What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Big Agnes Copper Spur HV UL2 Tent
Only one whitelisted tester — Digital Trends — has a hands-on review, and it covers the Copper Spur HV UL2 mtnGLO (the LED trim of the same base HV UL2 tent, identical construction, dimensions and setup). It was field-tested across a full Pacific Northwest season for the 2017 Outdoor Awards (republished 2023-04-25). Digital Trends praised the fast pitch, durable ripstop, and interior LEDs, but called the tent snug for two. (1 sourced review, 1 lab-tested.)
Praised: Fast, easy pitch — up in 4-5 minutes with the rain fly; Interior LED light strip lights the whole tent and is barely visible from outside (mtnGLO trim only); Durable ripstop nylon that held up over a full season of field use.
Flagged: Interior is snug for two occupants.
NEMO Dagger OSMO 2P Tent
Three hands-on reviewers (Switchback Travel, CleverHiker, GearJunkie) rate the NEMO Dagger OSMO 2P a top livability pick: roomy near-vertical walls with generous headroom, large trapezoidal vestibules plus the waterproof Landing Zone gear tub, easy freestanding setup, and no-sag OSMO fabric that stays dry. All three flag it as heavier than rivals and not a lightweight or long-distance choice; two also cite a premium price and only-mediocre ventilation. No lab-measured numbers were reported, and each outlet tested a different model year, so quoted weights and prices differ. (3 sourced reviews.)
Praised: Roomy, livable interior with near-vertical walls and generous headroom; Large trapezoidal vestibules plus the waterproof Landing Zone gear tub; OSMO fabric resists sagging when wet and keeps the interior dry.
Flagged: Heavier than comparable backpacking tents; not a lightweight or long-distance choice; Premium price; Ventilation is only mediocre and can get clammy or hold condensation in humid conditions.
