How we test: We own and travel with most of the gear we recommend and put it through real con weekends; the rest we vet with suiters we trust or draw from their first-hand reviews. Where you see photos of a unit in a review, those are our own or friend's and blog supporters.
The backing fabric of a fursuit fails because of salt and moisture, and the cheapest way to protect it is to never let your sweat reach it. A base layer is the barrier. Plain spandex does the covering part, but it holds damp against you; HeatGear is built to move that moisture off your skin and evaporate it, which is a meaningfully different experience by hour three of a con.
The job of a base layer under a suit is to be the thing that gets sweaty instead of the suit. HeatGear's single-layer construction is designed to move sweat to the surface and dry quickly, so you are wearing damp fabric for less of the day and the moisture is not sitting against expensive fur backing.
Full sleeves are the second reason. A partial or a bodysuit with sleeves rubs at the inside of the forearm, and hours of that on bare skin is how suiters end up with a friction burn they only notice at the hotel. A smooth compression sleeve removes the contact point entirely.
In practice it becomes the first thing on and the first thing washed. Because it dries quickly it also survives a mid-con sink wash and an overnight hang, which matters on a long weekend when you did not pack four of them.
The fit is the part to think about honestly. Compression is snug all day, and some people love the support while others find it wearing after ten hours. If you already own compression gear for the gym and like it, you know your answer. If you do not, consider trying one before buying two.
The same kind of product from other makers we haven't reviewed, so you can price-check the pick above.
Best for: A cheaper wicking base-layer top when you want more than one
The budget same-job base-layer top: cool-dry wicking compression long-sleeves with flat, chafe-free seams. Three shirts for the price of one name-brand, so a sweaty suiter can rotate a fresh one each con day.
HeatGear, without exception. HeatGear is the hot-weather line, built to wick sweat and dry fast. ColdGear uses a brushed inner layer to trap body heat, which is the opposite of what you want inside a suit where overheating is the genuine risk.
Spandex is enough to protect the suit, which is the main job. HeatGear does that plus moves moisture off you faster, so you are less clammy and the fur backing stays drier. It is an upgrade you can skip.
It depends on you. Compression is snug by design; some suiters find it supportive, others find it tiring after many hours. If you have never worn compression gear, try one before committing to a full set.
At least two. The layer soaks up everything, so you want a dry one ready while the other washes and dries. HeatGear's fast drying makes a mid-con sink wash realistic.
Not directly. It manages sweat and helps evaporation, which feels cooler, but it does not lower your core temperature. For that you want an evaporative wrap, a cooling vest, and disciplined breaks.
Cold wash and air dry. High heat degrades the elastic fibres over time and shortens the useful life of the stretch, which is most of what you paid for.
