Pros & Cons Side by Side

NEMO Tensor Ultralight Sleeping Pad

R-value 3.5 provides 3-season insulation — adequate down to 5°C ground temperature without foam underneath
410g is ultralight for an insulated inflatable — lighter than Thermarest NeoAir at equivalent warmth
Spaceframe baffle construction is 10x quieter than traditional inflatable mattresses — no rustling while sleeping
60cm wide is generous for side sleeping in a tent
Compact packed size fits in top lid of most backpacks without dedicated attachment

£150+ for a sleeping pad requires commitment to ultralight backpacking as a serious pursuit
Inflatable pads are puncture-vulnerable — pack the repair kit
R-value 3.5 not adequate for winter camping below 0°C

Petzl Actik Core 600 Headlamp

USB rechargeable built-in battery — no AAA batteries to carry or replace
600 lumens maximum output matches Black Diamond Spot 400 at higher lumen count
Reactive Lighting automatically adjusts brightness based on what you're looking at — reading vs trail
Red and green wavelength preservation modes protect night vision separately
Petzl's 50-year headlamp heritage — the French brand that defined the professional headlamp category

Built-in battery cannot be swapped — dead battery in remote areas requires USB power source
600 lumens maximum trails the most powerful alternatives at similar pricing
USB charging takes 2 hours from flat — plan ahead
