Perfect size for those quick access items

The reason I picked up this small bag was to use for small items and my water bladder for skiing. I get easily dehydrated when I’m on the mountain and if I’m not carrying water around with me I’ll go a whole day without hydrating. This bag fits my 1 liter silicone bladder as well as all the essentials that I need to keep on me (phone, chap stick, credit cards, ID, etc.) nice and compact and easily accessible. I had a small bag before this one that just couldn’t fit everything without the need for removing things. A couple features I love are the zipped pockets on the inside that keep important valuables like cash and cards from accidentally slipping out while I get my phone out to take photos. I love that it integrates as a hip strap for the pack pack as well. When I travel, which I do a lot of, I usually only take a back pack. While that’s great for flights it’s not optimal when you’re walking around the city. This feature, of being able to remove this bag from the pack pack helps me stay minimal but not without the essentials I need.

Great sling.

I have used this sling over and over again when traveling. It is comfortable, and has secure straps. There is a lot of room for several items. Love it, and purchased another one for my wife.

Slick sling

This product is highly functional, with many subdividers for organization, but it also looks great too. It's slick, sleek, and stylish.

Great sling bag

I've been using it for a couple of weeks and I can say it's a great sling bag - right what I've wanted. It's not baggy and quite flat while wearing. At the same time there is enough space inside to fit a passport, a phone, keys, a small first aid kit, a pair (or even two) of sunglasses, a cardholder, a small pepper spray and maybe smth else. The belt length is easy to change and it's also very comfortable. The only thing is that on me it slides a little bit off the center of the chest, but that's not a problem at all. The material feels very durable, the inside cloth is very soft and feels great. Pockets are easy to open and it's also good that there are not too many of them. Highly recommend this bag.

Exactly the right size

The Aion sling bag is perfect for holding all of the daily items that I carry. Holds my cell, keys and wallet all in one bag that I can easily reach. Even with all those items there is still room for several items. The bag construction and material are durable yet stylish. Thule did not disappoint!
