This is where the gear you own lives. Load a sample kit to see how everything fits together, or start from nothing and add your own.
The columns hold everything you own — that's your locker, and you only build it once. Ticking a checkbox puts an item in this trip's loadout. Unticking takes it out of the pack, not out of your locker.
Base weight is what's in the pack minus food, water and fuel — the figure hikers compare. Clothing you mark as worn is on your body, so it doesn't count either. The big readout at the top is always base weight.
Every item works the same way. Nothing here is permanent — edit a weight after you put it on the scale, or remove gear you've sold.
The four buttons are starting points, not fixed menus. Tick and untick until the loadout is right, then hit Update in the green bar to save it as your version of that style. Rename changes the label — "Shoulder season" beats "Full stack" if that's what you actually pack.
Put the pack you're saving for in the Wishlist column. You can still tick it into a loadout to see what it would do to your base weight — the purple bar segment shows how much of your kit you'd have to buy. When it arrives, hit Got it and it moves into your real gear.
Hit Audit at the top to see your loadout ranked heaviest first, with each item as a share of base weight. Weight is almost always concentrated in three or four things — the audit names them, flags anything heavy for its slot, and points out upgrades already sitting on your wishlist.
Your locker is stored in this browser on this device. There's no account and no server, which means nobody can see your data — and also that clearing your browsing data wipes it. Once you've entered your kit, scroll to the bottom and hit Export my locker, then save the file somewhere safe. On a phone, use Share → Add to Home Screen so it opens like an app and works with no signal.

Base weight is everything in the pack except food, water and fuel — the number the ultralight thresholds refer to. The columns hold the gear you own — edit any item's name, weight or column, remove what you've sold, add what you've bought. Anything marked worn comes out of base weight and counts as clothing you have on or poles in your hands. Thresholds: ultralight under 4.5 kg, lightweight under 9.1 kg, traditional above that. Build 15
