Is the Pingora Impulse 11 Hydration Pack Worth It?

Here's my first look. This 11-liter pack has some great features right out of the gate:

• Running vest-style pockets on the shoulder straps
• Hip belt pockets (yes!)
• Dual sternum straps with adjustable toggles
• Trekking pole attachments

But there are also a few things that gave me pause:

• The exterior pocket doesn’t stretch
• No women’s-specific sizing
• It's pretty compact—maybe too compact?

I’m not sure yet if it’s the right pack for me, but here’s what I’ve noticed so far. Let me know if you’ve used this pack or have questions—happy to follow up with a full review.
