- ▸Ultralight classification: the Patagonia Micro Puff Hoody is classified ultralight, the Arc'teryx Atom Hoody is not. That usually means the heavier product trades grams for durability or features.

Detailed Breakdown
Carry weight and packed size
On the published spec sheet, the Patagonia Micro Puff Hoody comes in at 264 grams against the 371 grams of the Arc'teryx Atom Hoody. That 107-gram gap may sound trivial in isolation but compounds across multi-day trips — at 25 km a day for a week, you're carrying that delta for about 175 km of trail. The Patagonia Micro Puff Hoody's ultralight classification reflects the deliberate design choices that produce the saving: thinner fabrics, simpler architectures, or fewer secondary features.
Price and total cost of ownership
MSRP gap: $29 (Arc'teryx Atom Hoody cheaper). For most buyers that's the only price number that matters short-term. Long-term cost depends on durability and warranty handling: a product that lasts seven seasons at $329 costs less per use than a product that lasts three at $300. Without long-term field data on both we won't claim a winner on durability, but it's the lens to apply if you re-sell or replace gear infrequently. Look for current sales on either before assuming MSRP is what you'll pay.
Materials and durability
Material composition for both products comes from the manufacturer product pages and is not always reported in directly comparable units. The Patagonia Micro Puff Hoody carries the manufacturer's published spec only; the Arc'teryx Atom Hoody carries the manufacturer's published spec only. Without a full review of either, treat material and durability claims as starting points rather than verdicts. Reader reviews on REI or Amazon (filtered to verified purchases) often reveal failure modes that brand copy doesn't.
Features and ergonomics
Manufacturer feature descriptions: the Patagonia Micro Puff Hoody — PlumaFill synthetic insulated hoody, ~264 g, 10D Pertex Quantum shell.. The Arc'teryx Atom Hoody — Coreloft 60 synthetic insulated hoody, ~371 g, stretch-knit side panels, DWR. Pay particular attention to fit, adjustability, and hand-feel — three dimensions that don't show on a spec sheet and that disproportionately determine whether you'll actually reach for the gear after the first trip.
Use-case fit
The synthetic insulated hoodies category covers a wide range of trip styles. For weight-counted thru-hikes, lean toward the Patagonia Micro Puff Hoody — every gram in your pack rides with you for thousands of kilometers. For weekend trips and base-camp days, weight matters less and durability, comfort, and feature count matter more — the heavier of the two on this page often makes more sense in those scenarios. For three-season generalist use, our recommendation: prioritize the product you can handle in a store or borrow from a friend, because neither has a full review on this site yet.
Brand support and availability
Patagonia and Arc'teryx both produce synthetic insulated hoodies for the North American and EU markets. Availability varies: smaller cottage brands may require direct-from-manufacturer ordering with 2-6 week lead times, while bigger brands stock through REI, Backcountry, and large EU outdoor chains with same-week shipping. Before buying either, check the manufacturer's warranty terms (often 1, 2, or 10 years depending on brand culture) and the brand's reputation for honoring claims on minor failures versus catastrophic ones. Neither product has a full review on this site yet, so check owner reports for warranty experiences before buying.
Frequently Asked Questions
Which is lighter, the Patagonia Micro Puff Hoody or the Arc'teryx Atom Hoody?
On published manufacturer specs, the Patagonia Micro Puff Hoody is the lighter of the two by 107 grams (0.26 kg vs 0.37 kg). For ultralight backpackers counting grams in the synthetic insulated hoodies category, that's a meaningful difference.
Which costs less, the Patagonia Micro Puff Hoody or the Arc'teryx Atom Hoody?
At MSRP, the Arc'teryx Atom Hoody costs $29 less than the Patagonia Micro Puff Hoody ($300 vs $329). Real-world prices fluctuate with sales and seasonal promotions, but the spec-sheet starting price is clear.
Does this site have full reviews of both products?
Not yet. Neither the Patagonia Micro Puff Hoody nor the Arc'teryx Atom Hoody has a full review on this site yet. This comparison is built from published manufacturer specifications only, clearly labeled. Treat it as a shortlist starting point rather than a verdict.
Is the Patagonia Micro Puff Hoody ultralight by industry standards?
Yes. The Patagonia Micro Puff Hoody is classified ultralight in our database (0.26 kg, sub-threshold for its clothing category). Ultralight synthetic insulated hoodies typically means built for thru-hikers and gram counters rather than three-season car-camping use.
Is the Arc'teryx Atom Hoody ultralight by industry standards?
No. The Arc'teryx Atom Hoody at 0.37 kg sits above the ultralight threshold. That usually buys more durability or features at the cost of weight — appropriate for car-camping, base-camp, or shoulder-season trips.
Is the price difference worth it?
The Patagonia Micro Puff Hoody costs $29 more than the Arc'teryx Atom Hoody but is 107 g lighter. That's roughly $0.27 per gram saved. Whether that's worth it depends on how often you carry it: a thru-hiker saving grams every day for months will rationalize the premium more easily than a weekend backpacker.
Where can I read the full review?
