Under Armour Undeniable 5.0 Medium Duffle Bag
The Under Armour Undeniable 5.0 Medium Duffle Bag is a practical choice for carrying your golf gear, training kit or everyday essentials. Made from durable polyester, it features UA Storm technology for a highly water-repellent finish to help protect your belongings. The tough, TPU-coated and foam-lined base and side panels add durability and help the bag maintain its shape.
With a generous 58-litre capacity, there is plenty of room for your kit. Storage includes two water bottle slip pockets, a zipped valuables pocket and a large vented compartment for laundry or shoes. Internal slip pockets and a large front zipped pocket provide extra space to keep your belongings organised.
The removable, padded HeatGear shoulder strap adjusts for comfortable carrying and stows away inside the pocket when not needed. A padded top grab handle and MOLLE webbing attachment points add further practicality.

I was looking for a new bag for week night stay overs and stumbled across this bag, the golf shop had the bag in stock at a competitive price so I placed an order and received the bag several days later. Very good service from the golf shop.
