TRINORDIC Small Ultralight Foldable Backpack Review

Overview

The TRINORDIC Small Ultralight Foldable Backpack is a 12-liter, 70-gram stuff-into-itself daypack aimed at travelers and hikers who want a “just in case” bag rather than a primary pack. It’s the kind of thing you throw in the bottom of a carry-on or clip inside your main backpacking pack for summit days, grocery runs, or as an overflow bag when your souvenir haul outgrows your luggage. This isn’t gear for multi-day trail use — think of it as an emergency day bag, not a replacement for a dedicated 20-30L daypack.

Performance

At 70 grams, this pack is essentially weightless in your kit — lighter than a typical stuff sack, let alone a dedicated summit pack. It folds down small enough that it can be folded to fit almost in the palm of your hand or put in your pockets, at least jacket pockets. That’s the whole pitch, and on that front it delivers exactly what it promises.

Where it gets more interesting is capacity. Despite the tiny packed size, this folding backpack can be opened and offers plenty of space for all your important items, making it ideal for everyday use like grocery shopping or as an additional backpack for travel. One buyer noted it can be folded to a very small size and when unfolded it can carry quite a few large items — which tracks with what I’d expect from a 12L ripstop shell with no internal frame or padding.

Comfort is a pleasant surprise for something this minimal. TRINORDIC uses extra-wide straps that distribute weight evenly, ensuring maximum comfort even when the backpack is fully packed, and at least one reviewer specifically called out that the wide shoulder straps make it very comfortable to wear. That said, “comfortable” here is relative — there’s no hip belt, no frame sheet, and no back padding, so once you load it past a few pounds (a rain jacket, some snacks, a water bottle) you’ll feel every bit of it directly on your shoulders. This is a bag for light loads, full stop.

Material-wise, the ripstop polyester and YKK zip combo is a smart pairing for a pack this cheap and this light — YKK zippers are a meaningfully better bet than the generic zippers you see on similar no-name folding packs, and ripstop weave means small snags are less likely to turn into blowouts. TRINORDIC advertises the pack as durable and water-resistant, made from durable ripstop polyester with a YKK zipper — note that’s water-resistant, not waterproof, so don’t expect it to save your electronics in a downpour. There’s no seam-taping or DWR treatment mentioned, so treat it like any other uncoated ripstop shell: fine for light drizzle, not for sustained rain.

The single external side pocket is a nice touch for a bottle or a compact umbrella, and the oversized zipper pull is a small but genuinely useful detail when you’re fumbling with cold or gloved hands. What you don’t get: any internal organization, a laptop sleeve, or load-lifter straps — this is a single open compartment and that’s it.

I couldn’t find independent long-term durability testing or dedicated threads on r/Ultralight, Backpacking Light, or CleverHiker specifically covering this pack — it’s a newer, Amazon-native product without much third-party coverage yet. Amazon’s own review aggregation for the listing notes that customers like the compact size, weight, and portability of the backpack, mentioning it’s small but has enough room and is a great travel companion, which lines up with the individual reviews above, but I’d treat this as anecdotal rather than rigorous field testing.

Pros & Cons

Pros:

• Genuinely tiny packed size and negligible weight (70g) — easy to justify carrying “just in case”
• Wide, padded straps make it more comfortable than most packable daypacks in this weight class
• YKK zipper and ripstop polyester are above-average material choices for a sub-$20 packable bag
• Side pocket and oversized zipper pull are thoughtful, practical details
• 2-year warranty is generous for a product at this price point

Cons:

• No frame, hip belt, or back padding — loads over a few pounds get uncomfortable fast
• Water-resistant only, not waterproof — no seam sealing mentioned
• No internal organization or laptop sleeve
• Limited independent long-term durability data; it’s a newer product without much trail-tested track record
• Not a substitute for a real daypack if you’re hiking more than a few miles with real gear

Who Should Buy This

This pack makes the most sense as a backup or contingency item: something you toss into a backpacking pack’s brain pocket for a low-key summit push, or stash in checked luggage for grocery runs and market days on a trip. Thru-hikers who want a featherweight in-town errand bag or a spare for resupply days will get real use out of it. It is not the right choice for anyone planning to use it as their primary daypack on actual hikes — the lack of a frame and padding will make itself known once you’re carrying more than a light jacket and a snack.

Verdict

For 70 grams and a low price, the TRINORDIC delivers on its narrow promise: it’s absurdly packable, surprisingly comfortable for what it is, and built with better-than-expected materials. It’s a smart “just in case” addition to a travel or backpacking kit, but don’t mistake it for a real daypack — I’d rate it a 6.5/10 as a niche convenience item, with the caveat that independent long-term durability testing is still thin.
