FAQ's
What is a running vest used for?
Running vests allow runners to comfortably carry hydration, nutrition, and essential gear during longer runs. Unlike traditional backpacks, running vests are lightweight, close-fitting, and built to minimise bounce while running.
How should a running vest fit?
A running vest should fit snugly against your body without restricting breathing. Ideally, it should feel secure with minimal movement while running, and the adjustable chest straps should allow you to customise the fit for comfort over long distances.
Is a 5L running vest enough for long runs?
Yes, a 5L running vest is ideal for most long runs, races, and marathon training. It gives you enough space for hydration, energy gels, a lightweight layer, and small essentials without adding unnecessary bulk or slowing you down.
What can you carry in the Solus 5L running vest?
The Solus 5L running vest is designed to carry soft flasks, nutrition, keys, a phone, and lightweight layers. With multiple front and back storage pockets, it allows easy access to essentials while on the move.
Is this running vest suitable for trail running?
Absolutely, the Solus 5L is well-suited for trail and fell running. Its secure fit, breathable materials, and multiple storage options make it ideal for carrying essentials across uneven terrain.
Does the Solus 5L running vest bounce while running?
The Solus 5L running vest features a no-bounce fit. Its ergonomic design and adjustable chest straps help keep the vest secure and stable, even during faster-paced runs.
Can you use a running vest for marathons?
Yes, running vests are perfectly suited to marathons and races. A lightweight hydration vest like the Solus 5L allows you to carry fluids and nutrition comfortably so you don’t have to solely rely on aid stations.
Are running vests better than hydration belts?
Both are good, but running vests often provide more storage and better weight distribution than hydration belts. They are a popular choice for longer distances, trail running, and races where carrying extra gear is important.
How do you clean a running vest? - Care Instructions

- Do not bleach
- do not tumble dry
- Do not iron
- Do not dry clean
- Do not iron print
- Do not use biological detergents
- Do not use fabric softener
- Dry away from heat

What size running vest should I choose?
The right size running vest should feel snug but comfortable. Check the sizing guide and adjust the chest straps to ensure a secure fit that doesn’t move or chafe during your run
