The ESA Huygens probe very accurately characterized the conditions at its landing site on Titan's surface and verified measurements made by the Voyager 1 Radio Science (VRS) investigation nearly 25 years earlier. It measured a surface temperature of 93.8K (VRS: 94.0 ± 0.7 K), a surface pressure of 1467 mb (VRS: 1496 ±20 mb), a methane abundance of 5.65 ± 0.18 % by volume in otherwise almost pure nitrogen, and near-surface winds in the 0.5-1 m/s range, in good agreement with detailed global circulation models. The atmosphere's composition, temperature, and pressure make for a mass density at the surface of ~4 times the density of Earth's atmosphere at sea level.
On Earth, planning a hiking trip requires at least a little forethought. Will the hike be a daytime hike in the Sahara or a winter hike at the south pole, or somewhere between? The huge range of conditions possible at Earth has a big effect on the kinds of gear you'd need to take.
Not so at Titan. In some ways Titan is like Venus: its dense atmosphere is very efficient at moving heat from sources such as solar energy all over Titan. Like Venus, anywhere you go on Titan, locations at the same elevation show very little temperature difference. The Wikipedia article on Titan's climate says "Titan is about 12% closer to the sun during the southern hemisphere summer, making southern summers shorter but hotter than northern summers." Hotter?? All the observations indicate that the largest temperature difference to be found at Titan, from the subsolar latitude in summer to the winter pole, is ~3.5 K! So one suit will do wherever you go on Titan.
And suit it would be, as @peterh says. Not a full space suit, since it doesn't need to maintain increased pressure inside, but you just can't let any part of your body be exposed directly to Titanian air at 94 K.
The suit also needs to supply breathable air, and here there's a bit of a twist. You simply can't plan on breathing pure oxygen at nearly 1.5 bars pressure. In addition to the extreme fire hazard, it's also a health hazard. And you probably don't want to try to maintain the pressure inside the suit at ~1/3 bar so you could use pure oxygen. Running such a pressure difference would make the suit much heavier and stiffer. So in addition to carrying oxygen, you need some way to provide an inert gas to make up the difference in pressure. You can't just bring in Titanian air, heat it, and mix oxygen with it. It's not that methane is toxic, to the contrary it's fairly benign in that regard. It's that 5+% methane mixed with oxygen is a combustible mixture, so it would be an accident just waiting to happen. If you use Titanian air for the background gas, you have to take most of the methane out of it, and that takes energy.
Fortunately, removing methane by condensing it would require cooling the Titanian air by less than 20K. This is not particularly difficult and could be done with a Peltier cooler. Cooling exhaled gas to ~195 K will condense out CO2 for rebreathing of what's left, notably the oxygen. No cooling mechanism is needed for that, just something akin to a car's radiator to reject heat to the Titanian atmosphere. This would also condense out water, which you'd want to return to the scrubbed (of CO2) air. Having two different temperatures in the scrubber is probably the best approach, the warmer one to remove (for subsequent return) most of the water but not CO2, the colder one to scrub CO2 for disposal.
If you're not going to use Titanian air then you have to bring your own background gas, whether nitrogen, helium, or whatever. It wouldn't have to be in a separate tank, but the contents of a single tank would be only ~15% oxygen. If you used scrubbed Titanian air, your tank could contain 100% oxygen, allowing longer durations before needing replenishment.
The suit needs to keep you warm. My friend and colleague Julian Nott, the accomplished balloonist who has analyzed the potential for balloon flight at Titan, has looked into how much insulation would be required to maintain comfortable temperatures inside a suit using only body heat. His (unpublished) result: the suit gets pretty thick, and might hinder movement. You could make the suit thinner by using a suit heater, but that takes more energy. That's a trade yet to be made: do you make the suit thicker, to use less energy for heating, or thinner with a suit heater, to ease mobility?
There's another item the suit will need. Regardless of which options are chosen, electric power will be needed, so some kind of battery, or fuel cell, or some other source of electric power will be needed. It won't be a solar array! Light levels at noon on Titan's surface are roughly 1/1000 of full sunlight on Earth. Titan's clouds and haze make the sunlight diffuse, so you can't make an effective concentrator. So much for solar for relatively power-hungry activities on Titan! But battery technology has come a long way since the Apollo days, so a relatively light battery (especially in Titan's ~1/7 g!) could supply enough power for the suit.
None of the challenges outlined here appear to be show-stoppers. The biggest challenge is in getting to Titan in the first place!
Once there, in that low gravity and thick atmosphere, you could don your suit, strap some relatively small wings onto you arms, flap your arms—and fly! (with reference to Robert Zubrin's 1999 book) I would recommend some training before you try it, though.
