I have the Zerk 40, but don’t always need the extra carrying capacity. The Zerk 25 is ideal. Well fitting with great features. Comfortable. Will likely not get to use it until the Spring, but having used the Zerk 40, my guess is that I will be pleased with this purchase.

Nice size.Well insulated. Solid zipper

I purchased the Tour for hiking to carry snacks, essentials and water, but tried it one day to just ride to work on my bike. Holds my 13" laptop, water, exercise journal, glasses, keys and EDC knife and flashlight. My Tour is black, but the silver-grey accents are visible at night, making my ride feel safer. I used the strap at first that came with the pack, but my hubby purchased the suspender straps for me making it sit a bit more snuggly. I am just under 5ft tall, 112lbs, so the tour on its own wobbles on my hips a bit when I carry the water bottles on the sides, but with the suspender straps it sits snuggly on my hips and back and I don't have the shoulder pressure from a traditional backpack. I am enjoying the Tour more now that it serves multiple purposes. Great buy and great customer service when I was deciding which pack would be best given my petite size.

You have shared a tool that will impact new wildlife rehabilitators for many years. Our last volunteer class was with 4 standard duffle bags and two shoulder bags , wasn’t the ideal set up for teaching.

Ideal for trainers to keep supplies and materials organized and travels easily
Highly recommended for life

Great storage bags for our van trips. We each pick a color scheme and that way we know which bag to grab with our stuff. Love these! Keep making them as we have been using a version of the hauler bags since our tent camping days.

It’s nice to find a running vest style pack for bigger guys instead of the normal twig sized running vest packs. Lots of pockets which I like. The bag is big enough for a thru hike if your gear is dialed in for an ultralight kit. I bought mine off a different site that had a sale going on. I like the blue but wish I had gotten the gray version instead.

This is a really well built pack with a surprisingly large storage capacity.

Great product. Prompt shipping.

The tour pack is working out fine for my long walks, but it needed a little help.

The strapettes are just the ticket. 👍🏻

I have a “spare tire” which tends to push the pack down and cinching it tighter gets uncomfortable. The included shoulder strap is great when the pack is used as a shoulder utility bag, but not entirely useful for redistributing weight when worn around the waist.

Strapettes to the rescue, and unlike a backpack, they do not trap heat across your back. A win-win.

I mostly walk on pavement and these seem to work better than the onesi had.

Great for day hikes!

I needed a smaller lumbar pack for hiking with my dog and this one is perfect. I am 5’5” and 140lbs and this pack fits my waist. I definitely think it was designed for a slightly bigger body frame but it actually fits very comfortably. The water bottle pockets work very well and I don’t notice my arms hitting them while walking. The body of the bag has two pockets that fit quite a few items. And the stuff pocket on the outside was an unexpected perk. Overall, love the pack. Would definitely buy again.

Love this! Holds everything I need for a day hike.

A great addition to a fantastic pack
