## Description

WINDCHASER Bike Backpack, Waterproof Breathable Cycling Bicycle Rucksack, 10L Mini Ultralight Biking Daypack Sport Bags Gift for Fitness Running Hiking Skiing Trekking : desertcart.co.uk: Sports & Outdoors

Review: Well designed and robustly made small cycling or running pack - I’m often wary of seemingly cheap bargain products that look good on desertcart but turn out to be shoddy. I’ve only used this a few times so far but very impressed with the design. Seems solidly made. Nice design features include a discrete port for hydration tube on the top and a nice added feature is the small Velcro tab in the main compartment to hold hydration bag in place. The medium compartment has lots of pockets to hold wallet phone etc plus there’s a small compartment for keys or snacks etc. There a nice attachment point to fix a small clip on rear cycle light as well. Shoulder straps are good and robust and all in all it’s a superb lightweight well made pack. You won’t get much more in than a 2 litre hydration bag a lightweight waterproof and a few odds and ends in it but it does want it’s meant to very well. Very happy with it
Review: Highly visible, versatile and comfortable - Excellent quality, packed with pockets and compartments, snug and comfortable fit, double abdomen and chest straps and highly visible colour. Very happy with this!

## Questions & Answers

**Q: 10L backpack can hold an ipad, an iphone7, and some drinks and snacks?**
A: Yes. There is no problem, 10L backpack can be loaded with an ipad, an iphone7, a 2L water bag and some small snacks or fruit.

**Q: Does it include a hydration pack?**
A: No it doesn't.

**Q: What is the max length of the waist straps?**
A: Waist straps can open up to 76 centimetres

**Q: Can it hold a pair of shoes, trousers and a shirt and I can still run comfortably?**
A: It’s the shoes that are awkward but you might just squeeze them in. I got a pair of rolled up jeans, folded jumper and shirt in ok but it’s the depth which you may struggle with for shoes. It’s long and just about wide enough but you may struggle to get them in depth wise. Saying that I was trying trainers with quite a thick sole. If you put them in at funny angles you might just be ok but you’ll only get in a shirt and trousers as well. It’s great if you are running to work as the bag is small and quite comfy but the squeeze does crease the clothes.

Very good rucksack, only slight issue is one strap is twisted and I cannot untwist it. Otherwise be pleased with the bag. Looks like the picture.
