Description
The Pulse (previously known as the Atom+)
Trails are changeable. If you go on a long thru hike then your gear, clothing, food and water requirements will all change as the trail goes on. The Pulse is the answer – an ultralight pack that can adapt with you to meet the conditions.
The lightweight carbon frame and removable hip belt offer just enough support to help you when things get heavy, but are still flexible and light enough for true ultralight adventures.
Feel like you don’t need it? Take the frame out and leave it at home. Want to try hiking hipbelt-less? Take the hipbelt off and see how it feels

Find your hip measurement
Take the tape measure and wrap it around your hips bones (or where you wear your hip belt). Where the two ends overlap is your hip measurement, use the chart 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.
| Hipbelt Size | Inches | Centimetres |
| Extra Small | 28 - 30 | 71 - 76 |
| Small | 30 - 32 | 76 - 81 |
| Medium | 32 - 34 | 81 - 86 |
| Large | 34 - 36 | 86 - 91 |
| Extra Large | 36 - 38 | 91 - 96 |
| XXL |
38 - 40 | 96 - 101 |
| XXXL | 40 - 42 | 101 - 107 |
Perfect Hipbelt Fitment
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 |

The Pulse
Simple. Lightweight. Durable.
On a long thru-hike your gear, clothing, food and water requirements can all change. The Pulse is an ultralight pack that can adapt to the conditions of the trail.
EcoPak EPX200
Durable and lightweight, EPX200 is a recycled 200 denier face fabric with eco DWR finish, blue 45 degree cross ply and white recycled 70 denier backing fabric.
The EPX200 is our choice for The Atom+ due to its eco credentials, waterproof qualities, light weight and added durability.
Not too shabby on the eye either.
I have only taken it on a couple of overnights so far but really like it. I will give it a proper review at averagehiker.com when I finish my CDT thru-hike this year. That will really put it through its paces. The only thing I would change so far is the bottom and shoulder strap pockets. The bottom pocket material is a little too tight and the shoulder pockets are too tight for my iphone (small size). Everything else is perfect and I am hoping the pockets loosen as I use them more.
Traveled across a couple of islands in cape verdie
No issieus so far.
The lack of a back panel does make you rethink how you pack the bag tho 😆
Wow , I am impressed with how such a simple pack can be so comfortable .
Great features , comfy shoulder straps , good hip belt that grips your hips and a great shape making packing very easy .
An added bonus for me is that the frame is removable which enables you to roll the pack down so it’s not as tall and you can defeat budget airline hand luggage specifications and take it onboard the plane and save yourself a small fortune !
Excellent backpack.
Front clip is too small. It doesn’t close easily and keeps snapping off from the main perpendicular belt.
Change front Clíp.
Only used for day hikes so far but already impressed. The pack is very comfy and the features have been well designed. The bottom pocket, in particular, is great.
