I second ThinLine pad. The
Trifecta pad is good, or if you're on a budget, the
Contour pad is a nice option. That's what my daughter uses. It conforms well to the horse's back when it's warmed.
If you want a half pad that will be shock absorbing, is contoured, and you can add shims to if your saddle isn't a perfect fit, I'd recommend a
Skito Interpad or
Skito Correction pad. They are very nice quality custom made pads, made in the USA out of all US made materials (which is almost imposible to find these days...).
If you want sheepskin, then I recommend Engle pads. They are affordable and they use very nicely quality medical grade Merino sheepskin for their saddles pads. They have a
rolled edge pad and a
front roll only pad.
If you want a really nice, hardwood tack trunk, then I'd go with
Horsefare trunks. They are quality built trunks, custom made to order, and are very sturdy. If you want something more affordable, then I'd go with something like
THIS or
THIS. You should be able to find both at Home Depot.
As for other things, I'd get a lunge line, lunge whip,
polo wraps or
horse boots, bell boots,
riding crop or
bat, a bridle, a
leather halter (lasts longer and is just classier than nylon), shampoo,
conditioner,
detangler, hoof pick, body brush, face brush,
curry, sweat scraper, small bucket (for bathing), grooming caddy,
SWAT (great to keep flies off the face and "sensitive parts),
Sheath Cleaner if it's a boy...
I'd also keep in your tack box a small hand towel, a large towel, sponges for tack cleaning and bathing, spare halter and lead, tack cleaning supplies, and first aid supplies.
