Memorial Day outdoor gear sales: late-May event calendar and top picks

How multi-retailer brand markdowns and MAP holidays work

If you compare product listings at REI Co-op and evo’s outdoor sale hub during the third week of May, you will notice that flagship gear from brands like NEMO Equipment, Cascade Designs (maker of Therm-a-Rest, MSR, and Platypus), Big Agnes, Osprey, and Kelty drops in price on the exact same morning across multiple websites. This coordination is driven by Minimum Advertised Price (MAP) agreements.

Throughout most of the year, outdoor manufacturers contractually prohibit authorized dealers from advertising current-season equipment below a set floor. Twice a year—in late May around Memorial Day and in mid-November ahead of Thanksgiving—manufacturers declare a promotional MAP window. During those ten to fourteen days, every authorized retailer is permitted to apply the brand’s approved promotional reduction on qualifying product lines.

For trail shoppers, this multi-retailer synchronization creates three practical advantages:

1. Preserving single-use member coupons: Because brand-wide markdowns apply automatically in the shopping cart at both REI and evo, you never need to spend a single-use member coupon on a NEMO tent, Therm-a-Rest pad, or MSR stove that is already part of an authorized brand promotion.
2. Cross-checking inventory depth: When a popular item—such as a Regular Wide insulated sleeping pad or a 15-degree down sleeping bag—goes on backorder at one retailer mid-week, you can often find the identical model at the same promotional markdown at a second authorized dealer like evo.
3. Retaining full manufacturer warranty protection: Buying from an authorized dealer during a May MAP window guarantees that your receipt qualifies for the maker’s lifetime defect warranty, unlike grey-market listings from unauthorized third-party sellers.

Coordinating REI’s Anniversary Sale with broader Memorial Day deals

Because the eleven-day REI Anniversary Sale anchors the late-May retail calendar, strategic hikers build their Memorial Day shopping plan around the interaction between catalog markdowns and the single-item member coupon. We cover the co-op’s specific rules in detail in our REI Anniversary Sale guide, but the core principle applies across every retailer you check in May.

According to REI’s official coupon terms, active Co-op members receive a promotional code valid for one eligible full-price item and one eligible REI Outlet closeout item. That coupon cannot be stacked on top of items that are already marked down in the seasonal catalog, and it excludes GPS receivers, satellite messengers, action cameras, bicycles, paddlecraft, roof racks, and snow sports hardware.

To avoid wasting your single-item coupon when shopping across multiple Memorial Day sales:

• Step 1 — Check automatic brand promotions first: Scan the late-May sale catalogs at REI and evo to see which items on your backpacking checklist are already included in an automatic brand-wide promotion. Major lines from NEMO Equipment, Big Agnes, Osprey, Therm-a-Rest, MSR, Platypus, Helinox, Smartwool, and Darn Tough frequently participate in automatic catalog reductions.
• Step 2 — Compare cross-retailer stock on sale items: For gear that is marked down industry-wide—such as the MSR PocketRocket 2 Stove, Platypus QuickDraw Microfilter, or NEMO Disco 15 Down Sleeping Bag—compare availability between REI and evo so you get the exact size or specification you need without delay.
• Step 3 — Reserve the full-price coupon for an unpromoted item: Apply your single full-price member coupon to the highest-ticket piece of gear on your list that is not part of a brand-wide sale—such as a specialty Dyneema backpack from Hyperlite Mountain Gear or a specific wide-last leather hiking boot that rarely enters promotional catalogs.
• Step 4 — Use the Outlet coupon on past-season colorways: Pair your main order with an extra member reduction on one item from REI Outlet, where retired seasonal colors of rain shells and hiking pants already sit at closeout levels.

What outdoor gear to buy during Memorial Day sales

With four months of prime summer trail conditions immediately ahead, Memorial Day sales reward hikers who focus on the high-impact functional systems identified in the National Park Service Ten Essentials and the “Big Three” overnight categories (shelter, sleep system, and pack).

1. Three-season backpacking and camping tents

Shelters represent one of the largest single investments in an overnight kit, and late May is the best time of the year to buy a current-generation tent before summer demand depletes inventory. Both freestanding dome designs and ultralight semi-freestanding shelters regularly participate in Memorial Day brand promotions.

When comparing discounted tents from our best ultralight tents guide, look past marketing banners and verify three structural specifications:

• Rainfly and floor fabric chemistry: Traditional ripstop nylon has high tear strength but absorbs water and stretches during prolonged rainstorms, causing the fly to sag against the inner mesh canopy. Newer composite weaves—such as the proprietary PFAS-free OSMO poly-nylon fabric on the NEMO Hornet OSMO Ultralight 2P Tent (covered in our NEMO Equipment review) or solution-dyed fabrics on the Big Agnes Copper Spur UL2—cut wet stretch and eliminate intentionally added PFAS water-repellent coatings.
• True trail weight versus packed weight: Manufacturers list “trail weight” as the tent body, rainfly, and poles only (excluding stakes, guyline bags, and stuff sacks). Confirm both numbers so you know the real weight entering your pack.
• Pole architecture: DAC Featherlite aluminum alloy poles offer superior strength-to-weight ratios and field repairability compared to heavy fiberglass poles found on bargain mass-market tents. Once your new shelter arrives, practice pitching it at home using our step-by-step guide on how to set up a tent.

