Prefecf rucksack

Prefect for gym use or just when you need a bigger bag on the run. Love it.

Fonctionnel et discret !

Léger et résistant. Les bretelles sont confortables et s’adaptent à la hauteur de dos. Tissu déperlant, imprimé pas salissant. Un zip permet d’ouvrir de part et d’autre le soufflet pour agrandir la largeur du sac. Ravie de mon achat !

Great Bag

This is a great alternative to the drawstring bags. Comfortable shoulder straps and great look. [This review was collected as part of a promotion.]

Fitness performance. Compressions, tanks, footwear

Have been a huge fan of the brand for years. For me it begins in the weight room and sky rockets from there. From footwear to the performance clothing, the brand has done all and then some. Order from under Armour every week and will continue to. [This review was collected as part of a promotion.]

Love it!

Very comfortable to wear (for me and my bf-I'm 5'4 and he's 6'1). Nice and light, and fits alot when it's expanded. Love the colour! (exactly as pictured). I own quite a few backpack/sacks, and this is by far my favourite. [This review was collected as part of a promotion.]

Sack pack

Bought the pink color for valentines for my wife. She works out every day and I want her to match with her under armour apparel. I was surprised how durable and thick it is and now she uses it for her workout gloves, knee pads, and jump rope. If any drawback it does not have an exterior pouch for her water drink but it is a great gift add on item. [This review was collected as part of a promotion.]


Best "sack pack" around. Comfortable to use, plenty of room. It will be much more useful than a regular sack pack. It will not only be useful as a quick overnight bag, but as a catch all bag when visiting a theme park.

Nice Size Comfortable Bag

Purchased two of these bags, one for myself and my partner. I use mine for my gym gear, fits everything needed comfortable. Trainers are a squeeze but they are an 11. Wouldn’t over load bag but is comfortable with the right weight in it. Partner uses hers for books and work stuff. Holds on back well but most comfortable when using the two handles

Excellent Product would recommend to anyone

Excellent items very useful, comfortable and easy to use
