Under Armour Undeniable 3.0 Medium Duffel best Gym & Travel Bag

I ordered this bag in size small for the gym, and it fit my essentials with room to spare. I packed up my protein shaker, three 16oz water bottles, a small backpack, gloves, towel, diapers, wipes, snacks for my kids among other necessities and could still fit maybe 20% more. Marked with the classic oversized UA logo and built with incredibly durable materials and tons of storage space, this is your go-to duffle bag for everyday performance. It’s lightweight but feels well made, and the material feels like it should be easy to clean. I am so happy with this bag!

I literally store everything I need for the gym into this bag my under clothes, shirt, pants, shoes, a bag to keep my dirty clothes in, shower towel, workout towel, earbuds, Kindle, shaker cup, and shake mix. Even after I have all that in the bag, there is still a bunch more space left that is left unused.
