pack to access items needed during the day. Specific purpose Balance Pockets, Bags and clip-on accessories allow you to customize your pack for varied activities.
