Great running belt!

Originally posted on Under Armour

Yes, I recommend this

I really like this running belt for longer runs. Offers plenty of space for a large smart phone as well as an easy access pouch for gels if wanted. Easily adjustable and comfortable. Just did a 16 mile run with it and hardly noticed it was there. I would definitely recommend it!

Great running belt. Does not bounce at all!

This is a great running belt. Does not bounce at all when running. Only downside is it is very tight when I try to leave my phone case on.

I started using an app on my phone to track my running. Carrying my phone in my hand or putting it in a pocket was not an ideal situation. The speed belt does exactly what I need it to do.

As a new runner i wanted a running belt so that i can bring my phone with and not having to weigh down my shorts. This worked perfectly and i also like the easy access pocket. Good materials.

Very comfortable

Bought this belt to wear to physical therapy and the gym. I carry my wallet and keys in it while I work out. The belt is so comfortable, I hardly notice I’m wearing it! I went back to the store and bought one for a friend.
