{"reviews":[{"id":6561132,"locale":"en_US","rating":4,"title":"Mystery Ranch Catalyst 18","text":"The overall size is good. The internal zippered side pockets are small & awkward shaped. I'd have liked an exterior water bottle sleeve. The 3-way exterior zippers are a little fussy. I got the 18 & the 3-way zippers aren't necessary, you can see the entire contents of the bag without it. But, my biggest gripe, are the 3-way external zippers feel. I'd like to rip it open to expose the interior but often one of the zippers catch or resist. The overall mechanism isn't smooth. Overall I like the size and padded straps. I'm on the lookout for another more full featured 18l sized bag with laptop sleeve","textLength":612,"csFlag":false,"inappropriateFlag":false,"reviewedFlag":false,"autoModerated":false,"published":true,"incentivized":false,"upVotes":0,"downVotes":0,"orderId":null,"dimensions":[],"responses":[],"tags":[],"media":{"photo":[],"video":[],"audio":[]},"user":{"nickName":"M3guy87","firstName":null,"lastName":null,"emailAddress":null,"externalId":null,"city":"Los Angeles","state":null,"country":null,"ageRange":null,"badge":null,"shopperProfiles":[]},"reviewedDate":null,"purchaseDate":null,"dateCreated":"2025-04-28T00:00:00-04:00","customData":[],"incentiveType":null,"campaign":null,"deviceFingerprint":null,"topics":[],"syndication":{"sourceName":"Mystery Ranch","siteUrl":"https://www.mysteryranch.com/","logoUrl":"https://images.turnto.com/site/syndicationlogos/2558_LH48.png"},"catalogItems":[{"sku":"888564-112899","title":"Mystery Ranch Catalyst 18L Backpacking Backpack","url":"https://www.scheels.com/p/888564-112899","category":"accessories-backpacks","reviewCount":5,"ratingCount":5,"averageRating":4.6,"ratingBreakdown":{"1":0,"2":0,"3":0,"4":2,"5":3},"active":true,"attributes":[]}]},{"id":5512298,"locale":"en_US","rating":5,"title":"Fantastic Day Pack","text":"Great EDC.

Spent a lot of time comparing packs from other well known brands and eventually came back to MR and settled on the Catalyst. Primary requirements were that I wanted similar capacity (18-21L) and needed to have padded back and laptop sleeve. This bag met both of those requirements perfectly. It holds a 16\" Macbook Pro perfectly in the sleeve and has plenty of room for laptop cords and accessories, along with a layer (puffy or rain jacket) and a 32oz nalgene. I like the top zippered pocket, and don't really care that i'm missing exterior pockets/pouches for a water bottle. The Y layout for the zipper and panels looked gimmicky at first but works great for loading/unloading the pack. The shoulder straps are also very comfy and I love the oversized handle on the lid of the pack as well. My only extremely minor gripe about this pack is that the interior zippered pockets on the left and right panels are very shallow, and would have preferred them to be at least 2x the height or even full height of the panel. As they stand those pockets don't offer nearly as much utility as they could and can only accomodate smaller items. Overall very impressed with this pack and look forward to many years of service with it.","textLength":1295,"csFlag":false,"inappropriateFlag":false,"reviewedFlag":false,"autoModerated":false,"published":true,"incentivized":false,"upVotes":1,"downVotes":0,"orderId":null,"dimensions":[],"responses":[],"tags":[],"media":{"photo":[],"video":[],"audio":[]},"user":{"nickName":"d_rek","firstName":null,"lastName":null,"emailAddress":null,"externalId":null,"city":"Michigan","state":null,"country":null,"ageRange":null,"badge":null,"shopperProfiles":[]},"reviewedDate":null,"purchaseDate":null,"dateCreated":"2024-03-07T00:00:00-05:00","customData":[],"incentiveType":null,"campaign":null,"deviceFingerprint":null,"topics":[],"syndication":{"sourceName":"Mystery Ranch","siteUrl":"https://www.mysteryranch.com/","logoUrl":"https://images.turnto.com/site/syndicationlogos/2558_LH48.png"},"catalogItems":[{"sku":"888564-112899","title":"Mystery Ranch Catalyst 18L Backpacking Backpack","url":"https://www.scheels.com/p/888564-112899","category":"accessories-backpacks","reviewCount":5,"ratingCount":5,"averageRating":4.6,"ratingBreakdown":{"1":0,"2":0,"3":0,"4":2,"5":3},"active":true,"attributes":[]}]},{"id":4165625,"locale":"en_US","rating":4,"title":"Almost great!","text":"The strongpoints of this pack are exactly what you would expect.
