Easy-access bottom pocket with trash port made with Dyneema stretch fabric.
Large front pocket
Made with Dyneema stretch fabric. Can hold 5L, not included in the total volume.
Side pockets
Two 2.5L forward-facing, deep and low side pockets made with 210D Robic Extreema. Each one is big enough to keep 2 x 1L Smartwater bottles steady, yet low enough to reach whilst the pack is worn.
Front zig-zag elastic
Removable and designed to be able to store a folded Z-rest or assist with air drying your clothes.
Side elastic with Lineloc
These are there to secure a pole or tent stakes when stored in the side pocket. If you are wanting to compress the bag, we recommend switching to a non-stretch cord.

How to measure your Torso
Follow our 5-step guide to find the perfect fit.
Please note!
Your torso size is not necessarily linked to your height or weight. If you take a large t-shirt it won’t necessarily mean your torso is a size large. So please, measure before buying.
Finding an accurate measurement is simple, but you may find it easier if you ask someone to help you measure up.
1. Find your C7 vertebrae
Tilt your head forward and find the bony bump at the base of your neck - this is your C7 vertebrae and the top point of our measurement. Place the top of the tape measure or string here and then tip your head back up to neutral.
2. Find your iliac crest
Place your hands on the top of your hip bones with your thumbs pointing towards your spine. Draw an imaginary line between your thumbs, where this line meets your spine is your iliac crest. If you are measuring on your own, then adjust the waistband of your trousers to sit at this point and tighten your belt - you will measure to the top of your belt.
3. Measure the distance between the two
Measure from the C7 down to the iliac crest (or your belt if you are measuring solo): make a note of the number - this is your torso size.
4. Measure again
A wise person once said, measure twice: cut once. Custom packs are non-refundable, and returns are painful for everyone, so take the time to get this right. Apply a little common sense at this point - if you normally wear Small t-shirts but have measured as an X-Large, maybe let's go back to step 1! If you are unsure, please send us an email and we can help.
5. Torso size
Once you are satisfied with your measurement, refer to the table below to find your size. If you are in between two sizes, going for the smaller of the two will ensure a good fit - trust us on this.
Torso Size | Inches | Centimetres |
Small | 15-17 | 38-43 |
Medium | 18-19 | 46-48 |
Large | 20-21 | 51-53 |
Extra Large | 22-23 | 56-58 |
