Product Description Explore The Range Sub90 Running Pack Towel & Seat Cover Sub45 Running Pack Running Belt & Leash

Review: Super handy for running - I’ve bought other bladders from this company before, which have lasted for well over a year (still going) and recommend them to friends. They’re really light weight and are great to fit in your pocket when snowboarding or in a small bag when out and about. I’ve never had any issues with leaking and although initial they do have a funny taste (not too bad), that quickly goes. This one seems much the same - bought for running as I hate carrying part empty bottles - these reduce in size as you drink, so there is never air in them. The holder seems weak made and fits well. I love the pocket at the front - great for keys and a bank card for emergencies.
Review: Does the job - Wanted a small soft bottle to carry water in when snowboarding and this has proven to fit the bill. No plastic or rubbery taste although not sure how hygienic it will be long term

### ⭐⭐⭐⭐⭐ Super handy for running
*by Z***D on 2 September 2025*

They’re really light weight and are great to fit in your pocket when snowboarding or in a small bag when out and about. I’ve never had any issues with leaking and although initial they do have a funny taste (not too bad), that quickly goes.

### ⭐⭐⭐⭐ Does the job
*by D***E on 21 March 2026*

Wanted a small soft bottle to carry water in when snowboarding and this has proven to fit the bill. No plastic or rubbery taste although not sure how hygienic it will be long term

### ⭐⭐⭐⭐⭐ Functional, works well and handy pocket for keys and essentials.
*by M***N on 25 March 2025*

I was impressed with how it felt on a run, fit my hand well (glove size 9) and the extra pocket is great for small things like keys and inhalers, or Gu.(better than things jingling in a pocket). Using is great and it's easy to take occasional sips without breaking a stride. Reflectors on the straps and side are a nice touch. Doesn't leak or drip. Bit of a funny "new" taste but better with some soapy water and a soak in mild citric acid. I'm sure it'll go with use (edit: it has) Ideal for 5-10k ultras.