2. ASTM-rated sleeping pads and three-season sleeping bags

Ground conduction drains body heat far faster than ambient air when you compress the bottom of a sleeping bag under your body weight. Memorial Day promotions routinely include leading insulated air pads and down or synthetic sleeping bags at both REI and evo.

Because major outdoor retailers require sleeping pads to publish laboratory thermal resistance ratings under the ASTM F3340 standard, you can compare warmth objectively across brands. As we detail in our guide to sleeping pad R-value and our best backpacking sleeping pads rankings, an ASTM R-value between 2.0 and 3.9 covers warm summer trips, while an R-value of 4.0 to 5.4 handles cold alpine basins and shoulder-season frosts without switching mattresses.

Two standout targets during late-May sales are the Therm-a-Rest NeoAir XLite NXT (ASTM R-value 4.5, 13 ounces in Regular) and the NEMO Tensor All-Season Ultralight Insulated (R-value 5.4, 3.5 inches thick). You can weigh their internal baffle engineering side by side in our Therm-a-Rest NeoAir XLite NXT vs NEMO Tensor All-Season comparison. Pair your pad with a compressible down or synthetic bag from our best backpacking sleeping bags guide—such as the Spoon-shaped NEMO Disco 15 or Forte 20, or the value-oriented Kelty Cosmic Down 20—all of which are stocked across REI and evo.

3. Internal-frame backpacking packs and technical daypacks

A backpack must match your spinal torso length—measured from the C7 vertebra at the base of your neck to the top of your iliac crest—rather than your overall height. Buying a pack from our best backpacking backpacks or best hiking daypacks guides during Memorial Day sales ensures that both Small/Medium and Large/Extra-Large frame sizes are available before mid-summer stockouts.

As detailed in our Osprey backpacks review, packs like the Osprey Exos 58 (2.84 pounds in S/M with a tensioned AirSpeed trampoline backpanel) and the close-riding Osprey Talon 22 frequently participate in late-May brand promotions and carry Osprey’s All Mighty Guarantee. Likewise, Co-op members shopping REI’s May sale can target the modular REI Co-op Flash 55 Pack or Flash 22 Daypack during Co-op brand promotional windows. After choosing a frame, follow our guide on how to pack a backpack to keep heavy items centered against your lumbar spine.

4. Camp kitchen stoves, water filters, and basecamp chairs

Smaller hardware systems rarely require complex sizing, making them straightforward additions to a Memorial Day cart at either REI or evo:

• Backpacking stoves: Cascade Designs and Johnson Outdoors frequently include canister burners and integrated boiling systems in late-May promotions. Check our best backpacking stoves guide and our head-to-head MSR PocketRocket 2 vs Jetboil Flash comparison to decide between a 2.6-ounce modular burner like the MSR PocketRocket 2 and a wind-shielded regulated system like the MSR PocketRocket Deluxe or Jetboil MiniMo.
• Backcountry water filters: Summer warmth accelerates biological activity in backcountry streams, making a 0.1-micron or 0.2-micron hollow-fiber filter mandatory. Compare flow rates and thread compatibility in our best backpacking water filters guide and our Sawyer Squeeze vs Platypus QuickDraw breakdown before picking up a Platypus QuickDraw Microfilter System.
• Camp chairs: Whether you are building a lightweight trail seat or outfitting a vehicle basecamp from our car camping checklist, late May brings promotions on both the sub-two-pound Helinox Chair One and the suspended auto-reclining NEMO Stargaze chair featured in our best camping chairs guide.

5. Trail footwear and merino wool hiking socks

If your summer itinerary includes rocky alpine passes or multi-day scrambles, buying footwear during Memorial Day sales gives you late May and June to break in leather uppers and dial in lacing tension before July trips. Review our guides to the best hiking boots for women, best hiking boots for wide feet, and best hiking sandals, and pair them with high-density merino wool crew socks from our best hiking socks guide. Reading our hiking boot fit guide and how to prevent blisters hiking ensures you test heel lock and downhill toe clearance while your boots are still clean and eligible for indoor return exchanges.

What to skip during Memorial Day sales (and when to buy instead)

While late May is the premier window for three-season trail gear, three equipment categories are usually better purchased during other seasonal windows:

1. Dedicated winter mountaineering and deep-cold insulation: Heavy belay parkas, sub-zero expedition sleeping bags, snowshoes, and winter traction hardware receive relatively modest attention in May because retailers have already packed away winter inventory. Wait for late-winter clearance in February and March—covered in our end-of-season gear clearance guide—or shop late-summer closeouts during Labor Day outdoor gear sales.
2. Small-batch cottage Dyneema gear excluded from spring sales: While some cottage makers run Memorial Day events, several custom quilt and Dyneema shelter builders hold their deepest annual sitewide promotions in mid-to-late November. If a cottage brand does not discount in May, bookmark our Black Friday outdoor gear deals calendar for November.
3. Electronic satellite messengers when excluded from coupons: Standard member coupons exclude GPS and satellite communication hardware. Unless a manufacturer like Garmin is running an authorized instant rebate during Memorial Day week, compare manufacturer rebate windows across July’s Prime Day outdoor gear deals and November holiday promotions.
