Suggestions for gear.

* Comfortable hiking boots! Break them in before coming: use them for at least a couple of hikes. If you have older boots, waterproof them with some boot grease or equivalent. You can also use hiking shoes if you prefer, as the trails will not be demanding at all. However, hiking shoes get wet easier if it rains. Given the high temperatures in Italy this summer, it is highly improbable we'll have to cross any snow fields. Avoid flat-soled shoes as they are slippery if it rains.

* Rain gear, for comfortable walking in the rain: goretex (or similar waterproof) jacket and overpants (or hiking pants). If you don't have good rain gear (or you're uncomfortable in the rain), a large lightweight umbrella usually works fine (unless there's wind, which is not typical). If you don't mind getting your legs wet when it rains, a possibility is to forgo the overpants and just use shorts when it rains.

* Fleece and warm clothes. Italy is a warm country in July (actually, blistering devastatingly hot, stellar plasma-like is more appropriate), but we will be sleeping at 2500 m altitude and higher. Expect temperatures that can dip to 10 degrees Celsius or lower. A great trick is the onion strategy: bring many (not too heavy) layers and modulate them depending on the temperature. With N clothing layers, you have 2N-1 possible combinations (excluding naked): that quickly covers a wide temperature range.

* A comfortable backpack to bring your stuff. No baggage service will be provided!

* Light bathing suit (if you're not comfortable skinny-dipping!). We'll be stopping at some beautiful lakes along the way.

* Paper and pencil. Laptops are discouraged (as there will be limited access to electric power). A laptop and a projector will be provided by the organization for the talks. If you're giving a talk, bring it on a usb pen drive (powerpoint, libreoffice or pdf). Print all the papers and stuff you will need and bring a usb pen drive with the papers you might need (you can consult them on the organizers' computer).

* A small, light flashlight (any cheap LED model will be fine).

* Earplugs!!!! (You will be sleeping in shared rooms.)

* SUNSCREEN and HAT. Also sunglasses, if you're sensitive. Sunscreen may be MANDATORY, depending on your skin tone: UV can be brutal at altitude.

* Change of clothes. We WILL be sweating. Merino wool baselayers (e.g. t-shirt and underwear) are recommended but expensive. Capilene and synthetics are a good cheap alternative. Cotton clothes and blue jeans are banned: once they're wet they do not dry (we WILL get wet, either from sweat or rain). Do not use.

* Bedding for the huts. Look for disposable sleeping bag sheets or sleeping bag liners (silk ones are very nice, light and not too expensive, cotton ones are a cheaper and heavier alternative).

* Toothbrush, toothpaste and towel (the mountain huts may have limited towels for guests, bring a small one for safety).

* Small roll of toilet paper/paper napkins.

* Lightweight water bottle. A disposable 1.5L coke bottle is great: it's durable (sigh), light, tasteless, and squishable when empty.

* Extra shoes or slippers: huts usually have slippers but be aware that we'll be filling them, so there won't be enough for everybody. If you're uncomfortable being barefoot, bring a LIGHTWEIGHT pair.

* Band aids (or electrical tape) for blisters (if you think you might get any).


* Comfort food, such as energy bars and chocolate (meals will be provided in the mountain huts, but do not expect gourmet food!)

* Phone. It will be difficult to charge and there will be limited service at altitude. Things will be better in the lower parts of the tour. If you do bring a phone, also have a usb-cable for charging it: we might not have enough plugs for everyone, but we might have usb ports.

* Walking sticks. Some people love them for walking (and they're great downhill if you have knee problems). Carbon ones are more expensive but extremely lightweight.

Not required:
* Remember that you'll be lugging everything on your shoulders for 5 days. The art of a successful hike is not "knowing what to bring", but "knowing what to leave home".

DO NOT LITTER: bring away everything you bring with you. We will be crossing two natural parks. Do not disturb wildlife (we might be seeing marmots, ibex, chamois, vultures, eagles). Do not pick flowers: if you see a nice flower, take a picture of it. It'll last longer, and is much cheaper (the fines for picking flowers in the Gran Paradiso National park can be several hundred euros, per flower). If you need to go to the bathroom in the wild, please cover after yourself (eg with rocks).

If you see a snake, keep your distance, as it might be a viper (triangular head, blunt tail, vertical eye slits). It's quite rare to see them as they're very shy (the non-shy ones having all been killed over the centuries). Vipers are poisonous, but not very dangerous. Fatalities from viper bites are extremely rare (almost impossible if you're a healthy adult), but apparently a viper bite is extremely painful, you'll need to be airlifted to a hospital, etc. In the extremely unlikely case you're bitten, keep still: the poison spreads itself through the lymphatic system, so it won't spread if you don't move. If you're talking, they'll hear you and run away. One more reason for talking about physics while hiking :-)
